Getting exception while passing JSON data from JQUERY to java controller

Question

I am passing JSON data from jQuery to my Java controller and I am using @RequestBody, but I am getting an exception saying:

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

The data which I am passing is:

myData = {
  "source": "CSS",
  "type": "CSS2",
  "typeValue": "value",
  "textarea_value": " desc"
}:

The AJAX call I am using to pass this data is:

$.ajax({
  url: './common/deleteData',
  type: 'POST',
  data: myData,
  success: function(data) {
    alert("Successfully Deleted Source..");
  },
  error: function(data) {}
});

My Java Controller is as below

@RequestMapping(value = "/common/deleteData", method = RequestMethod.POST, consumes = {"application/x-www-form-urlencoded; charset=UTF-8"})
public String deleteData(@RequestBody SourceDelete sourcedelete, final HttpServletRequest request, final RedirectAttributes rdtAttribs) throws ApplicationException 
{
  LOGGER.entry("Deleting the Merge Preference Details");
  System.out.println(sourcedelete.getSource());
  return null;
}

My POJO object is as below:

public class SourceDelete {
  private String source;
  private String type;
  private String typeValue;
  private String textarea_value;
  //Setters and Getters
}

Can someone please help me figure out why I am getting this error and how I should fix it.

*Writing a JSON REST service in Spring Boot is simple, as that's its default opinion when Jackson is on the classpath:* see https://www.baeldung.com/spring-boot-json — Scary Wombat, Sep 25 '19 at 07:54

@vyas in your ajax call add dataType: "json" and contentType: "application/json; charset=utf-8" both are missing see https://stackoverflow.com/questions/18980841/how-to-call-ajax-request-with-json-response-using-jquery — Richard Elite, Sep 25 '19 at 08:16

remove the @RequestBody annotation,

@RequestMapping(value = "/common/deleteData", method = RequestMethod.POST, consumes = {"application/x-www-form-urlencoded; charset=UTF-8"})
public String deleteData(SourceDelete sourcedelete, final HttpServletRequest request, final RedirectAttributes rdtAttribs) throws ApplicationException 
{
  LOGGER.entry("Deleting the Merge Preference Details");
  System.out.println(sourcedelete.getSource());
  return null;
}
