今天MyEclipse提示過期了,MyEclipse Trial Expired.

網上找到了一個註冊類可以生成Myeclipse註冊碼.

1. import java.io.*;
5. public class MyEclipseGen {
7. 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.";
11. public String getSerial(String userId, String licenseNum) {
13. java.util.Calendar cal = java.util.Calendar.getInstance();
15. cal.add(1, 3);
17. cal.add(6, -1);
19. java.text.NumberFormat nf = new java.text.DecimalFormat("000");
21. licenseNum = nf.format(Integer.valueOf(licenseNum));
23. String verTime = new StringBuilder("-").append(
25. new java.text.SimpleDateFormat("yyMMdd").format(cal.getTime()))
27. .append("0").toString();
29. String type = "YE3MP-";
31. String need = new StringBuilder(userId.substring(0, 1)).append(type)
33. .append("300").append(licenseNum).append(verTime).toString();
35. String dx = new StringBuilder(need).append(LL).append(userId)
37. .toString();
39. int suf = this.decode(dx);
41. String code = new StringBuilder(need).append(String.valueOf(suf))
43. .toString();
45. return this.change(code);
47. }
51. private int decode(String s) {
53. int i;
55. char[] ac;
57. int j;
59. int k;
61. i = 0;
63. ac = s.toCharArray();
65. j = 0;
67. k = ac.length;
69. while (j < k) {
71. i = (31 * i) + ac[j];
73. j++;
75. }
77. return Math.abs(i);
79. }
83. private String change(String s) {
85. byte[] abyte0;
87. char[] ac;
89. int i;
91. int k;
93. int j;
95. abyte0 = s.getBytes();
97. ac = new char[s.length()];
99. i = 0;
101. k = abyte0.length;
103. while (i < k) {
105. j = abyte0[i];
107. if ((j >= 48) && (j <= 57)) {
109. j = (((j - 48) + 5) % 10) + 48;
111. } else if ((j >= 65) && (j <= 90)) {
113. j = (((j - 65) + 13) % 26) + 65;
115. } else if ((j >= 97) && (j <= 122)) {
117. j = (((j - 97) + 13) % 26) + 97;
119. }
121. ac[i] = (char) j;
123. i++;
125. }
127. return String.valueOf(ac);
129. }
133. public MyEclipseGen() {
135. super();
137. }
141. public static void main(String[] args) {
143. try {
145. System.out.println("please input register name:");
147. BufferedReader reader = new BufferedReader(new InputStreamReader(
149. System.in));
151. String userId = null;
153. userId = reader.readLine();
155. MyEclipseGen myeclipsegen = new MyEclipseGen();
157. String res = myeclipsegen.getSerial(userId, "0");
159. System.out.println("Serial:" + res);
161. reader.readLine();
163. } catch (IOException ex) {
165. }
167. }
169. }

運行後效果如下:

修改String res = myeclipsegen.getSerial(userId, "20"); 中"20"為"0"可以變成Number of Licenses為Unlimited.

然後

然後將剛才生成的序列號輸入

點擊下面的Finish即可

代碼測試過了，可行！

從Myeclipse--》subscription information 即可進入update subscription界面。

ok，現在可以了吧？恭喜你！
