前言

今天复习一下SpringMVC+Hibernate的搭建，本来想着将Spring-Security权限控制框架也映入其中的，但是发现内容太多了，Spring-Security的就留在下一篇吧，这篇主要搭建SpringMVC4.1.4和Hibernate4.3.8，之前也打了好多SpringMVC的，这部分已经非常的熟悉了，毕竟业开发过一年多SpringMVC的，这次持久层采用Hibernate，数据源采用c3p0，数据库暂采用MySQL，主要是想复习一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下：

1、设计数据库：设计好表结构，最好符合3NF，采用Hibernate tools将设计好的表自动生成对应的实体entity。

1、创建Maven项目，按需映入Maven包依赖。

2、搭建Spring：配置Spring对控件层Bean的注入。

3、搭建Hibernate：配置数据源，配置SessionFactory，配置事务，以及二级缓存ehcache的配置。

4、测试Spring+Hibernate的框架搭建，写单元测试JUnit，测试事务配置等。

5、映入SpringMVC：配置SpringMVC配置信息。

6、配置web.xml容器

7、测试三个框架的整合：Maven编译打包部署服务器，测试。

1、数据库设计

设计一个权限、角色、用户的表。自然如果一个用户可以有多个角色，一个角色多个用户所拥有；一个角色拥有多个权限，一个权限对应多个角色。所以按照数据库表结构设计，符合3NF的话我们需要5张表进行存在。表的具体信息就不列出了（可以下在源码，里面还有数据库），表关系如下：

这里面ID才用到是java的UUID（36位）

2、创建Maven项目，编写pom.xml文件

创建一个Maven的webapp项目，编写pom.xml文件，引入所需的包依赖，我这里就将所需的全部的映入了。

pom.xml文件内容如下:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

</build> </project>

3、引入Spring配置

编写配置文件，配置文件放在src/main/resources资源目录下（下同）。

项目所需的配置信息config.properties

#application configs #jdbc c3p0 config jdbc.driver = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8 jdbc.username = root jdbc.password = 12345 #hibernate config hibernate.dialect = org.hibernate.dialect.MySQLDialect hibernate.show_sql = true hibernate.format_sql = false hibernate.hbm2ddl.auto = update hibernate.cache.use_second_level_cache = true hibernate.cache.use_query_cache = true hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory hibernate.cache.provider_configuration_file_resource_path = ehcache.xml

3.1、spring配置

spring.xml的配置文件如下：

<"1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <> <context:property-placeholder location="classpath:config.properties"/> <> <context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" /> </beans>

上面spring配置了对应包下组件bean自动注入管理，我们需要将dao,service的实现类交由spring管理，如（@Repository，@Service）。

3.2、引入日志文件配置Log4j

log4j.properties的配置文件如下： ### set log levels ### log4j.rootLogger = INFO , C , D , E ### console ### log4j.appender.C = org.apache.log4j.ConsoleAppender log4j.appender.C.Target = System.out log4j.appender.C.layout = org.apache.log4j.PatternLayout log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n ### log file ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log log4j.appender.D.Append = true log4j.appender.D.Threshold = INFO log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n ### exception ### log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

4、Hibernate配置

Hibernate的配置主要包括：配置数据源c3p0，配置SessionFactory，配置事务管理器，配置事务管理，其spring-hibernate.xml文件如下：

<"1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"> <> <bean id="dataSource" destroy-method="close"> <property name="driverClass" value="${jdbc.driver}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <> <property name="checkoutTimeout" value="30000" /> <> <property name="idleConnectionTestPeriod" value="30" /> <> <property name="maxIdleTime" value="30" /> <> <property name="initialPoolSize" value="5" /> <property name="minPoolSize" value="5" /> <property name="maxPoolSize" value="20" /> <> <property name="acquireIncrement" value="5" /> </bean> <> <bean id="sessionFactory" > <> <property name="dataSource" ref="dataSource" /> <> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <> <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop> <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop> <prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop> <prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path} </prop> </props> </property> <> <property name="packagesToScan" value="org.andy.work.entity" /> </bean> <> <bean id="transactionManager" > <property name="sessionFactory" ref="sessionFactory" /> </bean> <> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="load*" propagation="SUPPORTS" read-only="true" /> <> <tx:method name="*" /> </tx:attributes> </tx:advice> <> <aop:config> <> <aop:pointcut id="transactionPointcut" expression="execution(* org.andy.work.service..*Impl.*(..))" /> <> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config> </beans>

