Springboot 集成Mybatis 增删改查使用XML

基于 https://www.cnblogs.com/suphowe/p/13152087.html 进行修改

一、修改XML配置

src\main\resources\mapper\TestMapper.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.soft.dao.MybatisTestMapper">

    <select id="findAll" resultType="com.soft.entity.Test">
        select * from sys_test
    </select>

    <select id="findByName" resultType="com.soft.entity.Test">
        select * from sys_test where name=#{name}
    </select>

    <insert id="insertSysTest" parameterType="com.soft.entity.Test">
        insert into sys_test (id, user, name, tel) values (#{id},#{user},#{name},#{tel})
    </insert>

    <update id="updateSysTest" parameterType="com.soft.entity.Test">
        update sys_test set user=#{user},name=#{name},tel=#{tel} where id=#{id}
    </update>

    <delete id="deleteSysTest" parameterType="com.soft.entity.Test">
        delete from sys_test where id=#{id}
    </delete>
</mapper>

二、修改Java代码

MybatisTestMapper.java

package com.soft.dao;

import com.soft.entity.Test;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Component;

import java.util.List;

@Mapper
@Component
public interface MybatisTestMapper {

    List<Test> findAll();

    List<Test> findByName(Test test);

    int insertSysTest(Test test);

    int updateSysTest(Test test);

    int deleteSysTest(Test test);
}

MybatisTestServiceImpl.java

package com.soft.service.impl;

import com.soft.dao.MybatisTestMapper;
import com.soft.entity.Test;
import com.soft.service.IMybatisServiceTest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.HashMap;
import java.util.List;

@Service
public class MybatisTestServiceImpl implements IMybatisServiceTest {

    @Autowired
    private MybatisTestMapper mybatisTestMapper;

    @Override
    public List<Test> findAll() {
        return mybatisTestMapper.findAll();
    }

    @Override
    public List<Test> findByName(String name) {
        Test test = new Test();
        test.setName(name);
        return mybatisTestMapper.findByName(test);
    }

    @Override
    public HashMap<String, Object> insertSysTest(int id, String user, String name, String tel) {
        Test test = new Test();
        test.setId(id);
        test.setUser(user);
        test.setName(name);
        test.setTel(tel);
        int result = mybatisTestMapper.insertSysTest(test);
        HashMap<String, Object> returnMap = new HashMap<>(1);
        returnMap.put("count", result);
        return returnMap;
    }

    @Override
    public HashMap<String, Object> updateSysTest(int id, String user, String name, String tel) {
        Test test = new Test();
        test.setId(id);
        test.setUser(user);
        test.setName(name);
        test.setTel(tel);
        int result = mybatisTestMapper.updateSysTest(test);
        HashMap<String, Object> returnMap = new HashMap<>(1);
        returnMap.put("count", result);
        return returnMap;
    }

    @Override
    public HashMap<String, Object> deleteSysTest(int id) {
        Test test = new Test();
        test.setId(id);
        int result = mybatisTestMapper.deleteSysTest(test);
        HashMap<String, Object> returnMap = new HashMap<>(1);
        returnMap.put("count", result);
        return returnMap;
    }
}

IMybatisServiceTest.java

package com.soft.service;

import com.soft.entity.Test;

import java.util.HashMap;
import java.util.List;

public interface IMybatisServiceTest {

    List<Test> findAll();

    List<Test> findByName(String name);

    HashMap<String, Object> insertSysTest(int id, String user, String name, String tel);

    HashMap<String, Object> updateSysTest(int id, String user, String name, String tel);

    HashMap<String, Object> deleteSysTest(int id);
}

MybatisTestController.java

package com.soft.controller;

import com.soft.entity.Test;
import com.soft.service.IMybatisServiceTest;
