创建项目此处不赘述了，自行熟悉一下哦。
项目结构
注意：这种项目上偶尔有个小红x，出现时在项目上右键--maven--更新项目即可。
看看配置文件（注意观察mybatis的配置及文件所在位置）

package com.wl.controller;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.bind.annotation.RestController;import com.wl.domain.TestUser;import com.wl.service.TestUserService;@RestController@RequestMapping("/testuser")public class TestUserController { @Autowired private TestUserService testUserService; //http://localhost:8888//LANW2.0/testuser/hello// @RequestMapping(value = {"/hello"},produces = {"application/json;charset=UTF-8"},method = RequestMethod.GET) @RequestMapping("hello") public String hello() { return "nihao!!!"; } //http://localhost:8888//LANW2.0/testuser/selectAll // @GetMapping(value="/selectAll") @RequestMapping(value = {"/selectAll"},produces = {"application/json;charset=UTF-8"},method = RequestMethod.GET) @ResponseBody public List findAllUser(){ return testUserService.findAllUser(); } //测试插入http://localhost:8888//LANW2.0/testuser/testinsert @RequestMapping(value = {"/testinsert"},produces = {"application/json;charset=UTF-8"},method = RequestMethod.GET) @ResponseBody public List testinsert(){ TestUser u = new TestUser("同学3","地址3"); testUserService.testInsert(u); return testUserService.findAllUser(); }}Service及其实现类
package com.wl.service;import java.util.List;import com.wl.domain.TestUser;public interface TestUserService {List findAllUser();void testInsert(TestUser u);}注意：Service注解在实体类上，且必须加上
package com.wl.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.wl.domain.TestUser;import com.wl.mapper.TestUserMapper;import com.wl.service.TestUserService;@Service(value = "testUserService")public class TestUserServiceImpl implements TestUserService{ @Autowired private TestUserMapper userDao;//这里可能会报错，但是并不会影响 public List findAllUser(){return userDao.findAllUser(); }@Overridepublic void testInsert(TestUser u) {userDao.testInsert(u);}}Dao
package com.wl.mapper;import java.util.List;import org.apache.ibatis.annotations.Mapper;import com.wl.domain.TestUser;@Mapperpublic interface TestUserMapper { //测试插入 public void testInsert(TestUser u); //列表 public List findAllUser();}userMapper接口对应的xml文件
insert into testuser(name,address) values(#{name},#{address})select * from testuser欧了，到此所有需要的代码都为你准备好了，还等什么呢，自己试试呗~_~
