Yes, Java Spring can achieve distributed locking with Redis while allowing different timeout values for each lock. The Redisson library provides a distributed locking mechanism for Java that can be used with Spring applications. Redisson supports multiple lock types, including supports with different timeout values.
Here's an example of how to create a lock with a custom timeout using Redisson:
// Create Redisson client and RedissonLock instance
Config config = new Config();
config.useSingleServer().setAddress("redis://localhost:6379");
RedissonClient redissonClient = Redisson.create(config);
RedissonLock lock = redissonClient.getLock("myLock");
// Acquire lock with custom timeout
boolean locked = lock.tryLock(10, TimeUnit.SECONDS);
if (locked) {
try {
// Code that requires exclusive access to the resource
} finally {
lock.unlock();
}
}
In this example, the tryLock
method is used to acquire the lock with a timeout of 10 seconds. If the lock cannot be acquired within that time, the method returns false
, allowing the code to handle the failure condition appropriately. By default, Redisson locks have a timeout of 30 seconds, but this can be customized as needed.
