MyEclipse 8.0 过期怎么办

1、新建一个工程 这里我取名为asc

2、在工程下新建一个class类 这里叫MyEclipseGen

3、MyEclipseGen文件里面的代码 

import java.text.DecimalFormat;

 import java.text.NumberFormat;

 import java.text.SimpleDateFormat;

 import java.util.Calendar;

 public class MyEclipseGen {

  public static final void main(String[] args) {

   String id = "liuchao"; // 可更给为您的名字

   String num = "999";// 许可证数量

   System.out.println(getSerial(id, "100", num, false));

  }

  public static String getSerial(String userId, String version, String licenseNum, boolean selected) {

   Calendar cal = Calendar.getInstance();

   cal.add(1, 3);

   cal.add(6, -1);

   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() :

        "-1712250";//表示20171205，可改为自己需要的日期

   String type = "YE3MB-";

   String need = (new StringBuffer(String.valueOf(userId.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(userId).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);

  }

 }

4、然后运行这个代码  里面的用户名我命名为liuchao  ，日期也在第二个注释的位置可以自行修改哦 。运行结果就为注册码了。

5、点击windows下的Preferences ->MyEclipse->Subscription

6、在右侧点击Enter Subscription 输入用户名  和注册码即可
