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">

      )
  </insert>
  <insert id="insertSelective" parameterType="com.blb.ysearch.pojo.TUser">
    <!--@mbg.generated-->

    <trim prefix="values (" suffix=")" suffixOverrides=",">
      <if test="uid != null">
        #{uid,jdbcType=INTEGER},
      </if>
      <if test="uname != null">

      </if>
      <if test="upwd != null">
        #{upwd,jdbcType=VARCHAR},

  </update>
  <update id="updateByPrimaryKey" parameterType="com.blb.ysearch.pojo.TUser">
    <!--@mbg.generated-->

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

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

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