Let's follow the editor to learn more about "what points to pay attention to when using struts menu in Struts2".

Struts menu in Struts1.0

Menu-config.xml is the menu configuration file!

Add the following code to the struts-config.xml file of struts1.2:

The parameter is: menuConfig corresponding value is: menu configuration file path!

Struts menu in Struts2.0

In the menu-config.xml file

Note that when adding entries, be sure to modify the Item name attribute, do not repeat, otherwise it will not be displayed properly!

Struts menu in Struts3.0

Configure struts-menu in struts2

In the past, you needed to configure in struts-config.xml in struts1.x to introduce struts-menu, but now you only need to configure a listener in web.xml.

Net.sf.navigator.menu.MenuContextListener

-MenuContextListener.java partial source code:-

Public class MenuContextListener implements ServletContextListener {

Private static Log log = LogFactory.getLog (MenuContextListener.class)

Private ServletContext ctx

Private String menuConfig = "/ WEB-INF/menu-config.xml"

Public void contextInitialized (ServletContextEvent sce) {

Ctx = sce.getServletContext ()

If (log.isDebugEnabled ()) {

Log.debug ("Starting struts-menu initialization")

}

/ / check for menuConfigLocation context-param

String override =

Sce.getServletContext () .getInitParameter (menuConfigLocation)

If (override! = null) {

If (log.isDebugEnabled ()) {

Log.debug ("using menuConfigLocation:" + override)

}

This.menuConfig = override

}

MenuRepository repository = new MenuRepository ()

Repository.setLoadParam (menuConfig)

.

This is much more comfortable compared to the way plug-ins are loaded in struts1, but the menu configuration file in struts2 must be: menu-config.xml

You can name it yourself in struts1!
