@RequestMapping type-level params not taken into account consistently [SPR-5421]

[spring-projects-issues]

Ken Sipe opened SPR-5421 and commented

Given the following code:
@Controller
@RequestMapping(param="ex")
public class BookController {

@RequestMapping
public void index() {  }

@RequestMapping(param="id")
public void show() {  }

}

one would expect that in order to invoke either request mapping that an "ex" parameter woud need to be present in the request. so /book/index?ex=a or /book/show?id=1&ex=a . however testing this out, the param requires are as expected for the show method... however a simple /book/index works without a parameter on the index. As I think this through, it is the only default request mapping, however given the restriction on the type shouldn't this request fail with no matching mapping?

Affects: 3.0 M1

The primary problem was that for non-singleton controllers, the checking of type-level constraints was accidentally bypassed. It should work consistently now as of 3.0 M2.
