I made some minor modification to you code and tested it with a spring project that I have and it works   The logic will only work with POST if I use GET it throws an error with invalid request  Also in your ajax call I commented out commit true   the browser debugger flagged and error that it is not defined   Just modify the url to fit your Spring project architecture        ajax                        url    addDepartment                        method   POST                        dataType   json                        data      message     abc     success   true                        contentType   application json                       mimeType   application json                       success  function data                             alert data success         data message                             commit true                                              error function data status er                             alert  error    data   status    status   er   er                                                 RequestMapping value   addDepartment   method RequestMethod POST    public AjaxResponse addDepartment  RequestBody final AjaxResponse  departmentDTO          System out println  addDepartment   gt  gt  gt  gt  gt  gt  gt    departmentDTO       AjaxResponse response new AjaxResponse        response setSuccess departmentDTO isSuccess         response setMessage departmentDTO getMessage         return response

I also had the same problem  I use  Postman  for JSON request  The code itself is not wrong  I simply set the content type to JSON  application json  and it worked  as you can see on the image below

Try this    RequestBody required   false  String str

User · Answer

In my side  it is because POSTMAN setting issue  but I don t know why  maybe I copy a query from other  I simply create a new request in POSTMAN and run it  it works

User · Answer

If it s working from Postman  try new Spring version  becouse the  org springframework boot  2 2 2 RELEASE version can throw  Required request body content is missing  exception  Try 2 2 6 RELEASE version

Sorry guys   actually because of a csrf token was needed I was getting that issue  I have implemented spring security and csrf is enable  And through ajax call I need to pass the csrf token

User · Answer

You shouldn t send a request body with an HTTP GET request  You should modify addDepartment   so that it only supports POST  and POST your JSON to that endpoint  If you want to GET information about a department  you should create a separate controller method that does that  and does not require a request body    Also  double-check your endpoint definitions since you have misspelled  reimbursement  in the   ajax call

[java] Required request body content is missing: org.springframework.web.method.HandlerMethod$HandlerMethodParameter
