Java的批量添加数据，多个字段同时添加多条数据，我不知道你遇到过没有。今天我们就以一个具体的实例来说一下Java的批量添加数据，面向的是Oracle数据库。
前台页面：
<span><body scroll="no"> <div> <form name="webform" method="post"> <div> <div> <div id="baseinfo">基本信息</div> <div id="semsinfo" >页签1</div> <div id="changeinfo"style="margin-right:2px;" >页签2</div> <div id="familyinfo" >页签3</div> <div id="changeinfo"style="margin-right:2px;" >页签4</div> <div id="familyinfo" >页签5</div> <div id="familyinfo" >页签6</div> </div> </div> <div id="bankCardDiv"> <div> <div>信息展示 <input id="addBank" type="button" value="新增一行" /> </div> <div> <table id="parttable" width='100%' border='0' cellspacing='1' cellpadding='0'> <tr> <th>序号</th> <th>属性1</th> <th>属性2</th> <th>属性3</th> <th>属性4</th> <th>属性5</th> <th>属性6</th> <th>属性7</th> <th>属性8</th> <th>属性9</th> <th>操作</th> </tr> <c:if test="${fn:length(personFamilyInfoList) > 0}"> <c:forEach items="${personFamilyInfoList}" var="personFamilyInfoList" varStatus="st"> <tr> <> <td>${st.count} <input type="hidden" name="personFamilyInfoList[${st.count-1}].SGuid" value="${personFamilyInfoList.SGuid}"/> <input type="hidden" name="personFamilyInfoList[${st.count-1}].SPersonGuid" value="${personFamilyInfoList.SPersonGuid}"/> <input type="hidden" name="personFamilyInfoList[${st.count-1}].SUnitGuid" value="${personFamilyInfoList.SUnitGuid }"> <input type="hidden" name="personFamilyInfoList[${st.count-1}].isEnable" value="${personFamilyInfoList.isEnable }"> </td> <> <td> <input id="sFamilyName${st.count-1}" type="text" name="personFamilyInfoList[${st.count-1}].SFamilyName" maxlength="20" value="${personFamilyInfoList.SFamilyName}"> </td> <> <td> <input id="sFamilyIdcardNo${st.count-1}" type="text" name="personFamilyInfoList[${st.count-1}].SFamilyIdcardNo" maxlength="20" value="${personFamilyInfoList.SFamilyIdcardNo}"> </td> <> <td> <select id="iFamilySex${st.count-1}" name="personFamilyInfoList[${st.count-1}].IFamilySex"> <zw:basedictlist itemCode="<%=Constants.I_PERSON_SEX %>" selectValue="${personFamilyInfoList.IFamilySex}"></zw:basedictlist> </select><font color="red">*</font> </td> <> <td> <select id="sFamilyRelation${st.count-1}" name="personFamilyInfoList[${st.count-1}].SFamilyRelation"> <zw:basedictlist itemCode="<%=Constants.S_FAMILY_RELATION %>" selectValue="${personFamilyInfoList.SFamilyRelation}"></zw:basedictlist> </select><font color="red">*</font> </td> <> <td> <input id="sFamilyInsurancePlace${st.count-1}" type="text" name="personFamilyInfoList[${st.count-1}].SFamilyInsurancePlace" maxlength="20" value="${personFamilyInfoList.SFamilyInsurancePlace}"> </td> <> <td> <input id="sFamilyResidencePalce${st.count-1}" type="text" name="personFamilyInfoList[${st.count-1}].SFamilyResidencePalce" maxlength="20" value="${personFamilyInfoList.SFamilyResidencePalce}"> </td> <> <td> <input id="sFamilyPhone${st.count-1}" type="text" name="personFamilyInfoList[${st.count-1}].SFamilyPhone" maxlength="20" value="${personFamilyInfoList.SFamilyPhone}"> </td> <> <td> <input id="dDentifySucessDate${st.count-1}" type="text" name="personFamilyInfoList[${st.count-1}].DDentifySucessDate" value="${personFamilyInfoList.DDentifySucessDate}" onfocus="WdatePicker()" notnull="true" vdisp="首次参保时间" size="18" maxlength="18"/> <font color="red">*</font> </td> <> <td> <input id="dDentifyLostDate${st.count-1}" type="text" name="personFamilyInfoList[${st.count - 1}].DDentifyLostDate" value="${personFamilyInfoList.DDentifyLostDate}" onfocus="WdatePicker()" notnull="true" vdisp="首次参保时间" size="18" maxlength="18"/> </td> <td>取消</td> </tr> </c:forEach> </c:if> </table> </div> </div> </div> <div> <div> <table> <tr> <td width="100%" align="center"> <input id="btnNextstep" type="button" value="上一步" /> <input id="btnAdd" type="button" value="保存" /> <input id="" type="button" value="完成" /> <input id="btnReturn" type="button" value="返回" /> </td> </tr> </table> </div> </div> </form> </div> </body></span>

