您可以在jar文件中添加多个jar,然后启动该jar文件

import java.io.File;
import java.net.URL;
import java.net.URLClassLoader;

public class MultipleJarExample {
    public static void main(String[] args) {
        try {
            File jarDir = new File("path/to/jar/directory");
            URL[] jars = jarDir.listFiles(new FilenameFilter() {
                public boolean accept(File dir, String name) {
                    return name.endsWith(".jar");
                }
            }).map(new Function<File, URL>() {
                public URL apply(File file) {
                    try {
                        return file.toURI().toURL();
                    } catch (MalformedURLException e) {
                        throw new RuntimeException(e);
                    }
                }
            }).toArray(new URL[0]);

            URLClassLoader classLoader = new URLClassLoader(jars, MultipleJarExample.class.getClassLoader());
            Class<?> clazz = classLoader.loadClass("com.example.MyClass");
            Object instance = clazz.getConstructor().newInstance();
            Method method = clazz.getMethod("myMethod");
            method.invoke(instance);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
