提交的时候出现HTTP Status 404 - /menuAction.do

--------------------------------------------------------------------------------

type Status report

message /menuAction.do

description The requested resource (/menuAction.do) is not available.

Answer 1

看看structs-config.xml文件里配置了该action没
<action-mappings>
<action path="/……" type="……">
<forward name="success" path="/……"></forward>
</action>
……
</action-mappings>

Answer 2

description The requested resource (/menuAction.do) is not available.

没有配置这个请求

Answer 3

<form action="/menuAction.do" method="post">
记得这里不用写 "/",另外再看一下你的配置文件里，有没有配置这个action，404错误要么是提交地址写错了，要么是配置文件里写错了，有了这个方向就容易了

Answer 4

首先检查您的Status的配置文件是否配置了您的这个action地址，其次检查您的工程路径是否被修改过了。如果两样都没有的话，请检查您的Status配置中是否配置了要使用的实体类，但是从404的错误来看~应该还是路径的问题