后台添加方法:

后台更新方法：
<span>/** * <p>Description: 批量更新信息</p> * @param personFamilyInfolist 实体列表 * @param personId 人员id * @return 布尔值，true代表更新成功，否则更新失败 * @throws Exception * @author : gaoying * @update : * @date : 2015-7-20 */ public void updatePersonFamilyInfo(List<PersonFamilyInfo> personFamilyInfolist, String personId) throws Exception{ //根据人员id查询页面有多少条数据 List<PersonFamilyInfo> oldPersonFamilyInfolist = personFamilyInfoService.getPersonFamilyInfoByPersonId(personId); int num = oldPersonFamilyInfolist.size(); if(personFamilyInfolist != null&&personFamilyInfolist.size() > 0){ //检查页面的信息是否有修改，然后更新到数据库 for(int i = 0; i<num; i++){ try{ //设置一个布尔值，如果变动字段设置为false,如果不变动则设置为true boolean bool = true; //判断哪些字段更改过 if(!oldPersonFamilyInfolist.get(i).getSFamilyName().equals(personFamilyInfolist.get(i).getSFamilyName())){ bool = false; } if(!oldPersonFamilyInfolist.get(i).getSFamilyIdcardNo().equals(personFamilyInfolist.get(i).getSFamilyIdcardNo())){ bool = false; } if(!oldPersonFamilyInfolist.get(i).getIFamilySex().equals(personFamilyInfolist.get(i).getIFamilySex())){ bool = false; } if(!oldPersonFamilyInfolist.get(i).getSFamilyRelation().equals(personFamilyInfolist.get(i).getSFamilyRelation())){ bool = false; } if(!oldPersonFamilyInfolist.get(i).getSFamilyInsurancePlace().equals(personFamilyInfolist.get(i).getSFamilyInsurancePlace())){ bool = false; } if(!oldPersonFamilyInfolist.get(i).getSFamilyResidencePalce().equals(personFamilyInfolist.get(i).getSFamilyResidencePalce())){ bool = false; } if(!oldPersonFamilyInfolist.get(i).getSFamilyPhone().equals(personFamilyInfolist.get(i).getSFamilyPhone())){ bool = false; } System.out.println("未更改前时间："+oldPersonFamilyInfolist.get(i).getDDentifySucessDate().getTime()); System.out.println("更改后的时间："+personFamilyInfolist.get(i).getDDentifySucessDate().getTime()); if(oldPersonFamilyInfolist.get(i).getDDentifySucessDate().getTime() != personFamilyInfolist.get(i).getDDentifySucessDate().getTime()){ bool = false; } if(bool == false){//证明字段更改过 //更新数据前，要把原来没改动的数据复制一条，添加进数据库，把系统的当前时间设为该条数据的失效时间 PersonFamilyInfo personFamilyInfo = new PersonFamilyInfo(); BeanUtils.copyProperties(oldPersonFamilyInfolist.get(i), personFamilyInfo); System.out.println("该条数据主键：" + personFamilyInfo.getSGuid()); personFamilyInfo.setSGuid(UUIDHexGenerator.getUUID()); System.out.println("设置主键：" + personFamilyInfo.getSGuid()); personFamilyInfo.setDOperateDate(new Date()); //将当前保存数据库的是否有效置为1：无效 personFamilyInfo.setIsEnable(1); personFamilyInfo.setDDentifyLostDate(new Date()); personFamilyInfoService.save(personFamilyInfo); //更新该条数据，把系统的当前时间设为系统的生效时间和操作时间，是否有效设为0：有效，失效时间为空 personFamilyInfolist.get(i).setIsEnable(0); personFamilyInfolist.get(i).setDDentifySucessDate(new Date()); personFamilyInfolist.get(i).setDOperateDate(new Date()); personFamilyInfolist.get(i).setDDentifyLostDate(null); personFamilyInfoService.merge(personFamilyInfolist.get(i)); } }catch (Exception e) { e.printStackTrace(); } } }</span>
这样，java多字段、多条数据批量添加的例子就完成了，主要要注意前台页面叠加出现多行的js函数和后台的添加和更新方法，用list接收，循环遍历进行添加。除此之外这里我想说一下下面这段代码：
复制代码 代码如下:<span>$(function(){
loadCheck();
});</span>
它就是如下代码的缩写：
复制代码 代码如下:<span> $(document).ready(function(){
loadCheck();
});</span>
其实这个代码和下面的代码是一个意思：
复制代码 代码如下:<span>window.onload=function(){
loadCheck();
}</span>
这样就不用在body的onload事件里面调用，只需要在js程序段里面编写就可以了。虽然下面的代码可以和上面两个互换，但他们之间又有不同。首先是执行时间不同，$(document).ready在页面框架下载完毕后就执行，而window.onload必须在页面全部加载完毕（包含图片下载）后才能执行。很明显前者的执行效率高于后者。再就是执行数量的不同，$(document).ready可以重复写多个，而且每次执行结果不同；而window.onload尽管可以执行多个，但仅输出最后一个执行结果，无法完成多个结果的输出。
以上就是本文的全部内容，希望对大家的学习有所帮助。
