开发环境：系统：window7IDE:Myeclipse2014JDK版本：1.8tomcat：8maven：3.3新建SSM项目：myeclipse配置maven方式请自行百度，新建maven项目，选择webapp。新建的项目目录基本机构修改pom.xml文件这里主要是整合过程，maven的讲解就不细说了。<project xmlns="//maven.apache.org/POM/4.0.0"

com.w3cjava.pojo.User; @Componentpublic interface UserMapper { public List<User> getAllUsers(); public User findById(String id);}UserMapper对应的映射文件：UserMapper.xml映射文件UserMapper.xml所在位置在mybatis.xml文件中有配置，一般会选择配置在resources下建立mapping目录下。<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper

org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service; import com.w3cjava.dao.UserMapper;import com.w3cjava.pojo.User; @Servicepublic class UserService { @Autowired private UserMapper userMapper; public List<User> getAllUsers(){ return userMapper.getAllUsers(); } public User findById(String id){ return userMapper.findById(id); }}Controller层：package

org.springframework.web.bind.annotation.RequestMapping; import com.w3cjava.pojo.User;import com.w3cjava.service.UserService; @Controller@RequestMapping("/user")public class UserController { @Autowired

"user/userList"; } @RequestMapping(value={"add"}) public String add(){ return "user/userAdd"; } @RequestMapping(value={"edit"}) public String edit(User user){ User user2 = userService.findById(user.getId()); return "user/userEdit"; } @RequestMapping(value={"delete"}) public String delete(User user){ userService.findById(user.getId()); return "user/userList"; }
