Http Post request with content type application/x-www-form-urlencoded not working in Spring

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


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;
}