上面配置了二级缓存，ehcache，相关的具体信息查看上一篇Hibernate二级缓存以及ehcache的搭建配置，下面是二级缓存的配置。

4.1、ehcache.xml的配置

<"1.0" encoding="UTF-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd"> <diskStore path="D:/ehcache" /> <> <defaultCache maxElementsInMemory="1000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" maxElementsOnDisk="1000000" overflowToDisk="true" memoryStoreEvictionPolicy="LRU"> </defaultCache> <> <cache name="org.andy.work.entity.AcctUser" maxElementsInMemory="2" memoryStoreEvictionPolicy="LRU" eternal="true" diskPersistent="false" overflowToDisk="false" maxElementsOnDisk="1000000" /> </ehcache>

上面Hibernate二级缓存ehcache存放磁盘是D:/ehcache

5、生成业务entity实体

设计好数据表后，Hibernate的实体有工具Hibernate tools自动生成，Eclipse需要安装Hibernate tools插件（我在线安装过几次都不成功，推荐使用links离线安装，附录将介绍），所以不需要手工的书写，下面就贴一个用户信息的实体，AcctUser.java

package org.andy.work.entity; // Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0 import java.util.Date; import java.util.HashSet; import java.util.Set; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.JoinTable; import javax.persistence.ManyToMany; import javax.persistence.Table; import javax.persistence.Temporal; import javax.persistence.TemporalType; import org.hibernate.annotations.Cache; import org.hibernate.annotations.CacheConcurrencyStrategy; import com.fasterxml.jackson.annotation.JsonIgnoreProperties; /** * AcctUser generated by hbm2java */ @Entity @Table(name = "acct_user", catalog = "work") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class AcctUser implements java.io.Serializable { /** * */ private static final long serialVersionUID = 6980093847795726310L; private String id; private String nickName; private String telephone; private Date registerTime; private Set<AcctRole> acctRoles = new HashSet<AcctRole>(0); public AcctUser() { } public AcctUser(String id, String nickName) { this.id = id; this.nickName = nickName; } public AcctUser(String id, String nickName, String telephone, Date registerTime, Set<AcctRole> acctRoles) { this.id = id; this.nickName = nickName; this.telephone = telephone; this.registerTime = registerTime; this.acctRoles = acctRoles; } @Id @Column(name = "id", unique = true, nullable = false, length = 36) public String getId() { return this.id; } public void setId(String id) { this.id = id; } @Column(name = "nick_name", nullable = false) public String getNickName() { return this.nickName; } public void setNickName(String nickName) { this.nickName = nickName; } @Column(name = "telephone") public String getTelephone() { return this.telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } @Temporal(TemporalType.TIMESTAMP) @Column(name = "register_time", length = 19) public Date getRegisterTime() { return this.registerTime; } public void setRegisterTime(Date registerTime) { this.registerTime = registerTime; } @JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"}) @ManyToMany(fetch = FetchType.LAZY) @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) @JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) }) public Set<AcctRole> getAcctRoles() { return this.acctRoles; } public void setAcctRoles(Set<AcctRole> acctRoles) { this.acctRoles = acctRoles; } }

上面有几个需要注意的：

上面大多数都是Hibernate tools自动生成的，但是有几个需要手动添加：

1、如果这个实体使用二级缓存的话，需要添加@cache注解；

2、如果该实体里面还有集合元素（set， map，list），如果实体要采用二级缓存，那么这些集合元素必须也添加@cache注解。

3、@JsonIgnoreProperties注解是为了防止SpringMVC在json返回时产生循环输出使用，如果不配置的话就会出现json死循环（还有多对多，一对多的属性时）。

