为具有不同参数的相同网址格式创建两个方法 [英] create two method for same url pattern with different arguments

问题描述

我遇到一种情况，其中一个网址"serachUser"可能带有两个不同的值(请求参数)userId或UserName.

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

为此，我创建了两个方法

so for this I have created two methods

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

但是我正在获取模棱两可的映射，发现异常. Spring可以处理这种情况.

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

推荐答案

您可以使用

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) {
  // ...
}
