多重コード系列:Redisson+SpringBootに基づくRedis分散ロック

コード系列ディレクトリの多重化
分散ロックインタフェースの定義

package com.redis.lock.redisson_springboot;

import java.util.concurrent.TimeUnit;

public interface DistributedLocker {

    void lock(String lockKey);

    void unlock(String lockKey);

    void lock(String lockKey, int timeout);
    
    void lock(String lockKey, TimeUnit unit ,int timeout);
}

Redissonベースの分散ロック実装

package com.redis.lock.redisson_springboot;

import org.redisson.api.RLock;
import org.redisson.api.RedissonClient;

import java.util.concurrent.TimeUnit;

public class RedissonDistributedLocker implements DistributedLocker {
    
    private RedissonClient redissonClient;

    @Override
    public void lock(String lockKey) {
        RLock lock = redissonClient.getLock(lockKey);
        lock.lock();
    }

    @Override
    public void unlock(String lockKey) {

        lock.unlock();
    }

        lock.lock(leaseTime, TimeUnit.SECONDS);
    }
