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 thiswe 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;}

The solution can be found here https://github.com/spring-projects/spring-framework/issues/22734

you can create two separate post request mappings. For example.

@PostMapping(path = "/test", consumes = "application/json")public String test(@RequestBody User user) {  return user.toString();}@PostMapping(path = "/test", consumes = "application/x-www-form-urlencoded")public String test(User user) {  return user.toString();}
