Struts2 默认Action和模块包含

在我们定义Action的时候会希望有一个默认的action在写错action时或者不写action时不至于报错

这里我只写一个简单的strut.xml例子

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">



<struts>

    <!-- Add packages here -->

     <constant name="struts.devMode" value="true" />

    <constant name="struts.enable.DynamicMethodInvocation" value="true"/>

    <package name="default" namespace="/abc" extends="struts-default">      

       <default-action-ref name="index"></default-action-ref>         

       <action name="index" class="com.pengli.struts.parampack.MyActionOne"  method="Def">

               <result>

                   /index.jsp

               </result>

       </action>

    </package>

</struts>

除了这个也可以用全局的

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">



<struts>

    <!-- Add packages here -->

     <constant name="struts.devMode" value="true" />

    <constant name="struts.enable.DynamicMethodInvocation" value="true"/>

    

    <!-- Add packages here -->   

    

    <package name="defalutError" namespace="/" extends="struts-default">

        <global-results>

            <result name="error">

                /Errors.jsp

            </result>

        </global-results>

    </package>

    

    <package name="testdefalult" namespace="/abc" extends="defalutError">

                  

        

     

       <action name="index" class="com.pengli.struts.parampack.MyActionOne"  method="Def">

               <result >

                   /index.jsp

               </result>

       </action>

    </package>

    

    

</struts>

 

有时候我们也是需要模块化struts.xml在多人开发时更加灵活

我们再建一个xml文档

struts.xml代码

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">



<struts>

    <!-- Add packages here -->

     <constant name="struts.devMode" value="true" />

    <constant name="struts.enable.DynamicMethodInvocation" value="true"/>

    

    <include file="testModel.xml"></include>

</struts>

testModel.xml

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">



<struts>

    <!-- Add packages here -->

    <package name="testdefalult" namespace="/abc" extends="struts-default">      

       <default-action-ref name="index"></default-action-ref>         

       <action name="index" class="com.pengli.struts.parampack.MyActionOne"  method="Def">

               <result>

                   /index.jsp

               </result>

       </action>

    </package>

</struts>
