Spring集成JDBC锁CannotAcquireLockException

编程问答 2022-05-22

问题描述

我观察到以下异常。这是错误还是预期？我应该处理这个异常吗？

使用的版本：spring-integration-jdbc：5.4.2 数据库：Oracle 12c 服务器：Tomcat 9

以下是 bean 的实例化方式。

@Bean
public DefaultLockRepository defaultLockRepository(@Value("${table.prefix}") String prefix,@Value("${distributed.lock.ttl}") int ttl) {
    DefaultLockRepository repository = new DefaultLockRepository(imexDataSource());
    repository.setPrefix(prefix);
    repository.setTimetoLive(ttl);
    return repository;
}

@Bean
public JdbcLockRegistry jdbcLockRegistry(LockRepository lockRepository) {
    return new JdbcLockRegistry(lockRepository);
}

以下是我使用 API 的方式

@Bean
@ConditionalOnProperty(value = "generic.cron.email.notification.enabled",matchIfMissing = false,havingValue = "true")
public MyService myService(SomeService someService) {
    return new MyService(){

        @Scheduled(cron="${generic.cron.email.notification.expression}")
        @Override
        public void sendEmailAlerts() {
            log.debug("Attempting lock.obtain");
            Lock lock = lockRegistry.obtain("EMAIL_ALERT");
            if(Objects.isNull(lock)){
                log.warn("Received null lock");
                return;
            }
            boolean locked = false;
            try {
                locked = lock.tryLock();
                if(locked){
                    log.debug("Obtained lock");
                    someService.doSomething();
                }else {
                    log.debug("Unable to obtain lock");
                }
            } finally {
                if(locked){
                    log.debug("Releasing lock");
                    lock.unlock();
                }
            }
        }
    };
}

引发了以下异常。请注意，这仅发生一次，并且不经常发生。请查看代码并建议是否应使用该 API。还请告诉我这是否是 API 的预期行为，我们必须处理并忽略它。
