调试intellij中的multiThreads：我怎样才能看到所有抛出的异常？ [英] debugging multiThreads in intellij: how can i see the all thrown exceptions?

问题描述

我在java中有一个多线程代码。

I have a multithreaded code in java.

我使用intellij进行调试。我知道如何在线程之间切换调试上下文。

I debug with intellij. I know how to switch debug contexts between threads.

然而，控制台只显示主线程抛出的异常。

Nevertheless the console shows only exception thrown for the main thread.

我怎样才能看到从任何线程抛出的异常？

How can i see the exceptions thrown from any thread?

基本上当我与Executor运行集成测试时，会从辅助线程抛出一些异常。

basically when I run integration test with an Executor, some exception is thrown from secondary thread.

但没有任何内容打印到调试控制台。

But nothing is printed to the debug-console.

实际上代码过得很快，而且从未到达尝试抓住我。

Actually the the code flies and never reach to the try catch i have.

这就像我抛出异常的代码之后无法继续下一步

It's like I cannot step-next after the code that throws an exception

try {
    while (true) {
        logger.debug("New thread. polling on DB, polling on deployment service");

        ConfigAction configAction = configActionFactory.get(ConfigActionsEnum.PushToDeployment);

        while (configAction != null) {
            configAction = configAction.execute() ? configAction.nextActivity() : null;
        }
    }
} catch (Exception e) {
    e.printStackTrace();
    logger.error("DeploymentContextListener run failed", e);
}

而当我使用主线程运行时，相同代码我看到异常：

whereas when I run with the main thread, the same code I see the exception:

public void run() {

    try {
        while (true) {
            logger.debug("New thread. polling on DB, polling on deployment service");

            ConfigAction configAction = configActionFactory.get(ConfigActionsEnum.PushToDeployment);

            while (configAction != null) {
                configAction = configAction.execute() ? configAction.nextActivity() : null;
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
        logger.error("DeploymentContextListener run failed", e);
    }

它写在我有的一个try-catch中

it is written in one of the try-catch i have

} catch (Exception ex) {
    logger.error("failed to get from DB: getLatestConfigVersionWaitingForDeploy", ex);
}

推荐答案

我的问题是我用过的：

 ExecutorService executor = Executors.newSingleThreadExecutor();
        executor.submit(() -> { }

来自我所读过的内容：

from what I have read:

invokeAll - 调用future.get（）。等待所有线程完成。

invokeAll - call "future.get()". Wait for all threads to finish.

提交 - >将错误附加到Future对象，而不是std-error

Submit -> attach the errors to Future objects, not the the std-error

执行 - >错误被抛出到std-error

Execute -> the errors are thrown to the std-error
