java - java -AbandonedConnectionCleanupThread 占用更多 CPU 时间

Question

我的应用程序正在从 csv 读取数据并插入 mysql.its 占用更多 CPU。

当我在 jdbc 下调试时，线程占用了更多的 cpu。

com.mysql.jdbc.AbandonedConnectionCleanupThread.run(AbandonedConnectionCleanupThread.java:40)

任何想法？

ExecutorService service=Executors.newFixedThreadPool(count);
            FileAlterationObserver fao = new FileAlterationObserver(folder);
            fao.addListener(new FileListener(service));
            final FileAlterationMonitor monitor = new FileAlterationMonitor(Integer.parseInt("100"));
            monitor.addObserver(fao);
            monitor.start();

每当listner收到csv时，我都会提交给Excutor服务

service.submit(new PerformanceFileReader(f));
