获取jar包中的class名

Main.java

import java.io.IOException;
import java.util.Enumeration;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class Main {

    public static void main(String[] args) throws IOException {
        // 项目中jar包所在物理路径
        String jarName = "/Users/admin/src/test.jar";
        JarFile jarFile = new JarFile(jarName);
        Enumeration<JarEntry> entrys = jarFile.entries();
        while (entrys.hasMoreElements()) {
            JarEntry jarEntry = entrys.nextElement();
            System.out.println(jarEntry.getName());
        }
    }
}
