Spring异步任务@asynch

AOP+JCU的ThreadPool和Future实现了异步任务，很简单，直接看spring实现的源代码吧：

public Object invoke(final MethodInvocation invocation) throws Throwable {
		Future result = this.asyncExecutor.submit(new Callable<Object>() {
			public Object call() throws Exception {
				try {
					Object result = invocation.proceed();
					if (result instanceof Future) {
						return ((Future) result).get();
					}
				}
				catch (Throwable ex) {
					ReflectionUtils.rethrowException(ex);
				}
				return null;
			}
		});
		if (Future.class.isAssignableFrom(invocation.getMethod().getReturnType())) {
			return result;
		}
		else {
			return null;
		}
	}
