public interface ObjectSerializer

Interface representing a custom serializer for fastjson. You should write a custom serializer, if you are not happy with the default serialization done by fastjson. You will also need to register this serializer through SerializeConfig.put(Type, ObjectSerializer).

 public static class Result {
     public ResultCode code;
 }
 
 public static enum ResultCode {
     LOGIN_FAILURE(8), INVALID_ARGUMENT(0), SIGN_ERROR(17);
     public final int value;
     ResultCode(int value){
         this.value = value;
     }
 }
 
 public static class ResultCodeSerilaizer implements ObjectSerializer {
     public void write(JSONSerializer serializer, 
                       Object object, 
                       Object fieldName, 
                       Type fieldType,
                       int features) throws IOException {
         serializer.write(((ResultCode) object).value);
     }
 }
 
 SerializeConfig.getGlobalInstance().put(ResultCode.class, new ResultCodeSerilaizer());
 
 Result result = new Result();
 result.code = ResultCode.SIGN_ERROR;
 String json = JSON.toJSONString(result, config); // {"code":17}
 Assert.assertEquals("{\"code\":17}", json);
