通过写Java代码来对MyEclipse进行注册

最近使用MyEclipse 7.5.0时，发现它30试用期快过了，提示我要注册。

其实，不用麻烦从网上搜索那些存在的注册码的，这样操作：

在MyEclipse中新建一个工程，导入下面的文件:

MyEclipseGen.java

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class MyEclipseGen { 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). 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."; 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 MyEclipseGen() {    super(); } public static void main(String[] args) {    try {     System.out.println("please input register name:");     BufferedReader reader = new BufferedReader(new InputStreamReader(       System.in));     String userId = null;     userId = reader.readLine();     MyEclipseGen myeclipsegen = new MyEclipseGen();     String res = myeclipsegen.getSerial(userId, "5");     System.out.println("Serial:" + res);     reader.readLine();    } catch (IOException ex) {    } } }

运行该代码，在控制台中会出现： please input register name: ×××××（你的name,随便什么） 即生成序列号： ××××× ××××× ×××××...

进入myeclipse,在菜单中选择 Myeclipse->Subscription Information 然后 输入Subscriber和Subscription code即可。

sub

使用时间一般很长的。 哈……自己把自己破解了，爽！
