SQL> select sys_guid() from dual ; 

SYS_GUID() 
--------------------------------

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()); 
}
