## Result ##

/** * Created by 李柏霖 * 2020/10/19 17:37 */
    
    package com.lbl.VO;
    
    import lombok.AllArgsConstructor;
    import lombok.NoArgsConstructor;
    
    @AllArgsConstructor
    @NoArgsConstructor
    public class Result { 
        private int code;//编码 404 200
        private String msg;//提示信息
        private Object data; //数据
    
        public static Result init(int code,String msg,Object data){ 
            Result result = new Result(code, msg, data);
            return result;
        }
    }

### 错误原因：实体类缺少get set 方法 ###

### 加入get set 方法即可 或者使用lombok增加@Data注解 ###

## Result ##

/** * Created by 李柏霖 * 2020/10/19 17:37 */
    
    package com.lbl.VO;
    
    import lombok.AllArgsConstructor;
    import lombok.Data;
    import lombok.NoArgsConstructor;
    
    @Data
    @AllArgsConstructor
    @NoArgsConstructor
    public class Result { 
        private int code;//编码 404 200
        private String msg;//提示信息
        private Object data; //数据
    
        public static Result init(int code,String msg,Object data){ 
            Result result = new Result(code, msg, data);
            return result;
        }
    }

加了@data注解之后，没可以正常访问了！！！

如图：
