3，建立表和初始化資料

CREATE TABLE `order_info` (

`id` int(11) NOT NULL COMMENT '主鍵ID',

`num` int(11) NOT NULL COMMENT '庫存',

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=latin1;

INSERT INTO order_info VALUES(1,100)

4，編寫程式碼

4.1 配置redis連線

package com.dream21th.redisson.config;

import org.redisson.Redisson;
import org.redisson.api.RedissonClient;
import org.redisson.config.Config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/*
 * @Author dream21th
 **/
@Configuration
public class RedissionConf {

    @Bean
    public RedissonClient redission(){
        Config config = new Config();
        config.useSingleServer().setAddress("redis://127.0.0.1:6379");
        RedissonClient redisson = Redisson.create(config);
        return redisson;
    }

}

4.2 配置mybatis

package com.dream21th.redisson.config;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Configuration;

/*
 * @Author dream21th
 **/
@Configuration
@MapperScan("com.dream21th.redisson.mapper*")
public class MyBatisConfig {
}

4.3編寫實體類

package com.dream21th.redisson.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 com.baomidou.mybatisplus.extension.activerecord.Model;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

/*
 * @Author dream21th
 **/
@Data
@TableName("order_info")
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class Order extends Model<Order> {

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

    @TableField(value = "num")
    private Integer num;

    @Override
    protected Serializable pkVal() {
        return this.id;
    }
}

4.4編寫mapper類

package com.dream21th.redisson.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.dream21th.redisson.entity.Order;

/*
 * @Author dream21th
 **/
public interface OrderMapper extends BaseMapper<Order> {
}

4.5編寫controller

package com.dream21th.redisson.controller;

import com.dream21th.redisson.entity.Order;
import com.dream21th.redisson.mapper.OrderMapper;
import lombok.extern.slf4j.Slf4j;
import org.redisson.api.RLock;
import org.redisson.api.RedissonClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/*
 * @Author dream21th
 **/
@Slf4j
@RestController
public class TestController {

    @Autowired
    private OrderMapper orderMapper;

    @Autowired
    private RedissonClient redisson;

    @GetMapping("testKill")
    public void testKill(){
        RLock lock = redisson.getLock("KILL-LOCK");
        lock.lock();
        try{
            Order order = orderMapper.selectById(1);
            if(order.getNum()==0){
                log.info("------------------->>>{}沒有庫存了<<<------------------",Thread.currentThread().getId());
            }else {
                log.error("搶到庫存還是剩：{}",order.getNum());
                order.setNum(order.getNum()-1);
                orderMapper.updateById(order);
            }
        }finally {
            lock.unlock();
        }
    }
}

5，測試準備

5.1開啟jmter（準備兩個）

壓力測試8081埠（10個執行緒執行10次）

5.2啟動應用分別（埠：8080,8081）

6，開始測試

6.1分別啟動兩個jmter

7，測試結果

8080埠執行結果
