Question

Struts版本是2.3.16

在struts.xml中，我添加了此

<action name="ajaxuser" class="com.pp.ajax.UserAccount">
    <result name="success">/out.jsp</result>
</action>

xml和UserAccount类是正确的，因为对此url的某些请求是正常的，但某些请求是404。

这是成功的请求

我看不出这两个请求之间有什么不同，所以我不明白为什么会出现这个问题

我还在UserAccount的开头添加了一个断点，但程序无法到达此断点，并且服务器显示此错误

WARNING: Could not find action or result: /pp/ajaxuser
No result defined for action com.pp.ajax.UserAccount and result input

我不知道如何追踪这个问题，我现在该怎么办？

Answer 1

您正在执行POST请求，验证拦截器可能会返回INPUT结果。通常，您可以通过向操作配置添加INPUT结果来解决此问题。

<action name="ajaxuser" class="com.pp.ajax.UserAccount">
    <result name="success">/out.jsp</result>
    <result name="input">/out.jsp</result>
</action>

您还可以通过从操作配置中删除validation interceptor或通过覆盖拦截器配置参数excludeMethods添加方法来从验证中排除此操作，然后您不需要此结果。

为什么struts.xml是正确的，但页面是404？
