基于号段模式百度UID实现的分布式ID生成器kylinid

　　1、简介1.1、开源项目kylin-id: 麒麟分布式id生成器，支持号段模式、雪花算法并未发布jar到中央仓库，需要自己本地构建 1.2、介绍参考滴滴 tinyid: tinyid 是滴滴开发的 id 生成器 分布式id生成系统，简单易用、高性能、高可用的id生成系统
　　整合百度UidGenerator: UidGenerator 是 Java 实现的，基于 Snowflake 算法的唯一 ID 生成器
　　麒麟发号器支持号段模式、百度uid uid的workerId生成方式： a. 支持根据bizType生成，每次重启服务自增 b. 支持使用百度提供的方式生成workerId 2、使用说明2.1、引入依赖     com.wjk.kylin      kylin-id-spring-boot-starter      1.0.0   2.2、application.ymlkylin:   id:     server: localhost:9988     read-timeout: 60     write-timeout: 60     connect-timeout: 60     kid:       enable: true       token: 110       load-id-threshold: 0.7     uid:       enable: true       biz-type: kylin_id_example       epoch-str: 2022-09-10       time-bits: 31       worker-bits: 22       seq-bits: 10       cached-uid-generator:         boost-power: 3         padding-factor: 50  2.3、表结构2.3.1、号段模式表结构CREATE TABLE `kylin_id_info`  (    `id` bigint(0) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT ＂自增主键＂,    `biz_type` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ＂＂ COMMENT ＂业务类型，唯一＂,    `max_id` bigint(0) UNSIGNED NOT NULL DEFAULT 0 COMMENT ＂当前最大id＂,    `step` int(0) UNSIGNED NOT NULL DEFAULT 0 COMMENT ＂步长，值越大，服务端缓存就会越多＂,    `delta` int(0) UNSIGNED NOT NULL DEFAULT 1 COMMENT ＂每次id增量，增长量＂,    `version` bigint(0) UNSIGNED NOT NULL DEFAULT 1 COMMENT ＂版本号＂,    `create_time` datetime(0) NOT NULL DEFAULT ＂2022-01-01 00:00:00＂ COMMENT ＂创建时间＂,    PRIMARY KEY (`id`) USING BTREE,    UNIQUE INDEX `uniq_biz_type`(`biz_type`) USING BTREE  ) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci COMMENT = ＂id信息表＂ ROW_FORMAT = Dynamic;   CREATE TABLE `kylin_id_token`  (    `id` bigint(0) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT ＂自增id＂,    `token` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ＂＂ COMMENT ＂token，用于安全校验用，建议用不同的token来验证区分＂,    `biz_type` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ＂＂ COMMENT ＂此token可访问的业务类型标识＂,    `remark` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ＂＂ COMMENT ＂备注＂,    `create_time` datetime(0) NOT NULL DEFAULT ＂2022-01-01 00:00:00＂ COMMENT ＂创建时间＂,    PRIMARY KEY (`id`) USING BTREE,    UNIQUE INDEX `uniq_token_biz_type`(`token`, `biz_type`) USING BTREE  ) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci COMMENT = ＂token信息表＂ ROW_FORMAT = Dynamic; 2.3.2、uid表结构
　　uid表结构根据选择模式创建表就可以   CREATE TABLE `worker_node` (     `id` bigint NOT NULL AUTO_INCREMENT COMMENT ＂auto increment id＂,     `host_name` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT ＂host name＂,     `port` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT ＂port＂,     `type` int NOT NULL COMMENT ＂node type: ACTUAL or CONTAINER＂,     `launch_date` date NOT NULL COMMENT ＂launch date＂,     `modified` datetime NOT NULL COMMENT ＂modified time＂,     `created` datetime NOT NULL COMMENT ＂created time＂,     PRIMARY KEY (`id`) USING BTREE   ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci COMMENT=＂DB WorkerID Assigner for UID Generator＂;    CREATE TABLE `kylin_uid_info`  (     `id` bigint(0) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT ＂自增主键＂,     `biz_type` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ＂＂ COMMENT ＂业务类型，唯一＂,     `worker_id` bigint(0) UNSIGNED NOT NULL DEFAULT 0 COMMENT ＂工作id＂,     `version` bigint(0) UNSIGNED NOT NULL DEFAULT 1 COMMENT ＂版本号＂,     `create_time` datetime(0) NOT NULL DEFAULT ＂2022-01-01 00:00:00＂ COMMENT ＂创建时间＂,     PRIMARY KEY (`id`) USING BTREE,     UNIQUE INDEX `uniq_biz_type`(`biz_type`) USING BTREE   ) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci COMMENT = ＂id信息表＂ ROW_FORMAT = Dynamic; 2.4、使用2.4.1、启动kylin-id-server2.4.2、号段模式@GetMapping(＂/nextId＂) public Long getId(@RequestParam(＂bizType＂) String bizType) {     return IdUtil.nextId(bizType); }  @GetMapping(＂/nextIdBatchSize＂) public Long getIdBatchSize(@RequestParam(＂bizType＂) String bizType, @RequestParam(＂batchSize＂) Integer batchSize) {     List idList = IdUtil.nextId(bizType, batchSize);     for (Long id : idList) {         log.info(＂{}＂, id);     }     return 0L; } 2.4.3、UID模式@Autowired @Qualifier(＂cachedUidGenerator＂) private UidGenerator uidGenerator;  @GetMapping(＂/uid＂) public Long getUId(@RequestParam(＂batchSize＂) Integer batchSize) {     for (int i = 0; i < batchSize; i++) {         log.info(＂{}＂, uidGenerator.getUID());     }     return 0L; }
