I'm afraid it is not the expected answer, but as it is not specified in the documentation it should be regarded as undefined.

You could just try (eventually with putting "/test/logging" method first if source file), but even if it worked, you could not be sure that it will still work with another version of Spring Framework.

My advice is: if you can, avoid such ambiguous URLs, if you cannot, just have a single catchall @RequestMapping and forward from it by hand:

@RequestMapping(value = "/test/{param1}", method = RequestMethod.GET)
public String method0(@PathVariable(value = "param1") String param1, ...
    ) { // union of all parameters for both method1 and method2
    String ret;
    if ("login".equals(param1)) {
        ret = method2(/* pass parameters for method 2 */ ...);
    }
    else {
        ret = method1(/* params for method1 */ param1, ...);
    }
    return ret;
}

public String method1(String param1, ..

public String method2(//..

That way, you have full control on what method processes what url. Not necessarily the nicest way, but it is at least robust ...
