Converting ajax GET request parameters to domain object and passed to Spring Controller like @RequestBody

Here is my jquery ajax ajax request

$.ajax({
  url: "/some_url",
  type: "GET",
  contentType : "application/json; charset=utf-8",
  async: false,
  data: {"attribute_1":"some_value_1","attribute_2":"some_value_2"};,
  cache: false,
  success: function(response) {}
});

Here is my controller method 

@RequestMapping(value = "/some_url", method = { RequestMethod.GET })
public String getDetails(HttpServletRequest request,@RequestBody CustomDTO customDTO) {
}

But request does not reach controller method and get 404 error ? If I make it post at ajax and controller level it works. I understand @RequestBody works with POST request only.

My question how can i map the input request parameters to domain object in ajax GET request under spring mvc ?

Do I have do define each parameter as getDetails(HttpServletRequest request,@RequestParam String pName1, @RequestParam String pName2,...) as defined at How to pass Json object from ajax to spring mvc controller? or is there a cleaner way to wrap them in domain object

use JSON.stringify() covert data into Json value.

code

data: ({queryData:JSON.stringify({"attribute_1":"some_value_1","attribute_2":"some_value_2"}}))

Then you send data to spring as string parameter Then convert it by using jacksonLibrary

  @RequestMapping(value = "/some_url", method = { RequestMethod.GET })

  public String getDetails(HttpServletRequest request,
                 @RequestParam String queryData) 
    {

   ObjectMapper myMapper = new ObjectMapper();
QueryData myQueryData = myMapper.readValue(queryData, CustomDTO.class);

  //now you can access data... 
     myQueryData.getattribute_1(); 
    myQueryData.getattribute_2(); 
 }