4、@JsonIgnore这个是在转换成json是忽略该属性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})则是忽略acctRoles里面的acctUsers和acctAuthorites属性。

6、创建Dao层

6.1Dao接口

Dao层和Service层我们肯定采用的是面相接口编程的思想，所以，我们先定义一个通用的Dao接口，GenericDao.java

package org.andy.work.dao; import java.io.Serializable; import java.util.List; /** * 创建时间：2015-2-6 下午2:26:42 * * @author andy * @version 2.2 * * Dao通用接口 */ interface GenericDao<T, PK extends Serializable> { T load(PK id); T get(PK id); List<T> findAll(); void persist(T entity); PK save(T entity); void saveOrUpdate(T entity); void delete(PK id); void flush(); }

在定义具体的UserDao.java接口

package org.andy.work.dao; import org.andy.work.entity.AcctUser; /** * 创建时间：2015-2-6 下午2:43:50 * * @author andy * @version 2.2 * * 用户Dao接口 */ public interface UserDao extends GenericDao<AcctUser, String> { }

6.2、Dao层实现类

我们需要将Dao层的实现类注入为bean，所以需要添加@Repository注解，UserDaoImpl如下：

package org.andy.work.dao.impl; import java.util.List; import org.andy.work.dao.UserDao; import org.andy.work.entity.AcctUser; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; /** * 创建时间：2015-2-6 下午2:45:14 * * @author andy * @version 2.2 */ @Repository("userDao") public class UserDaoImpl implements UserDao { @Autowired private SessionFactory sessionFactory; private Session getCurrentSession() { return this.sessionFactory.getCurrentSession(); } @Override public AcctUser load(String id) { return (AcctUser) this.getCurrentSession().load(AcctUser.class, id); } @Override public AcctUser get(String id) { return (AcctUser) this.getCurrentSession().get(AcctUser.class, id); } @SuppressWarnings("unchecked") @Override public List<AcctUser> findAll() { List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list(); return acctUsers; } @Override public void persist(AcctUser entity) { this.getCurrentSession().persist(entity); } @Override public String save(AcctUser entity) { return (String) this.getCurrentSession().save(entity); } @Override public void saveOrUpdate(AcctUser entity) { this.getCurrentSession().saveOrUpdate(entity); } @Override public void delete(String id) { AcctUser entity = this.load(id); this.getCurrentSession().delete(entity); } @Override public void flush() { this.getCurrentSession().flush(); } }

7、创建Service层

7.1、Service层接口

package org.andy.work.service; import java.util.List; import org.andy.work.entity.AcctUser; /** * 创建时间：2015-2-6 下午3:18:57 * * @author andy * @version 2.2 * userService接口 */ public interface UserService { AcctUser load(String id); AcctUser get(String id); List<AcctUser> findAll(); void persist(AcctUser entity); String save(AcctUser entity); void saveOrUpdate(AcctUser entity); void delete(String id); void flush(); }

7.2、service层实现类

UserServiceImpl就需要注入上面定义的Dao层bean。

package org.andy.work.service.impl; import java.util.List; import org.andy.work.dao.UserDao; import org.andy.work.entity.AcctUser; import org.andy.work.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; /** * 创建时间：2015-2-6 下午3:24:16 * * @author andy * @version 2.2 UserService 的实现 */ @Service("userService") public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public AcctUser load(String id) { return userDao.load(id); } @Override public AcctUser get(String id) { return userDao.get(id); } @Override public List<AcctUser> findAll() { return userDao.findAll(); } @Override public void persist(AcctUser entity) { userDao.persist(entity); } @Override public String save(AcctUser entity) { return userDao.save(entity); } @Override public void saveOrUpdate(AcctUser entity) { userDao.saveOrUpdate(entity); } @Override public void delete(String id) { userDao.delete(id); } @Override public void flush() { userDao.flush(); } }

