用原来注册的subscriber 名称为参数获取新的注册码

1、拷贝代码并编译

12         String subscriptionCode = getSubscriptionCode(subscriber, version , licenseNum ,true);        
13         System.out.println(subscriptionCode);  //gLR8ZO-655055-62677056522757051

55         return String.valueOf(ac);      
56         }
57 }

 

2、运行结果

sLR8ZO-655055-7756685919294619

3、单击菜单栏 MyEclipse——》subscription information...

　　输入subscriber：、以及subscription code：运行结果
