Question

我的应用正在从csv中读取数据并插入到mysql.its中，这会占用更多的cpu。

当我在jdbc线程下进行调试时，会占用更多的CPU。

CAST(COUNT(NULLIF(C.DateChanged, 0)) * 100.0 / COUNT(NULLIF(A.LastPassedBackToSalesDate, 0)) AS numeric(18, 2)) AS PBTSbutActived

Centos

2。顶部

7435 root      20   0 7677556 366436  14528 S  86.4  4.8  67:05.60 java

有什么主意吗？

每当列表接收者收到csv时，我都会提交给Excutor服务

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();

java -AbandonedConnectionCleanupThread花了更多的cpu时间
