6.pojo包下TUser类

package com.blb.ysearch.pojo;

public class TUser {
    private Integer uid;

    private String uname;

    private String upwd;

    public Integer getUid() {
        return uid;
    }

    public void setUid(Integer uid) {
        this.uid = uid;
    }

    public String getUname() {
        return uname;
    }

    public void setUname(String uname) {
        this.uname = uname;
    }

    public String getUpwd() {
        return upwd;
    }

    public void setUpwd(String upwd) {
        this.upwd = upwd;
    }
}

7.dao层

TUserMapper类：

package com.blb.ysearch.dao;

import com.blb.ysearch.pojo.TUser;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface TUserMapper {
    int deleteByPrimaryKey(Integer uid);

    int insert(TUser record);

    int insertSelective(TUser record);

    TUser selectByPrimaryKey(Integer uid);

    int updateByPrimaryKeySelective(TUser record);

    int updateByPrimaryKey(TUser record);
}

TUserMapper.xml：

xml version="1.0" encoding="UTF-8"?>
DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
mapper namespace="com.blb.ysearch.dao.TUserMapper">
  resultMap id="BaseResultMap" type="com.blb.ysearch.pojo.TUser">
    
    
    id column="uid" jdbcType="INTEGER" property="uid" />
    result column="uname" jdbcType="VARCHAR" property="uname" />
    result column="upwd" jdbcType="VARCHAR" property="upwd" />
  resultMap>
  sql id="Base_Column_List">
    
    `uid`, uname, upwd
  sql>
  select id="selectByPrimaryKey" parameterType="java.lang.Integer" resultMap="BaseResultMap">
    
    select 
    include refid="Base_Column_List" />
    from t_user
    where `uid` = #{uid,jdbcType=INTEGER}
  select>
  delete id="deleteByPrimaryKey" parameterType="java.lang.Integer">
    
    delete from t_user
    where `uid` = #{uid,jdbcType=INTEGER}

  insert id="insert" parameterType="com.blb.ysearch.pojo.TUser">
    
    insert into t_user (`uid`, uname, upwd
      )
    values (#{uid,jdbcType=INTEGER}, #{uname,jdbcType=VARCHAR}, #{upwd,jdbcType=VARCHAR}
      )
  insert>
  insert id="insertSelective" parameterType="com.blb.ysearch.pojo.TUser">
    
    insert into t_user
    trim prefix="(" suffix=")" suffixOverrides=",">
      if test="uid != null">
        `uid`,
      if>
      if test="uname != null">
        uname,
      if>

  update id="updateByPrimaryKeySelective" parameterType="com.blb.ysearch.pojo.TUser">
    
    update t_user
    set>
      if test="uname != null">
        uname = #{uname,jdbcType=VARCHAR},
      if>
      if test="upwd != null">

    set uname = #{uname,jdbcType=VARCHAR},
      upwd = #{upwd,jdbcType=VARCHAR}
    where `uid` = #{uid,jdbcType=INTEGER}
  update>

8.service层

TUserService接口类：

package com.blb.ysearch.service;

import com.blb.ysearch.pojo.TUser;

public interface TUserService {
    public void save(TUser user);
    public void remove(Integer uid);
    public void update(TUser user);
    public TUser get(Integer uid);
}

Impl包下TUserService实现类：

package com.blb.ysearch.service.impl;

import com.blb.ysearch.dao.TUserMapper;
import com.blb.ysearch.pojo.TUser;
import com.blb.ysearch.service.TUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class TUserServiceImpl implements TUserService {
    @Autowired
    private TUserMapper tUserMapper;
    @Override
    public void save(TUser user) {
        tUserMapper.insert(user);
    }

    @Override
    public void remove(Integer uid) {
        tUserMapper.deleteByPrimaryKey(uid);
    }

    @Override
    public void update(TUser user) {
        tUserMapper.updateByPrimaryKey(user);
    }

    @Transactional(readOnly = true)
    public TUser get(Integer uid) {
        TUser tUser = tUserMapper.selectByPrimaryKey(uid);
        return tUser;
    }
}

9.controller层

HelloController类：

package com.blb.ysearch.controller;

import com.blb.ysearch.pojo.TUser;
import com.blb.ysearch.service.TUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.Map;

@RestController
public class HelloController {
    @Autowired
    private TUserService tUserService;

    @RequestMapping(value = "/user/add",method = RequestMethod.POST)
    public Map add(@RequestBody TUser user){
        tUserService.save(user);
        Map map=new HashMap();
        map.put("msg","保存成功");
        map.put("status",true);
        return map;
    }

    @RequestMapping(value = "/user/{id}",method = RequestMethod.GET)
    public Map get(@PathVariable("id")Integer id){
        TUser user = tUserService.get(id);
        Map map=new HashMap();
        map.put("msg","查询成功");
        map.put("status",true);
        map.put("data",user);
        return map;
    }
}

10.根包下YsearchApplication类

package com.blb.ysearch;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class YsearchApplication {

    public static void main(String[] args) {
        SpringApplication.run(YsearchApplication.class, args);
    }

}

11.resources文件夹内application.yml

  port: 9091
spring:
  mybatis:
    mapperLocations:classpath:com/blb/ysearch/dao/*.xml
