create two method for same url pattern with different arguments

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. Can Spring handle this situation?

最佳答案

您可以使用 params参数按 HTTP 参数进行过滤:

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


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

Any way incase of request param null is allowed if you don't pass any value it will be null then you can write your coad like:

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