安装教程

安装： 1 下载安装包：https://pan.baidu.com/s/1jJF5mUvb2tlpMzRcoJHi0g

2 解压缩ROOT.war，修改类路径下的application.properties文件，增加如下配置：

#配置注册中心

eureka.client.serviceUrl.defaultZone = http://eureka1/,http://eureka2/

eureka.client.healthcheck.enabled = true

eureka.client.fetchRegistry = true

eureka.client.registry-fetch-interval-seconds = 5

#eureka-service-url-poll-interval-seconds = 20

eureka.instance.lease-renewal-interval-in-seconds = 10

eureka.instance.lease-expiration-duration-in-seconds = 30

#eureka.instance.hostname = localhost

eureka.instance.instance-id = \${spring.cloud.client.ipAddress}:\${spring.application.name}:\${server.port}:\${_version}

eureka.instance.metadata-map.h-x-app-version = \${_version}

eureka.instance.preferIpAddress = true

#应用基础配置

spring.output.ansi.enabled = ALWAYS

application.id = 10246

server.port = 10246

spring.application.name = distributed-id-service

#此应用可以不用配置 spring.application.key =......

spring.output.ansi.enabled = ALWAYS

spring.http.encoding.charset = UTF-8

druid.driver-class-name = com.mysql.jdbc.Driver

druid.url = jdbc:mysql://xxxx:3306/distributed_id?useOldAliasMetadataBehavior=yes&zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=UTF-8

druid.username = xxxx

druid.password = xxxx

druid.initial-size = 1

druid.max-active = 20

druid.max-wait = 60000

druid.filters = stat

druid.min-idle = 3

druid.time-between-eviction-runs-millis = 60000

druid.min-evictable-idle-time-millis = 300000

druid.validation-query = select 1

druid.test-while-idle = true

druid.test-on-borrow = false

druid.test-on-return = false

#druid.connection-properties = clientEncoding=UTF-8;serverTimezone=Asia/Shanghai

mybatis.type-aliases-package = om.homedo.**.po

mybatis.mapper-locations = classpath:mapper/*_mapper.xml

mapper.identity = mysql

#默认开启

#generate.id.enable = true

#默认开启

#generate.no.enable = true

#zookeeper ip地址，多个一英文逗号分隔

generate.no.zkAddress = zkIpxxxxx

#zookeeper port 2181

generate.no.zkPort = zkPortxxxx

x-springfox.documentation.swagger.v2.basePackage = com.homedo.microservice.distributed.id.service.remote.api.impl

x-springfox.documentation.swagger.v2.title = 分布式ID服务相关接口

x-springfox.documentation.swagger.v2.description = 提供完整的接口文档，可以模拟接口操作

#注意：加粗的属性，需要替换成自己真实的配置

3 数据库脚本

CREATE DATABASE `distributed_id` /*!40100 DEFAULT CHARACTER SET utf8mb4 */;

CREATE TABLE `leaf_alloc` (

`biz_tag` varchar(128) NOT NULL DEFAULT '',

`max_id` bigint(20) NOT NULL DEFAULT '1',

`step\` int(11) NOT NULL,

`description` varchar(256) DEFAULT NULL,

`update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

PRIMARY KEY (`biz_tag`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

4 把修改后的ROOT文件夹放入tomcat等容器中，启动tomcat即可

使用说明

• 全局唯一性
• 趋势递增：有序。
• 单调递增：下一个ID一定大于上一个ID
• 信息安全：单号无规则、不规则。

在线Demo：

1 全局ID： http://180.76.250.110:10246/distributed-id-service/generateId/test-id

2 全局单号： http://180.76.250.110:10246/distributed-id-service/generateNo/test-no

详述： 一 DISTRIBUTED-ID-SERVICE 提供生成服务

1 全局ID生成接口

   /distributed-id-service/generateId/{key}

  key对应业务标志：格式为 “数据库名_表名”，例如库名是 framework_gateway，表名是e_user，对应的key为 framework_gateway_e_user （注意：严格区分大小写，一个字母的大小写不同即代表是不同的业务标志，建议传的时候全转小写或大写）

  建表注意：

      1.1 表主键不能是自增的

      1.2 新表可以直接接入，从1开始全局递增

      1.3 老表接入，需要预设一个起始值，防止与库中已有的主键值产生冲突

      1.4 新表有默认插入数据的，也须预设一个起始值，防止与库中已有的主键值产生冲突

2 全局单号生成接口，返回单号是长度19的纯数字。调用方可以根据自身实际需求，自定义前缀标志（注意：不加前缀标志此单号也是全局唯一的）

  /distributed-id-service/generateNo/{key}

  key对应业务标志，可以是服务名称，暂仅做排错标志
