Http Post request with content type application/x-

问题:

Am new to spring currently am trying to do HTTP POST request application/x-www-form-url encoded but when i keep this in my headers then spring not recognizing it and saying 415 Unsupported Media Type for x-www-form-urlencoded

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/x-www-form-urlencoded' not supported

Can any one know how to solve it? please comment me.

An example of my controller is:

@RequestMapping(value = "/patientdetails", method = RequestMethod.POST, headers="Accept=application/x-www-form-urlencoded")
public @ResponseBody List<PatientProfileDto> getPatientDetails(
        @RequestBody PatientProfileDto name) {


    List<PatientProfileDto> list = new ArrayList<PatientProfileDto>();
    list = service.getPatient(name);
    return list;
}

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

Then try the following:

@RequestMapping(value = "/patientdetails", method = RequestMethod.POST,consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public @ResponseBody List<PatientProfileDto> getPatientDetails(
        PatientProfileDto name) {


    List<PatientProfileDto> list = new ArrayList<PatientProfileDto>();
    list = service.getPatient(name);
    return list;
}

Note that removed the annotation @RequestBody

回答2:

you should replace @RequestBody with @RequestParam, and do not accept parameters with a java entity.

Then you controller is probably like this:

@RequestMapping(value = "/patientdetails", method = RequestMethod.POST, 
consumes = {MediaType.APPLICATION_FORM_URLENCODED_VALUE})
public @ResponseBody List<PatientProfileDto> getPatientDetails(
    @RequestParam Map<String, String> name) {
   List<PatientProfileDto> list = new ArrayList<PatientProfileDto>();
   ...
   PatientProfileDto patientProfileDto = mapToPatientProfileDto(mame);
   ...
   list = service.getPatient(patientProfileDto);
   return list;
}

You have to tell Spring what input content-type is supported by your service. You can do this with the "consumes" Annotation Element that corresponds to your request's "Content-Type" header.

@RequestMapping(value = "/", method = RequestMethod.POST, consumes = {"application/x-www-form-urlencoded"})

It would be helpful if you posted your code.

The easiest thing to do is to set the content type of your ajax request to "application/json; charset=utf-8" and then let your api method consume json. Like this

var basicInfo = JSON.stringify(
                    {
                        firstName : playerProfile.firstName(),
                        lastName : playerProfile.lastName(),
                        gender : playerProfile.gender(),
                        address : playerProfile.address(),
                        country : playerProfile.country(),
                        bio : playerProfile.bio()
                    });

 $.ajax({
                    url: "http://localhost:8080/social/profile/update",
                    type: 'POST',
                    dataType: 'json',
                    contentType: "application/json; charset=utf-8",
                    data: basicInfo,
                    success: function(data) {



                    }
                });


@RequestMapping(value = "/profile/update", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ResponseModel> UpdateUserProfile(@RequestBody User usersNewDetails, HttpServletRequest request, HttpServletResponse response){

I am guessing the problem is that spring boot has issues submitting form data which is not json via ajax request. Note: the default content type for ajax is " application/x-www-form-urlencoded"
