调用Struts2动作并将结果消费为Stream

Question

Is this possible, within the Struts2 framework, and/or am I limited to using the URL/URLConnection classes to get the response as a stream? I've looked into the ActionComponent class but I'm not sure how to use it?

Thanks.

Answer 1

I believe what you want is to use a StreamResult in your action. Check out the following:
