(-) 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.
