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>
