Struts1.2.2新功能全新体验

(-) org.apache.struts.action.Action的改动.

在Action类中增加了addMessages、addErrors、getErrors、getMessages四个方法

便于处理ActionMessages和ActionErrors.

I. protected void addMessages(

HttpServletRequest request,

ActionMessages messages)

II. protected void addErrors(

HttpServletRequest request,

ActionErrors errors)

III. protected ActionErrors getErrors(HttpServletRequest request)

IV. protected ActionMessages getMessages(HttpServletRequest request)

下面的代码片断是关于ActionMessages的(ActionErrors的例子类似):

ActionMessages messages=getMessages(request);

//xx.xx.xx代表Resource Bundle中的Key值.

ActionMessage msg=new ActionMessage("xx.xx.xx");

messages.add(ActionMessages.GLOBAL_MESSAGE,msg);

addMessages(request,messages);

//在1.2.2中不必调用saveMessages将ActionMessages对象保存到request.

//因为,在addMessages中已经包含了此功能.

//具体可参见Struts 1.2.2的Action源代码.
