Cannot map handler - There is already handler with @Controller and not unique requestMappings [SPR-5697]

[spring-projects-issues]

Bertalan Fodor opened SPR-5697 and commented

Using context:component-scan with @Controller annotation I get automatic mappings.
For example:

@Controller
public class FormController becomes: /form/*

If I have a request handler in FormController like

@RequestMapping("init.do")
public String init() { }

it gets mapped to /form/init.do
Alright this way.
But if I create another controller like

@Controller public class ContactController { 

    @RequestMapping("init.do")
    public String init() { }

}

it isn't mapped to /contact/init.do as I would expect, but throws the error:
Cannot map handler [formController] to URL path [init.do]: There is already handler [com.company.FormController@f8b79a] mapped.

I see the same issue with Spring 3-RC3.

This is most likely an issue with your HandlerMapping: Your controllers seem to be designed for ControllerClassNameHandlerMapping. Do NOT use such controllers with DefaultAnnotationHandlerMapping, since the latter expects a specific type-level @RequestMapping: It does not take the controller class name into account but rather treats each method-level mapping as a full path mapping if no type-level mapping has been defined.
