创建maven项目引入依赖:

        <dependency>
            <groupId>org.apache.shardingsphere</groupId>
            <artifactId>shardingsphere-jdbc-core</artifactId>
            <version>5.1.1</version>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.24</version>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>com.github.yitter</groupId>
            <artifactId>yitter-idgenerator</artifactId>
            <version>1.0.6</version>
        </dependency>

 

编写主键生成类

public class CarautoKeyGen implements KeyGenerateAlgorithm {

    final static short method = 1;

    @Override
    public Comparable<?> generateKey() {
        return YitIdHelper.nextId();
    }

    @Override
    public void init() {
        IdGeneratorOptions options = new IdGeneratorOptions();
        options.WorkerIdBitLength = 6;
        options.SeqBitLength = 10;
        options.BaseTime = System.currentTimeMillis();
        options.Method = method;
        options.WorkerId = 2;
        YitIdHelper.setIdGenerator(options);
    }

    @Override
    public String getType() {
        return "CarautoKeyGen";
    }
}

添加一个SPI配置

resources依次创建目录META-INF与services

在services目录下创建文件

org.apache.shardingsphere.sharding.spi.KeyGenerateAlgorithm

文件内容为您的Java类

我这里就只有一个 所以就写了

CarautoKeyGen

打包完成以后放到Sharding-Proxy程序目录下的Lib目录内并给予执行权限，

同时漂移ID的jar文件也要放入Lib目录内并给予执行权限
