问题描述

我有一个包含三个按钮的表单 print / export / save .

I have a form contains three buttons print/export/save.

<s:form action="/userAction">
    <s:submit type="image" value="%{'print'}" src="/print.png" />
    <s:submit type="image" value="%{'export'}" src="/export.png" />
    <s:submit type="image" value="%{'save'}" src="/save.png" />
</s:form>

如何在 struts.xml 中映射它?

推荐答案

在 struts.xml 中，操作是通过

In the struts.xml the action is mapped via the action tag

<action name="userAction" class="...

提交按钮应包含 method 属性，以调用相应的操作方法

the submit buttons should include method attribute to call corresponding methods of the action

<s:submit type="image" value="%{'print'}" src="/print.png" method="print" />
<s:submit type="image" value="%{'export'}" src="/export.png" method="export" />
<s:submit type="image" value="%{'save'}" src="/save.png" method="save" />

注意:要映射 method 属性，您应该具有

Note: To map a method attribute you should have DMI turned on.
