# distributed-redission

#### 介绍
redission分布式锁

#### 使用说明

1.  yml文件配置 
yu.redisson.lock.server.address；#127.0.0.1:6379
yu.redisson.lock.server.type；#接类型，支持standalone-单机节点，sentinel-哨兵，cluster-集群，masterslave-主从
yu.redisson.lock.server.password；
yu.redisson.lock.server.database；#选取那个数据库
yu.redisson.lock.server.port；
2.  service方法上使用@DistributedLock注解,leaseTime 代表租期，默认10s，单位：秒
例：@DistributedLock(value = "redis-key-", leaseTime = 10)
3.  可搭配@LockParameter注解进一步缩小锁粒度，该注解用在参数前
4. 完整实例如下
@Controller
@Slf4j
public class LockController {

    @Autowired
    private LockService lockService ;
     @RequestMapping(value = "/test")
    public Boolean test(String name）{
        //调用
        String userId="10001";
        lockService.testMethod(userId,name);
    }
} 
-------------------------------------------------------------------------
@Service
@Slf4j
public class LockService {
     @DistributedLock(value = "redis-key-", leaseTime = 10)
    public Boolean testMethod(@LockParameter String userId，String name）{
        //do something------
    }
} 

-------------------------------------------------------------------------
实际redis的key  ：redis-key-10001
