使用枚举enum分类存放常量-蒲公英云

使用枚举enum分类存放常量

定义一个java类，在类中定义多个枚举

/** * 常量类（枚举） * * @author GaoJinShan */
public class Constants { 
    /** * 接口状态码 * * @author GaoJinShan */
    public enum ResultCode { 
        UNKNOWN_ERROR("-1", "未知错误"),
        SUCCESS("200", "成功"),
        PARAM_ERROR("201", "参数不合法"),
        DATABASE_ERROR("202", "数据库异常"),
        EXIST("403", "已存在");
        private String code;
        private String message;
        ResultCode(String code, String message) { 
            this.code = code;
            this.message = message;
        }
        public String getCode() { 
            return code;
        }
        public String getMessage() { 
            return message;
        }
    }
    /** * 网络类型 * * @author GaoJinShan */
    public enum NetworkType { 
        WIRED(1, "有线网"), WIRELESS(2, "无线网");
        private final Integer value;
        private final String name;
        NetworkType(Integer value, String name) { 
            this.value = value;
            this.name = name;
        }
        public Integer getValue() { 
            return value;
        }
        public String getName() { 
            return name;
        }
    }
}

注：这样做解决了常量多且无序的痛点

调用

/** * @param @param object * @param @return 设定文件 * @return Result 返回类型 * @Title: success * @Description: 成功有返回 */
    public static Result success(Object object) { 
        Result result = new Result(Constants.ResultCode.SUCCESS.getCode(), Constants.ResultCode.SUCCESS.getMessage());
        result.setData(object);
        return result;
    }
