struts2配置錯誤 There is no Action mapped for namespace [/] and action name [] associated with context

標籤：struts   there is no action m   

今天在使用struts2的時候遇到這個問題。

Struts has detected an unhandled exception:

Messages:

There is no Action mapped for namespace [/] and action name [] associated with context path [/ssm1].

這個時候的struts.xml檔案如下：

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD StrutsConfiguration 2.3//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><constant name="struts.enable.DynamicMethodInvocation" value="false"/><constant name="struts.devMode" value="true"/><constant name="struts.objectFactory" value="spring" />    <package name="default" namespace="/" extends="struts-default">        <!-- 注意：這裡的class -->        <action name="student_*" class="studentAction" method="{1}">        <result name="add_success">/add_success.jsp</result>        </action>    </package></struts>

解決方案：

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><constant name="struts.enable.DynamicMethodInvocation" value="false"/><constant name="struts.devMode" value="true"/><constant name="struts.objectFactory" value="spring" />    <package name="default" namespace="/" extends="<span style="background-color: rgb(255, 255, 0);">struts-default</span>">        <!-- 注意：這裡的class -->        <action name="student_*" class="studentAction" method="{1}">        <result name="add_success">/add_success.jsp</result>        </action>    </package></struts>

所以，多注意一下struts.xml 中的配置項，關鍵的細節點，一定要處理好。
