spring - create two method for same url pattern with different arguments

Question

I have scenario where one url "serachUser" may come with two different value (request parameter) userId or UserName.

so for this I have created two methods

public String searchUserById(@RequestParam long userID, Model model) 
public ModelAndView searchUserByName(@RequestParam String userName)

But i am getting Ambiguous mapping found exception. Spring has any way to handle this situation.

You can use the params parameter to filter by HTTP parameters. In your case it would be something like:

@RequestMapping(value = "/searchUser", params = "userID")
public String searchUserById(@RequestParam long userID, Model model) {
  // ...
}

@RequestMapping(value = "/searchUser", params = "userName")
public ModelAndView searchUserByName(@RequestParam String userName) {
  // ...
}
