uuid生成器

有时候我们需要自己控制uuid的生成，这里使用的是JUG采用的是LGPL开源协议
maven依赖

<dependency>            <groupId>org.safehaus.jug</groupId>            <artifactId>jug</artifactId>            <version>2.0.0</version>            <classifier>lgpl</classifier></dependency>

使用方法

public static String getUUID() {        UUIDGenerator generator = UUIDGenerator.getInstance();        return generator.generateTimeBasedUUID().toString();    }public static String getUUID32() {        UUIDGenerator generator = UUIDGenerator.getInstance();        String uid = generator.generateTimeBasedUUID().toString();        uid = StringUtils.replace(uid, "-", "");        return uid;    }
