2. java生成uuid

Java代码 
import java.util.UUID;  
 
public class IdGenerate {  
 
public static String getUUIDString() {  
   String id = UUID.randomUUID().toString();  
   id = id.replace("-", "");  
   return id;  
}  
 
public static void main(String[] args) {  
   System.out.println(IdGenerate.getUUIDString());  
}  
 
} 

import java.util.UUID;

public class IdGenerate {

public static String getUUIDString() {
   String id = UUID.randomUUID().toString();
   id = id.replace("-", "");
   return id;
}

public static void main(String[] args) {
   System.out.println(IdGenerate.getUUIDString());
}
