SpringBoot分布式锁ShedLock

一、分布式锁配置

（1）redis锁

@Configuration
@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "PT30S")
public class DataSourceConfig {@Beanpublic LockProvider scheduledLockConfiguration(@Autowired RedisConnectionFactory connectionFactory) {return new RedisLockProvider(connectionFactory);}}

（2）数据库锁

@Configuration
@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "PT30S")
public class DataSourceConfig {@Beanpublic scheduledLockConfiguration(@Autowired DataSource dataSource) {return new JdbcTemplateLockProvider(dataSource);}}

二、定时任务配置

@Component
public class CronTask {@Scheduled(cron="0 0/1 * * * ?")@SchedulerLock(name = "test-lock:testMethod", lockAtMostFor = 3 * 60 * 1000, lockAtLeastFor = 30 * 1000)public void testMethod(){//do something}}
