Disruptor分布式id生成策略

需要的pom文件：

 <!-- 順序UUID -->
         <dependency>
            <groupId>com.fasterxml.uuid</groupId>
            <artifactId>java-uuid-generator</artifactId>
            <version>3.1.4</version>
         </dependency> 	

　　有時間順序：

import com.fasterxml.uuid.EthernetAddress;
import com.fasterxml.uuid.Generators;
import com.fasterxml.uuid.impl.TimeBasedGenerator;

public class KeyUtil {

	public static String generatorUUID(){
		TimeBasedGenerator timeBasedGenerator = Generators.timeBasedGenerator(EthernetAddress.fromInterface());
		return timeBasedGenerator.generate().toString();
	}
	
	public static void main(String[] args) {
		System.err.println(KeyUtil.generatorUUID());
		System.err.println(KeyUtil.generatorUUID());
	}
}

　　

 

 

以下兩種方式都不合適：
