JAVA 并发线程异常处理

线程中如果有未处理的异常, 放在try catch模块里可能会捕获不到.?

此处有个解决方法

?

?

class MyUncaughtExceptionHandler implements

Thread.UncaughtExceptionHandler{

public void uncaughtException(Thread t, Throwable e) {

System.out.println("caught " + e); ?//此处捕获线程中出现的异常

}

}

?

class HandlerThreadFactory implements ThreadFactory{

public Thread newThread(Runnable r) {

Thread t = new Thread(r);

t.setUncaughtExceptionHandler(new MyUncaughtExceptionHandler());

return t;

}

}

?

调试:

?

public class CaptureUncaughtException {

public static void main(String[] args) {

ExecutorService exec = Executors.newCachedThreadPool(

new HandlerThreadFactory());

exec.execute(new ExceptionThread());

}

}

?

class ExceptionThread implements Runnable{

public void run() {

throw new RuntimeException(); //模拟线程异常

}

}
