+uid-generator-spring-boot
+==========================
+
+UidGenerator是Java实现的, 基于[Snowflake](https://github.com/twitter/snowflake)算法的唯一ID生成器。
+
+基与 [Snowflake](https://github.com/twitter/snowflake)，[百度UidGenerator](https://github.com/baidu/uid-generator)，[uid-generator-spring-boot-starter](https://github.com/wujun234/uid-generator-spring-boot-starter)
+
+
+* 更改了打包结构，抽出了Worker node id的生成接口， 使其可以自定义实现分配 Worker node id的方法， 本项目中实现了两种数据库存储的方法：
+* 支持 Spring boot Autoconfigure 
+* 支持 jdbc 和 r2dbc 两种数据库连接方式
+
+* mybatis jdbc 实现 [uid-worker-id-jdbc-spring-boot-starter](https://github.com/cooperlyt/uid-generator-spring-boot/tree/master/uid-worker-id-jdbc-spring-boot-starter)
+* mybatis r2dbc 实现 [uid-worker-id-r2dbc-spring-boot-start](https://github.com/cooperlyt/uid-generator-spring-boot/tree/master/uid-worker-id-r2dbc-spring-boot-starter)
+
+你以可以根据[接口包](https://github.com/cooperlyt/uid-generator-spring-boot/tree/master/uid-generator-api)自己实现Worker node分配的实现
+
+## 原理和性能
+
+请参见[Snowflake](https://github.com/twitter/snowflake)和[百度UidGenerator](https://github.com/baidu/uid-generator)
+
+## 使用
+
+### Maven 
+
+### spring boot autoconfig 方式
+```xml
+<dependency>
+    <groupId>uid-generator-spring-boot-starter</groupId>
+    <artifactId>uid</artifactId>
+    <version>1.0.3.RELEASE</version>
+</dependency>
+
+<!-- 选择一种 worker node 分配方式 -->
+
+<!-- jdbc -->
+
+<dependency>
+    <groupId>cooperlyt.github.io</groupId>
+    <artifactId>uid-worker-id-jdbc-spring-boot-starter</artifactId>
+    <version>1.0.1.BATE</version>
+</dependency>
+
+        <!-- 选择你的数据库jdbc驱动 -->
+<dependency>
+    <groupId>org.mariadb.jdbc</groupId>
+    <artifactId>mariadb-java-client</artifactId>
+</dependency>
+
+<!-- r2dbc -->
+
+<dependency>
+    <groupId>io.github.cooperlyt</groupId>
+    <artifactId>uid-worker-id-r2dbc-spring-boot-starter</artifactId>
+    <version>1.0.1.BATE</version>
+</dependency>
+
+        <!-- 选择你的数据库据r2dbc驱动 -->
+<dependency>
+    <groupId>org.mariadb</groupId>
+    <artifactId>r2dbc-mariadb</artifactId>
+    <version>1.1.3</version>
+</dependency>
+
+```
+### spring方式 请参见 [百度UidGenerator](https://github.com/baidu/uid-generator)
+
+### 数据库（可选）
+如使用数据库实现的Worker node id分配器,需要先建立表 WORKER_NODE, 脚本：
+```sql
+DROP TABLE IF EXISTS WORKER_NODE;
+CREATE TABLE WORKER_NODE
+(
+ID BIGINT NOT NULL AUTO_INCREMENT COMMENT 'auto increment id',
+HOST_NAME VARCHAR(64) NOT NULL COMMENT 'host name',
+PORT VARCHAR(64) NOT NULL COMMENT 'port',
+TYPE INT NOT NULL COMMENT 'node type: CONTAINER(1), ACTUAL(2), FAKE(3)',
+LAUNCH_DATE DATE NOT NULL COMMENT 'launch date',
+MODIFIED TIMESTAMP NOT NULL COMMENT 'modified time',
+CREATED TIMESTAMP NOT NULL COMMENT 'created time',
+PRIMARY KEY(ID)
+) COMMENT='DB WorkerID Assigner for UID Generator',ENGINE = INNODB;
+```
+
+### spring boot 配置
+
+#### ID 生成 配置
+```yml
+uid:
+  timeBits: 30             # 时间位, 默认:30
+  workerBits: 16           # 机器位, 默认:16
+  seqBits: 7               # 序列号, 默认:7
+  epochStr: "2019-02-20"   # 初始时间, 默认:"2019-02-20"
+  enableBackward: true    # 是否容忍时钟回拨, 默认:true
+  maxBackwardSeconds: 1    # 时钟回拨最长容忍时间（秒）, 默认:1
+  CachedUidGenerator:     # CachedUidGenerator相关参数
+    boostPower: 3          # RingBuffer size扩容参数, 可提高UID生成的吞吐量, 默认:3
+    paddingFactor: 50      # 指定何时向RingBuffer中填充UID, 取值为百分比(0, 100), 默认为50
+    #scheduleInterval: 60    # 默认:不配置此项, 即不使用Schedule线程. 如需使用, 请指定Schedule线程时间间隔, 单位:秒
+```
+
+#### jdbc 配置
+
+```yml
+mybatis:
+  configuration:
+    default-fetch-size: 100
+    default-statement-timeout: 30
+    map-underscore-to-camel-case: true
+spring:
+  datasource:
+    driver-class-name: org.mariadb.jdbc.Driver
+    url: jdbc:mariadb://127.0.0.1:3306/database?
+    username: root
+    password: ****
+```
+
+#### r2dbc 配置
+
+```yml
+
+r2dbc:
+  mybatis:
+    mapper-locations: classpath:mapper/*.xml
+    map-underscore-to-camel-case: true
+spring:
+  r2dbc:
+    mybatis:
+      r2dbc-url: r2dbc:mysql://127.0.0.1:3306/database
+      username: root
+      password: ****
+      pool:
+        max-idle-time: PT3M
+        validation-query: SELECT 1 FROM DUAL
+        initial-size: 1
+        max-size: 3
+        acquire-retry: 3
+        validation-depth: REMOTE
+        max-create-connection-time: PT30S
+
+```
+
+#### 自定义 拒绝策略 
+
+```java
+  @Bean
+  RejectedPutBufferHandler customPutHandler() {
+      return (r, i) -> {
+      do your
+      };
+  }
+
+  @Bean
+  RejectedTakeBufferHandler customTakeHandler() {
+      return (r, i) -> {
+      do your
+      };
+  }
+  
+```
