关于Myeclipse、eclipse的注册序列号，网上有很多。有注册机、注册码。。。但有时候IDE不给你面子，不承认你的序列号。而通过IDE 自己所写代码，自动生成序列号、破解它，所谓是以子之矛攻子之盾。

打开Myeclipse 或eclipse，新建一java项目，在src下新建一个类RegistrationKey。 java IDE之Myeclipse 6.X-9.0X/ eclipse 3.X 的序列号生成源码。

/**================================以下是源码 ====================================**/

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; ////////////////////////////////////////////////// /////用I/O实现IDE的注册码生成 ///////////////////////////////////////////////// public class RegistrationKey { private static final String LL = "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).

Think about it; pay for a license, avoid prosecution, and feel better about yourself."; public String getSerial(String userId, String licenseNum) { java.util.Calendar cal = java.util.Calendar.getInstance(); cal.add(1, 3); cal.add(6, -1); java.text.NumberFormat nf = new java.text.DecimalFormat("000"); licenseNum = nf.format(Integer.valueOf(licenseNum)); String verTime = new StringBuilder("-").append( new java.text.SimpleDateFormat("yyMMdd").format(cal.getTime())) .append("0").toString(); String type = "YE3MP-"; String need = new StringBuilder(userId.substring(0, 1)).append(type) .append("300").append(licenseNum).append(verTime).toString(); String dx = new StringBuilder(need).append(LL).append(userId) .toString(); int suf = this.decode(dx); String code = new StringBuilder(need).append(String.valueOf(suf)) .toString(); return this.change(code); } private int decode(String s) { int i; char[] ac; int j; int k; i = 0; ac = s.toCharArray(); j = 0; k = ac.length; while (j < k) { i = (31 * i) + ac[j]; j++; } return Math.abs(i); } private String change(String s) { byte[] abyte0; char[] ac; int i; int k; int j; abyte0 = s.getBytes(); ac = new char[s.length()]; i = 0; k = abyte0.length; while (i < k) { 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; i++; } return String.valueOf(ac); } public RegistrationKey() { super(); } public static void main(String[] args) { try { System.out.print("请输入您的用户名[英文字符]:"); BufferedReader reader = new BufferedReader(new InputStreamReader( System.in)); String userId = null; userId = reader.readLine(); RegistrationKey registrationKey = new RegistrationKey(); String res = registrationKey.getSerial(userId, "5"); System.out.println("您的软件序列号是:" + res); reader.readLine(); } catch (IOException ex) { System.out.println("IO出错了："+ex.getMessage()); } } }

我运行的结果：

请输入您的用户名[英文字符]:Ajun

您的软件序列号是:NLR8ZC-855550-69597456286953665
