Spring - Annotation Based Controller - RequestMapping based on query string

Question

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() {
}

Answer 1

Yes, you can use the params 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() {
}
