Struts 配置拦截器导致 验证的某某Action-vationdation.xml文件不好使的问题

参考原文

在配置了struts的拦截器后，之前的验证文件Action-validation.xml文件就不起作用了。原来是设置拦截器的问题。

Action-validation.xml文件如下：(RegisterAction-test-validation.xml )

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

<validators>
<validator type="requiredstring">
<param name="fieldName">username</param>
<param name="fieldName">password</param>
<message>${fileName} not field should not be blank</message>
</validator>

<validator type="stringlength">
<param name="fieldName">username</param>
<param name="fieldName">password</param>
<param name="min">6</param>
<param name="max">10</param>
<message>${fieldName} should ${min} to ${max}</message>
</validator>
</validators>

初始struts.xml文件如下：

<?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.custom.il8n.resources" value="message"></constant>
<package name="struts2" extends="struts-default">
<interceptors>
<interceptor name="MyInterceptor" class="com.test.interceptor.MyInterceptor">
<param name="myParams">i am params</param>
</interceptor>
</interceptors>
<action name="PointConverter" class="com.test.action.PointAction">
<result name="success">/output.jsp</result>
<result name="input">/input.jsp</result>
</action>
<action name="register" class="com.test.action.RegisterAction"
method="test">
<result name="success">/success.jsp</result>
<result name="input">/register2.jsp</result>
<interceptor-ref name="MyInterceptor"></interceptor-ref>
</action>
</package>
</struts>

这个时候以前书写的验证文件就不起作用。原因是 interceptor 只能有一个默认的interceptor 就是defaultStack 在struts-default.xml 中

修改struts.xml文件 我这里用一个interceptor-stack 拦截器栈 跟问题本身没有关系，如下

<?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.custom.il8n.resources" value="message"></constant>
<package name="struts2" extends="struts-default">
<interceptors>
<interceptor name="MyInterceptor" class="com.test.interceptor.MyInterceptor">
<param name="myParams">i am params</param>
</interceptor>
<interceptor-stack name="myInterceptorStack">
<interceptor-ref name="MyInterceptor"></interceptor-ref>
<interceptor-ref name="defaultStack"></interceptor-ref>
</interceptor-stack>
</interceptors>
<action name="PointConverter" class="com.test.action.PointAction">
<result name="success">/output.jsp</result>
<result name="input">/input.jsp</result>
</action>
<action name="register" class="com.test.action.RegisterAction"
method="test">
<result name="success">/success.jsp</result>
<result name="input">/register2.jsp</result>
<interceptor-ref name="myInterceptorStack"></interceptor-ref>
</action>
</package>
</struts>

这样之前配置的校验就可以正常执行校验了。
