通过二进制位处理多种选择的业务类型

## 项目情况 ##

*  对接了多个钱包项目，各个钱包直接各种业务收费标准不一样
 *  比如 A钱包充值收钱少 B钱包提现收钱少，A钱包某几天提现免费
 *  需要实时更改选中的钱包渠道，此时用二进制刚好

## 上代码 ##

建表

CREATE TABLE `wallet_channel_config`  (
      `id` bigint(64) NOT NULL AUTO_INCREMENT,
      `channel_code` varchar(512) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '渠道标识',
      `channel_name` varchar(512) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT '' COMMENT '渠道名称',
      `weight` int(11) NULL DEFAULT NULL COMMENT '权重',
      `status` int(11) NULL DEFAULT NULL COMMENT '状态',
      `handler` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '解析器',
      `tags` varchar(32) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT '进制码',
      `tag` int(11) NULL DEFAULT NULL COMMENT '值',
      `create_at` datetime(0) NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
      `update_at` datetime(0) NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP(0) COMMENT '更新时间',
      PRIMARY KEY (`id`) USING BTREE,
      INDEX `idx_channel_code`(`channel_code`) USING BTREE
    ) ENGINE = InnoDB AUTO_INCREMENT = 1000 CHARACTER SET = utf8 COLLATE = utf8_bin COMMENT = '钱包渠道配置表' ROW_FORMAT = Dynamic;

表结构及数据

TranType

public enum TranType { 
    
        DEPOSIT("deposit",1,"充值"),
    
        WITHDRAW("withdraw",2,"提现"),
    
        VALID_ADD("withdraw",4,"校验地址合法性"),
        
        TEST("withdraw",8,"测试添加");
    
    
        private String code;
    
        private Integer value;
    
        private String name;
    
        TransactionType(String code, Integer value,String name){ 
            this.code = code;
            this.value = value;
            this.name = name;
        }
    
        public String getCode() { 
            return code;
        }
    
        public Integer getValue() { 
            return value;
        }
    
        public String getName() { 
            return name;
        }}

枚举里面设定了三种业务类型，数据库通过 `tags`设定了四种类型

*  查询合法性

 *  测试 选择

 *  提现

    这样通过进制选择合适的配置 效率刚刚的

## java ##

if ((ping.getStatus() & status) == 0) { 
                status += ping.getStatus();
            }
    3 & 1 =1；
    3 & 2 =2；
    3 & 4 =0；
