如何将数据从一个Web服务发送到另一个？

Question

I have two Java web services deployed on Glassfish server, both inside the same web application. What is the easiest way to send an authorisation token (10 digit number) from one web service to another?

Thanks.

Answer 1

That depends entirely on what you mean by send .

I assume that you just mean that you want to allow web service #2 to have access to the token generated by web service #1?

There are a few options here, but a couple that jump to mind are:

• store the token in a Map backed Singleton . This will be available application wide.
• store the token in a Map under the ServletContext via the set/getAttribute() methods. You should be able to access the ServletContext via the WebServiceContext in web service #1 and #2 by doing something like: webServiceContext.getMessageContext().get(MessageContext.SERVLET_CONTEXT);

These assume that you can key into the token somehow (via a user id or something).

Additionally, this doesn't cover the duration for which the auth' token is considered valid and whether it should be valid when the app' is stopped/started/redeployed. Above also doesn't consider load balancing or anything funky like that; it's assuming that you're running a single Glassfish instance.