8、测试Spring和Hibernate的整合

我们可以在src/test/java编写测试类，测试上面的配置，如果测试成功已经基本大功告成。

package org.andy.work.service; import java.util.Date; import java.util.List; import java.util.UUID; import org.andy.work.entity.AcctUser; import org.apache.log4j.Logger; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.alibaba.fastjson.JSON; /** * 创建时间：2015-2-6 下午3:31:07 * * @author andy * @version 2.2 */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:spring.xml", "classpath:spring-hibernate.xml" }) public class TestUserService { private static final Logger LOGGER = Logger .getLogger(TestUserService.class); @Autowired private UserService userService; @Test public void save() { AcctUser acctUser = new AcctUser(); acctUser.setId(UUID.randomUUID().toString()); acctUser.setNickName("andy"); acctUser.setRegisterTime(new Date()); acctUser.setTelephone("13022221111"); String id = userService.save(acctUser); LOGGER.info(JSON.toJSONString(id)); } }

9、引入SpringMVC

添加spring-mvc.xml文件

<"1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <> <context:component-scan base-package="org.andy.work.controller" /> <> <mvc:annotation-driven> <> <mvc:message-converters register-defaults="true"> <bean > <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <> <bean > <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/views" /> <property name="suffix" value=".jsp" /> </bean> </beans>

上面配置了包扫描Controller，[email protected]��，和视图层的配置。

10、配置web.xml容器

web容器是web项目的大脑，所以web容器，首先需要引入spring，让spring管理各个框架，并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。

web.xml文件如下：

<"1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>springmvc_demo</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value> </context-param> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <> <filter> <filter-name>openSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> </filter> <> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <servlet> <description>spring mvc servlet</description> <servlet-name>rest</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>rest</servlet-name> <url-pattern>*.htmls</url-pattern> </servlet-mapping> <filter-mapping> <filter-name>openSessionInViewFilter</filter-name> <url-pattern>*.htmls</url-pattern> </filter-mapping> <> <session-config> <session-timeout>30</session-timeout> </session-config> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>

11、创建控制层Controller

控制层UserController

package org.andy.work.controller; import java.util.List; import org.andy.work.entity.AcctUser; import org.andy.work.service.UserService; import org.apache.log4j.Logger; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; /** * 创建时间：2015-2-7 上午11:49:00 * @author andy * @version 2.2 * 描述：用户Controller */ @Controller @RequestMapping("/user") public class UserController { private static final Logger LOGGER = Logger.getLogger(UserController.class); @Autowired private UserService userService; @RequestMapping("/showInfo/{userId}") public String showUserInfo(ModelMap modelMap, @PathVariable String userId){ LOGGER.info("查询用户：" + userId); AcctUser userInfo = userService.load(userId); modelMap.addAttribute("userInfo", userInfo); return "/user/showInfo"; } @RequestMapping("/showInfos") public @ResponseBody List<AcctUser> showUserInfos(){ LOGGER.info("查询用户全部用户"); List<AcctUser> userInfos = userService.findAll(); return userInfos; } }

12、创建视图层

在src/main/webapp/WEB-INF/views下创建user/showInfo.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%> <% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <base href="<%=basePath%>" /> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script> <title>userInfo</title> </head> <body> 用户信息昵称： ${userInfo.nickName} 用户id：${userInfo.id} 用户电话:${userInfo.telephone } 注册时间： <fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" /> 角色：[ <c:forEach items="${ userInfo.acctRoles}" var="role"> ${role.name } 权限[ <c:forEach items="${ role.acctAuthorities}" var="authority"> ${authority.name } </c:forEach> ] </c:forEach> ] <br /> ajax显示全部用户信息： <div id="show_all_user"></div> </body> <script type="text/javascript"> $.ajax({ type : "get", url : "user/showInfos.htmls", dataType : "json", success : function(data) { $(data).each( function(i, user) { var p = "<p>昵称:" + user.nickName + " 电话:" + user.telephone + " 注册时间:" + user.registerTime + " id:" + user.id + "</p>"; $("#show_all_user").append(p); }); }, async : true }); </script> </html>

13、部署服务器测试

使用Maven打包部署：clean compile package

部署到tomcat，测试

主要测试上面的 http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls

和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls （json数据返回）

上面视图层就包含了这两条url请求的测试：
