spring-boot使用tools-redis实现分布式锁

1.在pom文件中导入tools-redis

cn.gjingtools-redis1.0.0

2.在application.properties文件中添加redis连接

#redis数据库链接配置spring.redis.host=127.0.0.1spring.redis.port=6379spring.redis.password=spring.redis.database=0

3.在DemoApplication.java中添加

@EnableRedisLock

4.编写一个例子给到

4.1创建DemoController

@RestControllerpublic class DemoController {@Autowiredprivate DemoService demoService;@GetMapping("demo")public boolean demo(){return demoService.demo();}}

4.2创建DemoService

@Servicepublic class DemoService {private static Integer thread=20;@Lock(key = "demo")public boolean demo(){System.out.println("当前线程:"   Thread.currentThread().getName() "未消费：" thread);if(thread==0) {System.out.println("消费完成"); return true;}--thread;return false;}}

5.测试
