1、MySQL方面，已经准备好了存储过程，参考：MYSQL存储过程（含入参、出参）-CSDN博客

2、pom.xml文件内容如下：

3、application.yml文件内容如下：

server:
  port: 8081
  servlet.context-path: /

#配置数据源
spring:
  datasource:
    druid:
      db-type: com.alibaba.druid.pool.DruidDataSource
      driverClassName: net.sf.log4jdbc.sql.jdbcapi.DriverSpy
      url: jdbc:log4jdbc:mysql://${DB_HOST:localhost}:${DB_PORT:3306}/${DB_NAME:eladmin}?serverTimezone=Asia/Shanghai&characterEncoding=utf8&useSSL=false
      username: ${DB_USER:root}
      password: ${DB_PWD:demo}
  redis:
    host: localhost
    port: 6379
    password: demo
    database: 10
  data:
    mongodb:
      host: 43.138.0.199
      port: 27017
      username: hmblogs
      password: demo
      database: hmblogs
      authentication-database: admin

es:
  host: 43.138.0.199
  port: 9200
  scheme: http
  user: elastic
  password: demo

4、BackendApplication文件内容如下：

package com.hmblogs.backend;

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

@SpringBootApplication
public class BackendApplication {

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

}

5、StockMapper.xml文件内容如下：

<?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.hmblogs.backend.dao.StockMapper">
    <resultMap id="BaseResultMap" type="com.hmblogs.backend.entity.Stock">
        <id column="id" property="id"/>
        <result column="quantity" property="quantity"/>
    </resultMap>

    <sql id="BaseResultMap">
        id, quantity
    </sql>

    <select id="findAll" resultMap="BaseResultMap">
        select
        <include refid="BaseResultMap"/>
        from t_stock

    </select>

    <select id="findById" resultMap="BaseResultMap"  parameterType="com.hmblogs.backend.entity.Stock">
        select
        <include refid="BaseResultMap"/>
        from t_stock
        where id=#{id}
    </select>

    <update id="updateStockById" parameterType="com.hmblogs.backend.entity.Stock">
        update t_stock set quantity=quantity-1 where id=#{id}
    </update>

    <select id="invokeStockProdudure" statementType="CALLABLE" parameterType="java.util.Map" resultType="java.util.Map">
        CALL stock_produdure(
            #{id1,mode=IN,jdbcType=INTEGER},
            #{quantity1,mode=IN,jdbcType=INTEGER},
            #{id2,mode=IN,jdbcType=INTEGER},
            #{quantity2,mode=IN,jdbcType=INTEGER},
            #{result,mode=OUT,jdbcType=INTEGER}
            );
    </select>

</mapper>

6、StockMapper文件内容如下：

package com.hmblogs.backend.dao;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.hmblogs.backend.entity.Stock;
import org.apache.ibatis.annotations.Mapper;

import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Mapper
public interface StockMapper extends BaseMapper<Stock> {
    List<Stock> findAll();

    Stock findById(Stock stock);

    Integer updateStockById(Stock stock);

    Map<String,Integer> invokeStockProdudure(Map<String,String> param);
}

7、Stock文件内容如下：

package com.hmblogs.backend.entity;


import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

@Data
@TableName("t_stock")
public class Stock {

    @TableId(value="id", type = IdType.AUTO)
    private Integer id;

    private Integer quantity;

}

8、StockServiceImpl代码如下：

package com.hmblogs.backend.service;

import com.hmblogs.backend.dao.StockMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

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

@Slf4j
@Service
public class StockServiceImpl {

    @Autowired
    private StockMapper stockMapper;

    public void operateProcedure(){
        HashMap<String,String> param = new HashMap<>();
        param.put("id1","7000");
        param.put("quantity1","15");
        param.put("id2","7001");
        param.put("quantity2","18");
        Map<String,Integer> result = stockMapper.invokeStockProdudure(param);
        log.info("result:"+result);
    }
}

9、测试类ProcedureTest内容如下：

package com.hmblogs.backend.util;

import com.hmblogs.backend.service.StockServiceImpl;
import lombok.extern.slf4j.Slf4j;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

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

@Slf4j
//@Component
@RunWith(SpringRunner.class)
@SpringBootTest
public class ProcedureTest {

    @Autowired
    private StockServiceImpl stockServiceImpl;

    @Test
    public void testProcedure() {
        // 请求参数
        stockServiceImpl.operateProcedure();
    }
}

执行该方法，

查看数据：

10、StockServiceImpl内代码改动一下，

执行测试方法，结果如下：

查看数据，没有id为8000的记录
