使用Seam / JSF获取表单请求

Question

I have a query form that I would like to submit as a GET request so the result page may be bookmarked and otherwise RESTful. It's your classical text field with a submit button. How do I induce Seam/JSF to use GET and include the query expression as a parameter rather than POST, the default?

Answer 1

All you need to do is enable the SeamFilter in web.xml. See Blog Example for an example RESTful application using Seam. The key is to use a Seam page parameter, defined in WEB-INF/pages.xml

Answer 2

you can use a PhaseListener to convert POST requests to GET requests or just to interpret GET requests so that they can be bookmarkable.

This page should explain in more detail:

Answer 3

如果您使用s:button或s:link ，您的表单将使用GET方法。
