统一返回对象突然多个success属性

今天在测试的时候突然发现统一返回对象里面多个success属性:

@Data
    @Accessors(chain = true)
    public class ApiResponse<T> { 
        private int code;
        private String reason;
        private T data;
    
        public ApiResponse(T data) { 
            this.data = data;
        }
    
        public ApiResponse(String reason, int code) { 
            this.code = code;
            this.reason = reason;
        }
    
        public ApiResponse() { 
        }
    
        public boolean isSuccess() { 
            return ResultCode.SUCESS.getErrorCode() == code;
        }
    
        public static <T> ApiResponse success(T data) { 
            ApiResponse<T> responseResult = new ApiResponse<T>(data);
            responseResult.setCode(ResultCode.SUCESS.getErrorCode());
            return responseResult;
        }
    
        public static <T> ApiResponse fail(T data) { 
            ApiResponse<T> responseResult = new ApiResponse<T>();
            responseResult.setCode(ResultCode.INTERNAL_ERROR.getErrorCode());
            responseResult.setReason(data.toString());
            return responseResult;
        }
    
    
        public static void main(String[] args) { 
            ApiResponse success = ApiResponse.success(1);
            System.out.println(JSONObject.toJSONString(success));
    
            HashMap<Object, Object> objectObjectHashMap = Maps.newHashMap();
            objectObjectHashMap.put("code", 1);
            objectObjectHashMap.put("reason", 1);
            objectObjectHashMap.put("data", 1);
            System.out.println(JSONObject.toJSONString(objectObjectHashMap));
    
        }
    }

这是resoult返回的枚举.

public enum ResultCode { 
        SUCESS(0, "请求成功"),
        NO_CONTENT(204, "请求无内容"),
        USER_NOT_LOGIN(401, "用户未登录"),
        USER_LOGIN_FAIL(-2, "用户登录失败"),
        USER_ACCESS_FORBIDDEN(403, "用户授权失败"),
        NOT_FOUND(404, "资源不存在"),
        INTERNAL_ERROR(500, "服务器错误"),
        SYSTEM_ERROR(501, "系统繁忙"),
        BUSINESS_SUCESS(1, "数据正常返回"),
        UNKNOWN(-1, "系统异常"),
        BUSINESS_FAILURE(-2, "业务异常"),
        INVALID_ARGUMENT(11001, "非法参数");
    
        private static final Map<Integer, ResultCode> values = new HashMap();
        private int errorCode;
        private String error;
    
        private ResultCode(int errorCode, String error) { 
            this.errorCode = errorCode;
            this.error = error;
        }
    
        public static ResultCode valueOf(int code) { 
            ResultCode ec = (ResultCode) values.get(Integer.valueOf(code));
            return ec != null ? ec : UNKNOWN;
        }
    
        public int getErrorCode() { 
            return this.errorCode;
        }
    
        public String getError() { 
            return this.error;
        }
    
        static { 
            ResultCode[] var0 = values();
            int var1 = var0.length;
    
            for (int var2 = 0; var2 < var1; ++var2) { 
                ResultCode ec = var0[var2];
                values.put(Integer.valueOf(ec.errorCode), ec);
            }
    
        }
    }

这是执行结果:

转成json的时候多个success属性,然后查看ApiResponse里面有个isSuccess方法,去掉之后,success属性没有,  
**怀疑是方法名称叫做isSUccess方法,然后进行json序列化的的时候加上了这个属性.用的阿里的fastjson.**

在isSuccess方法打个断点:  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4MzY2MDYz_size_16_color_FFFFFF_t_70]  
序列化的时候,debug进来了.应该是fastjson序列化的时候把属性加上去了.  
但是倒数第二个栈点进不去  
阿里开发手册:  
![在这里插入图片描述][20191114114016163.png]  
fastjson和jackson在把对象序列化成json字符串的时候，是通过反射遍历出该类中的所有getter方法，得到getHollis和isSuccess，然后根据JavaBeans规则，他会认为这是两个属性hollis和success的值。直接序列化成json:\{“success”:true\}  
[为什么强烈禁止开发人员使用isSuccess作为变量名][isSuccess]
