Spring - Annotation Based Controller - RequestMapping based on query string

In Spring annotation-based controller, is it possible to map different query strings using @RequestMapping to different methods?

For example

@RequestMapping("/test.html?day=monday")
public void writeMonday() {
}


@RequestMapping("/test.html?day=tuesday")
public void writeTuesday() {
}

Yes, you can use the http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/web/bind/annotation/RequestMapping.html#params()">params</a> element:

@RequestMapping("/test.html", params = "day=monday")
public void writeMonday() {
}

@RequestMapping("/test.html", params = "day=tuesday")
public void writeTuesday() {
}

You can even map based on the presence or absence of a param:

@RequestMapping("/test.html", params = "day")
public void writeSomeDay() {
}

@RequestMapping("/test.html", params = "!day")
public void writeNoDay() {
}

or you could do something like:

@RequestMapping("/test.html")
public void writeSomeDay(@RequestParam String day) {
   // code to handle "day" comes here...
}
