maven项目中pom.xml快速生成

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

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