spring mvc - Signature of Methods Returning ModelAndView and Request Mapping by Method Name -

-

two beginner springmvc questions:

1) there required signature types in springmvc modelandview-returning methods, or it's free-form, whatever params/order want? i've seen these examples:

public modelandview action1(httpservletrequest request); public modelandview action2(model m); public modelandview action2(httpservletrequest request, model m); public modelandview action4(); //etc.

2) possible have requestmapping method name, not whole url? have url, /test, can either /test?method=action1 or /test?method=action2 (similar struts).

@requestmapping("/test?method=action1") public modelandview action1(model m) { //... }
