   单目或3目的就有问题，如下
   `
   @Data
   @NoArgsConstructor
   @AllArgsConstructor
   public class ResponseEntity<T> extends LinkedHashMap<String,Object> implements Serializable {
     private long id;
     private int errCode;
     private String message;
     private T result;
     public static <V> ResponseEntity<V> fromResult(long id, V val){
       ResponseEntity<V> ret = new ResponseEntity<>();
       ret.result = val;
       ret.id=id;
       return ret;
     }
     public static ResponseEntity fromErr(long id, int errCode, String message){
       ResponseEntity ret=new ResponseEntity(id,errCode,message,null);
       return ret;
     }
     @JsonIgnore
     public Map toMap(){
         Map map= JsonUtils.fromJson(JsonUtils.toJsonString(this), HashMap.class);
         return map;
     }
   }
   `
