The requester submits a request to the Service Provider, who queues up the message and returns a correlation ID that the Requester can use later to check on the status of the request.

请求者向服务提供者发出一个请求，服务提供者将请求消息放入队列并返回一个相关的 ID 。 请求提供者可以根据此 ID 在以后的时间里检查消息的状态。

Orders are sent individually, the response from each order being stored for later aggregation into a single response message, which shows the status of all the elements in the batch request.

Orders是分别发送的，并为稍后聚合为单个响应消息存储每个订单的响应，从而显示批处理请求中所有元素的状态。

youdao

In line 5 we create an ActionMessages instance to hold a status message, and in lines 12 — 14 and 17 — 19 we save the ActionMessages into the request so they can be rendered in the view.

在第5行我们创建了一个ActionMessages实例来保存状态信息，而在第12 - 14行和17 - 19行我们将ActionMessages保存到了request中，这样它们就可以在视图中被渲染。
