                  问题描述

                  我正在 Struts2 中做一个项目,我需要在 URL 中设置一个参数,例如下面链接中的用户参数.

                  I am doing a project in Struts2 where I need of setting a parameter in URL like user parameter in below link.

                  我希望在单击表单提交按钮时传递此参数,而不是单独传递任何链接.我知道如何使用 <s:url> 做到这一点,但这样我需要创建一个链接而不是表单提交.

                  I want this parameter to be passed when I click a form submit button and not any links separately. I know how to do this with <s:url> but that way I need to create a link instead of form submit.

                  有人可以帮我提供一个代码示例如何做到这一点吗?我知道有一种方法可以使用 HTML 或 Struts1 来实现,但是如何使用 Struts2 来实现呢?如果在 struts.xml 中有办法做到这一点,请举例说明.

                  Can someone please help me with a code sample how to do this? I know there's a way to do it with HTML or Struts1 but how to do it with Struts2? If there is a way to do this in struts.xml, please explain with an example.

                  <form action="/example/xyz.action?user=george" method="POST">
                  

                  推荐答案

                  试试这个:

                  <s:form action="xyz.action" method="GET">
                      <s:hidden name="user" value="george"/>
                      // other fields
                  </s:form>
                  

                  method="GET" 将在 url 上显示您的参数,<s:hidden name="user" value="george"/> 将采用你的参数.

                  method="GET" will show your parameter on the url, <s:hidden name="user" value="george"/> will take your parameter.

                  这里也是一个例子例子
