Hi Guys,
Thanks! I have thought about that. But then I decided to read the source
code.
I did some study and it seems much simpler than I thought:
The function parseActionName in class DefaultActionMapper now is look
like:
protected ActionMapping parseActionName(ActionMapping mapping) {
if (mapping.getName() == null) {
return mapping;
}
if (allowDynamicMethodCalls) {
// handle "name!method" convention.
String name = mapping.getName();
int exclamation = name.lastIndexOf("!");
if (exclamation != -1) {
mapping.setName(name.substring(0, exclamation));
mapping.setMethod(name.substring(exclamation + 1));
}
}
/**************modify start ********************/
String name = mapping.getName();
int question = name.lastIndexOf("?");
if(question !=-1){
mapping.setName(name.substring(0,question));
Map params = new HashMap();
int equal = name.lastIndexOf("=");
String key = name.substring(question+1, equal);
String value = name.substring(equal+1);
params.put(key, value);
mapping.setParams(params);
}
/**************modify end********************/
return mapping;
}
Then I run mvn to compile it and now it works great!!!
It can support <s:submit action = "actionname?param=value" />
(Not ! and ? at the same time but It will be quite easy to do that~~)
Cheers and thanks all of your help!
