1.从github拉取项目

百度ID生成器地址

2.将项目maven install到本地仓库

目的是为了后续能引入maven依赖

3.创建新maven工程

3.1 引入依赖

  <dependency>
      <groupId>com.baidu.fsg</groupId>
      <artifactId>uid-generator</artifactId>
      <version>1.0.0-SNAPSHOT</version>
  </dependency>

3.1 创建配置类

类名为IdConfig

@Configuration
@MapperScan("com.baidu.fsg.uid.worker.dao")
public class IdConfig {

    @Bean
    public DisposableWorkerIdAssigner disposableWorkerIdAssigner() {
        return new DisposableWorkerIdAssigner();
    }

    @Bean(value = "defaultUidGenerator")
    public DefaultUidGenerator initDefaultUid(DisposableWorkerIdAssigner disposableWorkerIdAssigner){
        DefaultUidGenerator defaultUidGenerator = new DefaultUidGenerator();
        defaultUidGenerator.setWorkerIdAssigner(disposableWorkerIdAssigner);
        defaultUidGenerator.setTimeBits(29);
        defaultUidGenerator.setWorkerBits(21);
        defaultUidGenerator.setSeqBits(13);
        defaultUidGenerator.setEpochStr(LocalDate.now().format( DateTimeFormatter.ofPattern("yyyy-MM-dd")));
        return defaultUidGenerator;
    }

    @Bean(value ="cachedUidGenerator")
    public CachedUidGenerator initCachedUidGenerator(DisposableWorkerIdAssigner disposableWorkerIdAssigner){
        CachedUidGenerator cachedUidGenerator = new CachedUidGenerator();
        cachedUidGenerator.setWorkerIdAssigner(disposableWorkerIdAssigner);
        return cachedUidGenerator;
    }
}

3.2 创建spring.factories

内容为

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.sf.config.IdConfig

最终结构如下

3.3 maven install到本地仓库

4.自己项目中引入starter

4.1 引入刚才新建的项目

   <dependency>
            <groupId>com.sf</groupId>
            <artifactId>baidu-id-starter</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

4.2 将第1步项目中的WORKER_NODE.xml拷贝至当前项目

4.3 配置yml

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

4.4 数据库创建表

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: ACTUAL or CONTAINER',
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;

4.5 使用

直接autowired即可
