ShedLock

ShedLock是一个用于分布式任务调度的开源库。

它提供了一种简单而可靠的方式来确保在分布式环境中只有一个节点执行指定的任务。

对接ShedLock命令参考如下。

import com.huawei.devspore.mas.redis.core.MultiZoneClient;
import com.huawei.devspore.mas.redis.spring.boot.cache.DcsConnectionFactory;
import net.javacrumbs.shedlock.core.LockProvider;
import net.javacrumbs.shedlock.provider.redis.spring.RedisLockProvider;
import net.javacrumbs.shedlock.spring.annotation.EnableSchedulerLock;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;

@Configuration
@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "PT30S")
public class ShedLockJdbcConfig {
    @Bean
    public DcsConnectionFactory dcsConnectionFactory(MultiZoneClient client) {
        return new DcsConnectionFactory(client);
    }

    @Bean
    public LockProvider lockProvider(DcsConnectionFactory connectionFactory) {
        return new RedisLockProvider(connectionFactory);
    }
}
