重定向到 Struts 2 中的默认操作 [英] Redirect to default action in Struts 2

问题描述

我有一个在根命名空间中定义的名称为空字符串的操作，如果找到某个结果，我想从另一个操作重定向到该操作，但它似乎不起作用.

I have an action with an empty string for name defined in the root namespace, and I want to redirect to that action from another action if a certain result is found, but it doesn't seem to work.

这是默认操作

<action name="" class="com.example.actions.HomeAction">
    <result name="success" type="freemarker">freemarker/home.ftl</result>
</action>

我在包的全局结果中定义重定向:

And I'm defining the redirect in the global-results for the package:

<global-results>
    <result name="sendToRouting" type="redirectAction">
        <param name="actionName"></param>
        <param name="namespace">/</param>
    </result>
</global-results>

我试过去掉 actionName 参数，但这不起作用.如果我为 HomeAction 输入一个名称并在它的全局结果中按名称引用它，那么我假设问题是缺少重定向的操作名称.

I've tried taking out the actionName parameter, but that doesn't work. If I put a name in for the HomeAction and reference it by name in the global-results it works, so I'm assuming the problem is lack of action name for the redirect.

有什么想法吗?

推荐答案

我认为你想做的是使用 :

I think that what you want to do is use <default-action-ref />:

<package name="home" namespace="/" extends="struts-default">
    <default-action-ref name="home" />

    <action name="home" class="com.example.actions.HomeAction">
        <result name="success" type="freemarker">freemarker/home.ftl</result>
    </action>

</package>

抱歉...误读了问题:

Sorry...misread the question:

尝试将 type="redirectAction" 更改为 type="redirect"，我相当确定 redirectAction 现在是重定向.

Try changing type="redirectAction" to type="redirect", I'm fairly sure that redirectAction is now redirect.
