      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：

    
        
        
    

    
        id, quantity
    

    
        select
        
        from t_stock

    

    
        select
        
        from t_stock
        where id=#{id}
    

    
        update t_stock set quantity=quantity-1 where id=#{id}
    

    
        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}
            );
    

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 {
    List findAll();

    Stock findById(Stock stock);

    Integer updateStockById(Stock stock);

    Map invokeStockProdudure(Map 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 param = new HashMap<>();
        param.put("id1","7000");
        param.put("quantity1","15");
        param.put("id2","7001");
        param.put("quantity2","18");
        Map 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
