uuid生成器

有時候我們需要自己控制uuid的生成，這裏使用的是JUG採用的是LGPL開源協議
maven依賴

<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;
    }
