Struts2:多个提交按钮 [英] Struts2: multiple submit button

问题描述

我想在我的jsp中有2个提交按钮，所以我找到了本教程:

I would like to have 2 submit button in my jsp, so I found this tutorial: http://struts.apache.org/release/2.3.x/docs/multiple-submit-buttons.html I want to develop the Nyong Nyong's solution with MyBaseAction class, extended by MySubmitAction and MyClearAction class. But I can't get it work. I'm not sure how the jsp will be, this is in the example:

<s:form method="post" action="mySubmitAction">
    <s:submit value="Submit"/>
    <s:submit value="Clear" action="myClearAction"/>
</form>

但是我想它是指前面的例子. 我不太清楚struts.xml，是否需要设置一些特定的常量值或其他内容?

But I suppose that it's referred to the previous example. I'm not sure too about the struts.xml, do I need to set some specific constant value or other stuff?

如果有人可以提供完整的jsp和struts.xml示例，那就太好了.

Would be great if somebody could provide a full jsp and struts.xml example.

推荐答案

如果您在2.3.15.2之前的版本更新中使用struts，则必须将此常量添加到struts.xml中以启用action:前缀:

If you are using struts in a version newer than 2.3.15.2, you must add this constant to struts.xml to enable the action: prefix:

<constant name="struts.mapper.action.prefix.enabled" value="true" />

因为默认情况下它已被禁用.

because it has been disabled by default.
