java - 将 JSON 数据从 JQUERY 传递到 java Controller 时出现异常

Question

我正在将 JSON 数据从 jQuery 传递到我的 Java Controller ，并且我正在使用 @RequestBody，但我收到一个异常:

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

我传递的数据是:

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

我用来传递此数据的 AJAX 调用是:

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

我的Java Controller 如下

@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;
}

我的 POJO 对象如下:

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

有人可以帮我弄清楚为什么会出现此错误以及应该如何修复它。

删除@RequestBody注释，

@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;
}
