前一篇文章说了怎么使用tkmybatis中给我们提供的CRUD接口，直接调用即可，但是很多情况下提供的接口并不满足所有需求，那么就需要我们自己配置xml文件了

UserController：

@RestController
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/findById/{id}")
    public User findById(@PathVariable int id) {
        User user = userService.findById(id);
        return user;
    }

    @RequestMapping("/findAll")
    public List<User> findAll() {
        List<User> userList = userService.findAll();
        return userList;
    }

    @RequestMapping("/insert")
    public void insert() {
        User user = new User();
        user.setName("张三");
        user.setSex("男");
        user.setAge(18);
        user.setAddress("江西省");
        user.setPhone("456789645");
        userService.insert(user);
    }

    @RequestMapping("/delete")
    public void delete() {
        User user = new User();
        user.setId(5);
        userService.delete(user);
    }

    @RequestMapping("/update")
    public void update() {
        User user = new User();
        user.setId(5);
        user.setName("李四");
        userService.update(user);
    }
}

UserService：

public interface UserService {

    public User findById(int id);

    public List<User> findAll();

    public void insert(User user);

    public void update(User user);

    public void delete(User user);

}

UserServiceImpl：

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public User findById(int id) {
        return userMapper.selectUserById(id);
    }

    @Override
    public List<User> findAll() {
        return userMapper.selectUserList();
    }

    @Override
    public void insert(User user) {
        userMapper.insertUser(user);
    }

    @Override
    public void update(User user) {
        userMapper.updateUser(user);
    }

    @Override
    public void delete(User user) {
        userMapper.deleteUser(user);
    }
}

UserMapper：

public interface UserMapper extends Mapper<User> {

    public void insertUser(User user);

    public void updateUser(User user);

    public void deleteUser(User user);

    public User selectUserById(int id);

    public List<User> selectUserList();
}

UserMapper.xml：

<mapper namespace="com.wyj.mapper.UserMapper">

    <insert id="insertUser" parameterType="com.wyj.entity.po.User">
        insert into `user`(name,sex,age,address,phone) values (#{name},#{sex},#{age},#{address},#{phone})

    <delete id="deleteUser" parameterType="com.wyj.entity.po.User">
        delete from `user` where id=#{id}
    delete>

    <select id="selectUserById" parameterType="java.lang.Integer" resultType="com.wyj.entity.po.User">
        select id,name,sex,age,address,phone from `user` where id=#{id}
