类 RedisTemplateSimpleDistributedLock

java.lang.Object

me.chanjar.weixin.common.util.locks.RedisTemplateSimpleDistributedLock

所有已实现的接口:

Lock

public class RedisTemplateSimpleDistributedLock
extends Object
implements Lock

实现简单的redis分布式锁, 支持重入, 不是红锁

另请参阅:

reids distlock

构造器概要

构造器

构造器和说明
RedisTemplateSimpleDistributedLock(@NonNull org.springframework.data.redis.core.StringRedisTemplate redisTemplate, int leaseMilliseconds)
RedisTemplateSimpleDistributedLock(@NonNull org.springframework.data.redis.core.StringRedisTemplate redisTemplate, @NonNull String key, int leaseMilliseconds)

方法概要

限定符和类型	方法和说明
String	getLockSecretValue() 获取当前锁的值 return 返回null意味着没有加锁, 但是返回非null值并不以为着当前加锁成功(redis中key可能自动过期)
void	lock()
void	lockInterruptibly()
Condition	newCondition()
boolean	tryLock()
boolean	tryLock(long time, TimeUnit unit)
void	unlock()

从类继承的方法 java.lang.Object
