Tomcat,Spring,Schedulers - 内存泄漏

标签: java spring tomcat memory-leaks spring-scheduled

我有一些类使用Scheduled annotation注释方法。

当我在Tomcat中停止/取消部署/重新部署此应用程序时,我收到了这样的消息:

"The following web applications were stopped (reloaded, undeployed), but their classes from previous runs are still loaded in memory, thus causing a memory leak (use a profiler to confirm):
/my-app
/my-app
/my-app"

我已经尝试过" autowire" ContextClosed处理程序中的ThreadPoolTask​​Executor并使用shutdown()方法将其停止。但它没有任何帮助。似乎预定的方法(线程)不受Tomcat控制。

我也尝试过设置taskExecutor.setWaitForTasksToCompleteOnShutdown(false)。

当我获得堆的转储时,我只看到包含Scheduled方法和与之关联的类的类(实例)。

这会导致我们的服务器()在几天内停止响应请求时出现问题。

配置:

@Configuration
@EnableWebMvc
@EnableScheduling
public class AppConfig {
    @Bean
    public ThreadPoolTaskScheduler taskScheduler(){
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(20);
        executor.setMaxPoolSize(40);
        executor.setQueueCapacity(400);
        executor.setWaitForTasksToCompleteOnShutdown(false);
        executor.initialize();

        return executor;
    }
}

调度程序:

@Component
public class HistoryCleaner {

    @Autowired
    private HistoryService historyService;
    @Autowired
    private AppProperties app;

    @Scheduled(fixedDelay = 10000)
    public void cleanHistory() {
        ...
    }
}
