MyEclipse 开发工具
新建一个工程 这里我取名为asc
在工程下新建一个class类 这里叫MyEclipseGen
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); } }
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。
点击windows下的Preferences ->MyEclipse->Subscription
在右侧点击Enter Subscription 输入用户名 和注册码即可
该方法是限于个人学习 使用。
修改用户名 和日期俩个地方 日期1712250 表示为2017年12月5日
