即使我发送邮件请求，也不支持Spring返回

Question

我用过

@RequestMapping(value = "/something", method = RequestMethod.POST)
public @ResponseBody String getCPBankAccounts(@RequestBody SomeRequest someRequest)


 var ajaxData={"id" : $("#id").val(),
"name" : $("#name").val(),
"age" : $("#age").val()
};
$.ajax({
        type : "POST",
        contentType : 'application/json; charset=utf-8',
        dataType : 'json',
         url: localhost:8080/something,
            xhrFields: {
                withCredentials: true
            },
        data : JSON.stringify(ajaxData),
          success: function(response) {
          },
          error: function(xhr) {
          }
        });
