項目引用的jar包數了一下將近100個，直接引用其他項目的pom文件自然也不適合。所以有了下面的代碼，把使用到的jar包放在文件夾中，運行一下，自動生成。

1. import java.io.File;
2. import java.io.FileInputStream;
3. import java.io.FileNotFoundException;
4. import java.io.IOException;
5. import java.util.jar.JarInputStream;
6. import java.util.jar.Manifest;
7. import org.dom4j.Element;
8. import org.dom4j.dom.DOMElement;

11. public class makePom {
12. public static void main(String[] args) throws FileNotFoundException, IOException {
13. Element dependencys = new DOMElement("dependencys");
14. File dir = new File("F:/lib"); //需生成pom.xml 文件的 lib路徑
15. for (File jar : dir.listFiles()) {
16. JarInputStream jis = new JarInputStream(new FileInputStream(jar));
17. Manifest mainmanifest = jis.getManifest();
18. jis.close();
19. String bundleName = mainmanifest.getMainAttributes().getValue("Bundle-Name");
20. String bundleVersion = mainmanifest.getMainAttributes().getValue("Bundle-Version");
21. Element ele = null;
22. System.out.println(jar.getName());
23. StringBuffer sb = new StringBuffer(jar.getName());
24. if (bundleName != null) {
25. bundleName = bundleName.toLowerCase().replace(" ", "-");
26. sb.append(bundleName+"\t").append(bundleVersion);
27. ele = getDependices(bundleName, bundleVersion);
28. System.out.println(sb.toString());
29. System.out.println(ele.asXML());
30. }
31. if (ele == null || ele.elements().size() == 0) {
32. bundleName = "";
33. bundleVersion = "";
34. String[] ns = jar.getName().replace(".jar", "").split("-");
35. for (String s : ns) {
36. if (Character.isDigit(s.charAt(0))) {
37. bundleVersion += s + "-";
38. } else {
39. bundleName += s + "-";
40. }
41. }
42. if (bundleVersion.endsWith("-")) {
43. bundleVersion = bundleVersion.substring(0, bundleVersion.length() - 1);
44. }

57. ele.add(new DOMElement("groupId").addText("not find"));
58. ele.add(new DOMElement("artifactId").addText(bundleName));
59. ele.add(new DOMElement("version").addText(bundleVersion));
60. }
61. dependencys.add(ele);
62. System.out.println();

78. Element groupId = new DOMElement("groupId");
79. Element artifactId = new DOMElement("artifactId");
80. Element version = new DOMElement("version");
81. groupId.addText(docJson.getString("g"));
82. artifactId.addText(docJson.getString("a"));
83. version.addText(docJson.getString("v"));
84. dependency.add(groupId);
85. dependency.add(artifactId);
86. dependency.add(version);
87. }
88. } catch (Exception e) {
89. e.printStackTrace();
90. }
91. return dependency;
92. }
93. }

生成之後可能會引用一些依賴，不想要這些依賴的話可以在pom.xml加上這些就不引用依賴了

<exclusions>
<exclusion>
<groupId>*</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
