Struts2 - Can an action name be repeated in the struts.xml using the same action class but for different methods?

问题

My idea is to perform actions using Struts2 the below way using a single Action class and multiple methods in it:

View roles action: manage/roles.action?method%3Aview=View Add role action: manage/roles.action?method%3Aadd=Add

The URLs are called through invoking submit buttons as shown below from test.jsp:

<s:form namespace="/manage/" action="roles" method="get" >
    <s:submit method="view" value="View" />
    <s:submit method="add" value="Add" />
    <s:submit method="edit" value="Edit" />
    <s:submit method="delete" value="Delete" />
</s:form>

In struts.xml, I configured:

 <package name="portal" namespace="/manage/" extends="struts-default">
    <action name="home">
        <result>/WEB-INF/jsp/manage/roles/test.jsp</result>
    </action>

    <action name="roles" class="struts2.actions.RoleAction" method="view">
        <result name="success">/WEB-INF/jsp/manage/roles/viewRoles.jsp</result>
    </action>

    <action name="roles" class="struts2.actions.RoleAction" method="add">
        <result name="input">/WEB-INF/jsp/manage/roles/addRole.jsp</result>
        <result name="success">/WEB-INF/jsp/manage/roles/viewRoles.jsp</result>
    </action>

Unfortunately, when I'm pressing View button, it's showing the result JSP of "add" method. Why?

回答1:

Because you have two actions with the same name, roles.

How would you differentiate between... /roles and /roles?

They should have different names–different URLs. Since they're the same URL the last one configured will win; you're overwriting your own definitions. How about giving them different names, like /addrole and /viewrole, or namespacing them, like /roles/add and /roles/view, etc.?
