根据所需要的可以对上面的进行删减

配置事务管理器 application-transaction.xml (Spring配置）

配置SpringMVC文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd "><!-- 配置扫描器，扫描注解包 ,注意：这里扫描包只扫描SpringMVC所用到的包即可，如 controller包，否则会与spring配置的扫描器发生冲突引起错误--><context:component-scan base-package="com.mingde.controller" /><!-- 配置映射和适配 --><mvc:annotation-driven /><!-- 配置响应跳转页面 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/st/" /><property name="suffix" value=".jsp" /></bean></beans>

配置MyBatis文件

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><!-- 配置别名 --><typeAliases><package name="com.mingde.po"/></typeAliases><!-- 配置映射sql语句的文件，扫描整个mapper包 --><mappers><package name="com.mingde.mapper"/></mappers></configuration>

配置Mapper.xml和接口

注意：接口要与mapper.xml配置文件写在同一个mapper包中，并且二者的文件名称要完全相同

接口

package com.mingde.mapper;import java.util.List;import org.apache.ibatis.annotations.Param;import com.mingde.po.Student;public interface StudentMapper {//查询所有学生信息public List<Student> list()throws Exception;//模糊查询所有学生信息public List<Student> find(Student st)throws Exception;//删除学生信息public void delete(int sid)throws Exception;//若有2个参数则要写参数的名称,比如说：要参数1班编号为1001的学生public void deleteByCidAndSid(@Param("cid")int cid,@Param("sid")int sid )throws Exception;}

Mapper.xml配置

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.mingde.mapper.StudentMapper"> <!-- 这里的namespace要写接口的全路径和名称 --><resultMap type="Student" id="Students"><id column="sid" property="sid" /><association column="cid" property="classes" select="findClasses"  ></association></resultMap><select id="findClasses" resultType="Classes" parameterType="int"  >select * from Classes where cid=#{cid}</select><!-- id的名称要与接口对应的方法一致 ，并且返回类型也要和接口的返回类型一致，参数类型可写可不写 --><!-- 查询所有学生信息 --><select id="list" resultMap="Students">select * from Student</select><!-- 模糊查询 --><select id="find" resultMap="Students" parameterType="Student" >select * from Student <where><if test="sname!=null "> and sname like '%${sname}%'</if><if test="sex!=null and sex!='不限' "> and sex=#{sex}</if></where></select><!-- 删除指定学生信息 --><delete id="delete" parameterType="int" >delete from Student where sid=#{value}</delete><!-- 根据班级编号和学生编号来删除学生信息 --><delete id="deleteByCidAndSid"><!-- 这个的#{cid}和#{sid}是根据接口定义的@Param("cid")和@Param("sid")来决定的，不可乱写 -->delete from Student where cid=#{cid} and sid=#{sid}</delete></mapper>

定义service来实现代替操作和被事务管理

StudentService

package com.mingde.service;import java.util.List;import com.mingde.po.Student;public interface StudentService {//这里的方法和在mapper包中的StudentMapper.java一样，当然也可以根据自己所有状况改变，如分页的时候就不能完全一样public List<Student> list()throws Exception;public List<Student> find(Student st)throws Exception;public void delete(int sid)throws Exception;}

StudentServiceImpl

package com.mingde.service.impl;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.mingde.mapper.StudentMapper;import com.mingde.po.Student;import com.mingde.service.StudentService;//将该类放入bean工厂中，名字定为‘ss’,在任何类中可以直接根据该名称取出该bean@Service("ss")public class StudentServiceImpl implements StudentService {//这里将mapper包中的StudentMapper.java类拿来，把首字母改为小写就可引用bean工厂里的studentMapper//因为在application-dao.xml中已将mapper包中所有的的类和xml文件进行扫描映射，然后将其映射到bean工厂中，名称为该类的名称，然后首字母小写//为该类进行实例化，实例化后，可以用该类的所有方法@Resource(name="studentMapper")StudentMapper sm;public List<Student> list() throws Exception {return sm.list();}public List<Student> find(Student st) throws Exception {return sm.find(st);}public void delete(int sid) throws Exception {sm.delete(sid);Student st=null;System.out.println(st.getAddr());}}

控制层controller

package com.mingde.controller;import javax.annotation.Resource;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.mingde.po.Student;import com.mingde.service.StudentService;@Controller@RequestMapping("st")public class StudentController {//引用放入bean工厂里的StudentServiceImpl，将其实例化给StudentService@Resourceprivate StudentService ss;@RequestMapping("list")public ModelAndView list()throws Exception{return new ModelAndView("list","st",ss.list()); //转发：方法一}@RequestMapping("search")public String search(Model model,Student st)throws Exception{model.addAttribute("st",ss.find(st));return "list";//转发：方法二}@RequestMapping("delete")public String delete(int sid)throws Exception{ss.delete(sid);return "redirect:list.action"; //重定向}}

JSP页面省略
