如何在Spring Rest Api中的post方法中限制查询参数？

Question

How to restrict the query params in post method in Spring Rest Api?

URL: http://localhost:9003/test-api/getDetails

RequestBody:

{
  "name": "TestUser",
  "age": 25,
  "Email": "abc@test.com"

}

In the above URL, if there is get query params as below , we should throw error/ restrict http://localhost:9003/test-api/getDetails?dateOfBirth=26081992

My Code:

@RequestMapping(value = "/getDetails", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")
public @ResponseBody ResponseEntity<String> TestMethod(
            @Valid @RequestBody CustomerDetails customerDetails, BindingResult result,
             HttpServletRequest request) {
             //..some Actions
             }

You could bind all query parameters to a Map<String, String> or MultiValueMap<String, String> using @RequestParam . From the documentation :

If the method parameter is Map<String, String> or MultiValueMap<String, String> and a parameter name is not specified, then the map parameter is populated with all request parameter names and values.

Something like:

@RequestMapping(value = "/foo", method = RequestMethod.POST)
public ResponseEntity<String> foo(@RequestParam Map<String, String> requestParams,
                                  @RequestBody Foo foo) {
    ...     
}

Then refuse the request with a 400 status code if the map contains invalid values.
