项目引用的jar包数了一下将近100个，直接引用其他项目的pom文件自然也不适合。所以有了下面的代码，把使用到的jar包放在文件夹中，运行一下，自动生成。 import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.util.jar.JarInputStream; import java.util.jar.Manifest; import org.dom4j.Element; import org.dom4j.dom.DOMElement; import org.jsoup.Jsoup; import com.alibaba.fastjson.JSONObject; public class makePom { public static void main(String[] args) throws FileNotFoundException, IOException { Element dependencys = new DOMElement("dependencys"); File dir = new File("F:/lib"); //需生成pom.xml 文件的 lib路径 for (File jar : dir.listFiles()) { JarInputStream jis = new JarInputStream(new FileInputStream(jar)); Manifest mainmanifest = jis.getManifest(); jis.close(); String bundleName = mainmanifest.getMainAttributes().getValue( "Bundle-Name"); String bundleVersion = mainmanifest.getMainAttributes().getValue( "Bundle-Version"); Element ele = null; System. out.println(jar.getName()); StringBuffer sb = new StringBuffer(jar.getName()); if (bundleName != null) { bundleName = bundleName.toLowerCase().replace( " ", "-"); sb.append(bundleName+ "\t").append(bundleVersion); ele = getDependices(bundleName, bundleVersion); System. out.println(sb.toString()); System. out.println(ele.asXML()); } if (ele == null || ele.elements().size() == 0) { bundleName = ""; bundleVersion = ""; String[] ns = jar.getName().replace( ".jar", "").split("-"); for (String s : ns) { if (Character.isDigit(s.charAt(0))) { bundleVersion += s + "-"; } else { bundleName += s + "-"; } } if (bundleVersion.endsWith("-")) { bundleVersion = bundleVersion.substring( 0, bundleVersion.length() - 1); } if (bundleName.endsWith("-")) { bundleName = bundleName.substring( 0, bundleName.length() - 1); } ele = getDependices(bundleName, bundleVersion); sb.setLength( 0); sb.append(bundleName+ "\t").append(bundleVersion); System. out.println(sb.toString()); System. out.println(ele.asXML()); } ele = getDependices(bundleName, bundleVersion); if (ele.elements().size() == 0) { ele. add(new DOMElement("groupId").addText("not find")); ele. add(new DOMElement("artifactId").addText(bundleName)); ele. add(new DOMElement("version").addText(bundleVersion)); } dependencys. add(ele); System. out.println(); } System. out.println(dependencys.asXML()); } public static Element getDependices(String key, String ver) { Element dependency = new DOMElement("dependency"); // 设置代理 // System.setProperty("http.proxyHost", "127.0.0.1"); // System.setProperty("http.proxyPort", "8090"); try { String url = "http://search.maven.org/solrsearch/select?q=a%3A%22" + key + "%22%20AND%20v%3A%22" + ver + "%22&rows=3&wt=json"; org.jsoup.nodes.Document doc = Jsoup.connect(url).ignoreContentType( true).timeout(30000).get(); String elem = doc.body().text(); JSONObject response = JSONObject.parseObject(elem).getJSONObject( "response"); if (response.containsKey("docs") && response.getJSONArray("docs").size() > 0) { JSONObject docJson = response.getJSONArray( "docs").getJSONObject(0); Element groupId = new DOMElement("groupId"); Element artifactId = new DOMElement("artifactId"); Element version = new DOMElement("version"); groupId.addText(docJson.getString( "g")); artifactId.addText(docJson.getString( "a")); version.addText(docJson.getString( "v")); dependency. add(groupId); dependency. add(artifactId); dependency. add(version); } } catch (Exception e) { e.printStackTrace(); } return dependency; } }生成之后可能会引用一些依赖，不想要这些依赖的话可以在pom.xml加上这些就不引用依赖了 * * |
