本文已参与「新人创作礼」活动，一起开启掘金创作之路
在昨天实现查找的基础上实现增、删、改。并实现分页操作。此处不再给出结构，可参看上一篇博客
效果图
一、准备工作
导入架包 在pom.xml中加上下面这段
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>5.1.2</version>
</dependency>
修改resources中的applicationContext.xml
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource"/>
<!-- 扫描bean包 使用别名 -->
<property name="typeAliasesPackage" value="com.zhongruan.bean"></property>
<!--配置加载映射文件 UserMapper.xml-->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<props>
<prop key="helperDialect">mysql</prop>
<prop key="reasonable">true</prop>
</props>
</property>
</bean>
</array>
</property>
</bean>
二、增加用户
IUserInfoDao
void add(UserInfo userInfo);//添加方法
UserMapper.xml
<insert id="add" parameterType="com.zhongruan.bean.UserInfo">
insert into userinfo(name,password) values(#{name},#{password})
</insert>
IUserInfoService
void add(UserInfo userInfo);
UserInfoServiceImpl
public void add(UserInfo userInfo) {
userInfoDao.add(userInfo);
}
UserInfoController
@RequestMapping("/add.do")
public String add(UserInfo userInfo){
userInfoService.add(userInfo);
return "redirect:findAll.do";
}
user-list.jsp部分
<button type="button" class="btn btn-default" title="新建"
onclick="location.href='${pageContext.request.contextPath}/pages/user-add.jsp'" >
<i class="fa fa-file-o"></i> 新建
</button>
user-add.jsp部分
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8" isELIgnored="false"%>

if (liObj.length > 0) {
liObj.parent().parent().addClass("active");
liObj.addClass("active");
}
}
</script>
</body>
</html>
三、删除
IUserInfoDao
void delete(int id);//删除
UserMapper.xml
<delete id="delete" parameterType="int">
delete from userinfo where id=#{id}
</delete>
IUserInfoService
void delete(int id);//删除
UserInfoServiceImpl
@Override
public void delete(int id) {
userInfoDao.delete(id);
}
user-list
<a href="${pageContext.request.contextPath}/user/delete.do?id=${user.id}" class="btn bg-olive btn-xs">删除</a>
三、更新
首先要有一个toupdate方法，用于页面的跳转和传值（id），然后编写findUserById方法，用于查询到需要修改的对象，传给Update方法修改。
1.首先实现findUserById方法 在IUserInfoDao中添加方法
UserInfo findUserById(int id);
UserMapper.xml中实现方法
<select id="findUserById" resultType="com.zhongruan.bean.UserInfo" parameterType="int">
select * from userinfo where id=#{id}
</select>
IUserInfoService
UserInfo findUserById(int id);
UserInfoServiceImpl
@Override
public UserInfo findUserById(int id) {
return userInfoDao.findUserById(id);
}
2.toUpdate方法的实现，在UserInfoController中添加
@RequestMapping("toUpdate.do")
public ModelAndView toUpdate(int id){
UserInfo user=userInfoService.findUserById(id);
ModelAndView mv =new ModelAndView();
mv.addObject("user",user);
mv.setViewName("user-update");
return mv;
}
user-list.jsp修改
<a href="${pageContext.request.contextPath}/user/toUpdate.do?id=${user.id}" class="btn bg-olive btn-xs">更新</a>
user-update.jsp获取到对象，让用户可在该页面修改，然后传至update方法处理

if (liObj.length > 0) {

</body>
</html>
3.update方法的实现 IUserInfoDao
public void update(UserInfo userInfo);
UserMapper.xml
<update id="update" parameterType="com.zhongruan.bean.UserInfo">
update userinfo set name=#{name},password=#{password} where id=#{id}
</update>
IUserInfoService
void update(UserInfo userInfo);
UserInfoServiceImpl
@Override
public void update(UserInfo userInfo) {
userInfoDao.update(userInfo);
}
UserInfoController
@RequestMapping("update.do")
public String Update(UserInfo userInfo){
userInfoService.update(userInfo);
return "redirect:findAll.do";
}
四、分页
在上一篇的基础上修改了以下几点 IUserInfoService
public List<UserInfo> findAll(int page,int size);
UserInfoServiceImpl
@Override
public List<UserInfo> findAll(int page,int size) {
PageHelper.startPage(page,size);
return userInfoDao.findAll();
}
UserInfoController
@RequestMapping("/findAll.do")
public ModelAndView findAll(@RequestParam(defaultValue = "1")int page,@RequestParam(defaultValue = "5")int size){//默认参数是1和5
List<UserInfo> userInfos = userInfoService.findAll(page,size);
PageInfo pageInfos=new PageInfo(userInfos);
ModelAndView mv =new ModelAndView();
mv.addObject("pageInfos",pageInfos);
mv.setViewName("user-list");
return mv;
}
