MyEclipse提示your trial period has expired时，如何手动获取MyEclipse注册码！

1、建立JavaProject，随便命名，只要符合规则就行。

2、在刚刚建好的项目中右击src，新建一个class类，命名为MyEclipseGen，把.java里本来有的代码全部删掉，再把本文最下面的代码复制到该类中，保存，运行，当控制台出现please input register name:时，自定义输入一串字符串，然后回车，就会获取到一串注册码，然后停止项目的运行，复制注册码。

如下图所示：

3、然后MyEclipse--> SubscriptionInformation，在弹出框的中Subscriber中输入你刚刚输入的字符串，在SubsctiptionCode中粘贴刚刚输出的注册码即可。

如果成功的话应该会发现如下提示，点击finish结束，恭喜你成功啦！然后重启MyEclipse就不会再出现该提示框啦！
