使用maven遍历所有类并提取信息。

import java.io.File;
import java.io.IOException;

import java.util.Enumeration;

public class ClassScanner {

        List<Class<?>> classes = getAllClasses("com.example"); // 替换为你的项目包名
        for (Class<?> clazz : classes) {
            // 在这里可以对每个类进行处理，提取所需的信息
            System.out.println(clazz.getName());
        }
    }

    public static List<Class<?>> getAllClasses(String packageName) throws IOException, ClassNotFoundException {

            classes.addAll(findClasses(file, packageName));
        }
        return classes;
    }

    private static List<Class<?>> findClasses(File directory, String packageName) throws ClassNotFoundException {
        List<Class<?>> classes = new ArrayList<>();
        if (!directory.exists()) {

                classes.addAll(findClasses(file, packageName + "." + file.getName()));
            } else if (file.getName().endsWith(".class")) {
