Myeclipse update subscription问题

1、运行MyEclipse，弹出“Subscription Key Information”框。

2、点击“Enter Subscription”,进入“Update Subscription”

3、输入Subscriber 和Subscription Code:

MaYong

ZLR8ZO-655444-54678656985359684

输入后页面没有报错，但是“Finish”也不能操作，说明注册码不正确。

4、整理别人提供的MyEclipseKey生成器，代码如下(代码格式有点混乱，可直接拷贝)：

import java.text.DecimalFormat;import java.text.NumberFormat;import java.text.SimpleDateFormat;import java.util.Calendar;

public class MyEclipseKeyGen {  public static final void main(String[] args){          String subscriber = "tianshansangong";  //subscriber        String licenseNum = "500";  //Number of Licenses        String version = "100"; //版本号        String subscriptionCode = getSubscriptionCode(subscriber, version , licenseNum ,true);        System.out.println(subscriptionCode);  //gLR8ZO-655055-62677056522757051    }      public static String getSubscriptionCode(String subscriber, String version,              String licenseNum, boolean selected) {          Calendar cal = Calendar.getInstance();          cal.add(1, 3);  //年份加三年        cal.add(6, -1);  //日期减一        //当前日期20141226，到期日期则为20171225        NumberFormat nf = new DecimalFormat("000");          licenseNum = nf.format(Integer.valueOf(licenseNum));          String verTime = selected ? (new StringBuffer("-")).append(                  (new SimpleDateFormat("yyMMdd")).format(cal.getTime())).append(                  "0").toString() : "-0812310";          String type = "YE3MB-";          String need = (new StringBuffer(String.valueOf(subscriber.substring(0, 1))))                  .append(type).append(version).append(licenseNum)                  .append(verTime).toString();          String dx = (new StringBuffer(String.valueOf(need)))                  .append(                          "Decompiling this copyrighted software is a violation of both your license agreement and the Digital Millenium Copyright Act of 1998 (http://www.loc.gov/copyright/legislation/dmca.pdf). Under section 1204 of the DMCA, penalties range up to a $500,000 fine or up to five years imprisonment for a first offense. Think about it; pay for a license, avoid prosecution, and feel better about yourself.")                                            .append(subscriber).toString();          int suf = decode(dx);          String code = (new StringBuffer(String.valueOf(need))).append(                  String.valueOf(suf)).toString();          return change(code);      }     private static int decode(String s) {          int i = 0;          char ac[] = s.toCharArray();          int j = 0;          for (int k = ac.length; j < k; j++)              i = 31 * i + ac[j];         return Math.abs(i);      }     private static String change(String s) {          byte abyte0[] = s.getBytes();          char ac[] = new char[s.length()];          int i = 0;          for (int k = abyte0.length; i < k; i++) {              int j = abyte0[i];              if (j >= 48 && j <= 57)                  j = ((j - 48) + 5) % 10 + 48;              else if (j >= 65 && j <= 90)                  j = ((j - 65) + 13) % 26 + 65;              else if (j >= 97 && j <= 122)                  j = ((j - 97) + 13) % 26 + 97;              ac[i] = (char) j;          }         return String.valueOf(ac);      }}

5、生成了

Subscriber：tianshansangong

Subscription Code：gLR8ZO-655055-62677056522757051

可直接拷贝这个使用

6、填入上面的窗口即可。

或者点击“window”->"Preferences"->MyEclipse Blue Edition->"Subscription"输入即可。
