在 Struts 2 中是否有不同的方式来配置动作？

Question

I have requirement to migrate legacy (Struts 1) code to Struts2.

If there are multiple methods in same action class, can we configure them in single <action> tag?

struts.xml

 <?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="default" extends="struts-default">

<action name="product" 
        class="com.ProductAction"
        method="show">
<result name="success">welcome.jsp</result>
</action>

<action name="product" 
        class="com.ProductAction"
        method="showErr">
<result name="error">error.jsp</result>
</action>

</package>
</struts>    

Here, I have single action ie product and single action class ie ProductAction . So, can I configure both the methods ( show , showErr ) in single <action> tag?

Answer 1

The action name is overridden if used in the same package. The action name maps to a specific method or execute .

You can use wildcard mapping to put a method name in the action.

<action name="*product" class="com.ProductAction" method="{1}">
