工作中SpringBoot经常要用到redis分布式锁，比如更改金额，spring integration redis提供了解决方案，以下是使用步骤。
maven引入spring-integration-redis

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-redis</artifactId>
    <version>5.3.1.RELEASE</version>
</dependency>

定义RedisLockRegistry Bean

@Bean(destroyMethod = "destroy")
public RedisLockRegistry redisLockRegistry(RedisConnectionFactory redisConnectionFactory) {
     return new RedisLockRegistry(redisConnectionFactory, “app_name_lock_registry”);
}

业务代码中使用，

@Autowired
private RedisLockRegistry redisLockRegistry;

Lock lock = redisLockRegistry.obtain("lock_prefix" + id);
 try {
     boolean got = lock .tryLock(1L, SECONDS);
      if(!got){
          throw new RuntimeException(msg);
      }
  } catch (InterruptedException e) {
     throw new RuntimeException(msg);
  }
try{
 //业务逻辑
}catch(Exception e){

}finally{
	lock.unlock();
}
