JAVA中的路径问题-获取包内文件路径

package com.gblfy.controller;

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

public class A {

    public static void main(String[] args) throws Exception {
        URL url = A.class.getResource("");
        String path = url.getPath();
        File file = new File(path + "innerFile.txt");
        System.out.println("配置文件的路径为：" + file.getAbsolutePath());
        String replace = file.getAbsolutePath().replace("target"+File.separator+"classes"+File.separator, "");
        System.out.println("配置文件的路径处理后：" + replace);
    }
}
