java代码运行时间超时exception方法

final ExecutorService service = Executors.newSingleThreadExecutor();

Callable<String> theCode = new Callable<String>() {

public String call() {}

};

try {

final Future<?> future = service.submit (theCode);

sReturn = (String) future.get(4, TimeUnit.SECONDS);

}

catch (InterruptedException | ExecutionException | TimeoutException e) {

logger.warning("fail." + e.getMessage() + e.toString());

}

finally {

service.shutdown();

}

callable或runnable，使代码运行在另一个线程，主线程中计时控制而已，抛出timeout后theCode还可以继续运行直至结束，因为是两个不同的线程。
