java springboot 获取类路径方式集合

//spring boot获取类路径 获取当前类路径
        String springbooPath1 = ClassUtils.getDefaultClassLoader().getResource("").getPath();
        System.out.println("springbooPath1:"+springbooPath1);
        String springbooPath2 = ResourceUtils.getURL("classpath:").getPath();
        System.out.println("springbooPath2:"+springbooPath2);
        //不能这样写
       // String springbooPath3 = ClassUtils.getDefaultClassLoader().getResource("/").getPath();

        //环境变量中的属性
        Properties properties = System.getProperties();
        //jar包所在的路径
        String dir = properties.getProperty("user.dir");
        System.out.println("dir:"+dir);
        String realPath = properties.getProperty("realPath");
        System.out.println("realPath:"+realPath);
        String jarWholePath = properties.getProperty("jarWholePath");
        System.out.println("jarWholePath:"+jarWholePath);

        String protectionDomain = MonitorController.class.getProtectionDomain().getCodeSource().getLocation().getFile();
        System.out.println("protectionDomain:"+protectionDomain);

        //class 获取方式 获取当前类文件所在路径
        String classPath = this.getClass().getResource("").getPath();
        System.out.println("classPath:"+classPath);
        //class 获取方式 获取当前类路径
        String classPath2 = this.getClass().getResource("/").getPath();
        System.out.println("classPath2:"+classPath2);

        //通过类加载器获取jar包的绝对路径
        String classLoaderPath = MonitorController.class.getClassLoader().getResource("").getPath();
        System.out.println("classLoaderPath:"+classLoaderPath);
        //不能这样写
//        String classLoaderPath2 = MonitorController.class.getClassLoader().getResource("/").getFile();

        System.out.println("contextClassPath1:"+contextClassPath1.getPath());
        //不能这样写
//        URL contextClassPath2 = Thread.currentThread().getContextClassLoader().getResource("/");
