解决方法：

struts.xml中的

<interceptors>
<interceptor name="checkLogin" class="com.chen.interceptor.LoginInterceptor" />
</interceptors>

class属性的值写成了com.chen.LoginInterceptor，也就是类所在的包名写错了。

第二个问题：点击提交按钮，页面不发生跳转。

2013-7-11 11:54:50 com.opensymphony.xwork2.util.logging.commons.CommonsLogger warn
警告: No configuration found for the specified action: '/' in namespace: ''. Form action defaulting to 'action' attribute's literal value.

原来的struts.xml配置：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="testInterceptor" extends="struts-default">
<interceptors>
<interceptor name="checkLogin" class="com.chen.interceptor.LoginInterceptor" />
</interceptors>
<default-interceptor-ref name="checkLogin" />
<action name="checkLogin" class="com.chen.action.DefaultAction">
<result name="success">/success.jsp</result>
<result name="login">/login.jsp</result>
<!--<interceptor-ref name="defaultStack" />
<interceptor-ref name="checkLogin" />
--></action>
</package>
</struts>

改成

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="testInterceptor" extends="struts-default">
<interceptors>
<interceptor name="check" class="com.chen.interceptor.LoginInterceptor" />
<interceptor-stack name="checkLogin">
<interceptor-ref name="check" />
<interceptor-ref name="defaultStack" />
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="checkLogin" />
<action name="checkLogin" class="com.chen.action.DefaultAction">
<result name="success">/success.jsp</result>
<result name="login">/login.jsp</result>
<!--<interceptor-ref name="defaultStack" />
<interceptor-ref name="checkLogin" />
--></action>
</package>
</struts>

后还是出现这个问题。

解决方法：把login.jsp中的action和namespace改成和Struts.xml里的action和namespace的属性值样就不会报错了

但是又有一个问题是，我点击按钮跳转不到成功页面上去，控制台那儿也不报错。

第三个问题：只是修改了一下struts.xml里的配置

改之前的：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="testInterceptor" extends="struts-default" namespace="/">
<interceptors>
<interceptor name="check" class="com.chen.interceptor.MyInterceptor" />
<interceptor-stack name="checkLogin">
<interceptor-ref name="check" />
<interceptor-ref name="defaultStack" />
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="checkLogin" />
<action name="public" class="com.chen.action.PublicAction">
<result name="success">/success.jsp</result>
<result name="login">/index.jsp</result>
</action>
</package>
</struts>

改之后的：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>

<interceptor name="check" class="com.chen.interceptor.MyInterceptor" />
<!--<interceptor-stack name="checkLogin">

<interceptor-ref name="defaultStack" />
</interceptor-stack>
--></interceptors>
<!--<default-interceptor-ref name="checkLogin" />
--><action name="public" class="com.chen.action.PublicAction">
<result name="success">/success.jsp</result>
<result name="login">/index.jsp</result>
<interceptor-ref name="defaultStack" />
<interceptor-ref name="replace" />
</action>
</package>
</struts>

解决方法：在struts的配置文件的package标签加了namespace="/" 这个属性

This is very likely to create a memory leak.

解决方法：

struts.xml配置文件里的问题，<package name="testInterceptor" extends="struts-default" namespace="/">里的name属性的值应该和

<action name="public" class="com.chen.action.PublicAction">
<result name="success">/success.jsp</result>
<result name="login">/index.jsp</result>
<interceptor-ref name="defaultStack" />
<interceptor-ref name="replace" />
</action>

中<interceptor-ref name="replace" />的name属性值相同。

struts.xml中的package标签里少了extends的值也是出现这个问题。
