java - 从 java 任务抛出异常不起作用

Question

我试图在单独线程上运行的任务中抛出异常。然后我想捕获调用线程上的异常。请参阅下面我的试用:
当我现在运行代码时，它卡在“抛出新的 RuntimeException..”行上

Task calcTask = createCalcTask();

ExecutorService executor = Executors.newFixedThreadPool(1);
Future future = executor.submit(calcTask);
try {
    future.get();
} catch (ExecutionException ex) {
    ex.getCause().printStackTrace();
} catch (InterruptedException e1) {
    e1.printStackTrace();
}

public Task<Object> createCalcTask() {
    return new Task<Object>() {
        @Override
        protected Object call() throws Exception {              
            throw new RuntimeException("testE");
        }
    };
}

试试这个.... 抛出异常的行应该位于 try block 内

try {
   Future future = executor.submit(calcTask); //
   future.get();
} catch (ExecutionException ex) {
   ex.printStackTrace();
}
