此問題解決方案有兩種：
第一種：下載MyEclipse註冊機，地址：http://download.csdn.net/detail/zzq2yz1314/4756537
第二種：手動生成註冊碼，步驟如下：
（一）新建Java Project，任意命名。
![]()
（二）在工程中的 src 文件夾中，新建class ，命名爲：MyEclipseGen。
（三）將新建的類中自動生成的代碼完全清除，複製以下代碼粘貼進去：

}

}
public MyEclipseGen() {
super();
}
public static void main(String[] args) {
try {
System.out.println("please input register name:");
BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));
// BufferedReader 從字符輸入流中讀取文本，緩衝各個字符，從而實現字符、數組和行的高效讀取
String userId = null;
userId = reader.readLine(); // String readLine() 讀取一個文本行
MyEclipseGen myeclipsegen = new MyEclipseGen();
String res = myeclipsegen.getSerial(userId, "20");
System.out.println("Serial:" + res);
reader.readLine();
} catch (IOException ex) {
}
}
}

（四）運行上述程序，控制檯輸入任意字符串，以回車結束：
（五）在菜單欄中，鼠標點擊 MyEclipse --> Subscription Information ，將控制檯輸入的 register name
和輸出的 Serial 分別複製並粘貼在Subscriber和Subscription Code中，點擊Finish完成註冊。
