路径路径路径

      File file = new File("");
        String filePath = file.getCanonicalPath();
        System.out.println(filePath);

        //当前项目下xml文件夹
        File file1 = new File("");
        String filePath1 = file1.getCanonicalPath()+File.separator+"xml\\";
        System.out.println(filePath1);

        //获取类加载的根路径
        File file3 = new File(this.getClass().getResource("/").getPath());
        System.out.println(file3);
       
       
        String path = this.getClass().getResource("/").getPath();
        String[]  paths = path.split("WEB-INF");
        path = paths[0] + "upload/";
        System.out.println(path);
        //获取当前类的所在工程路径
        File file4 = new File(this.getClass().getResource("").getPath());
        System.out.println(file4);

        //获取所有的类路径 包括jar包的路径
        System.out.println(System.getProperty("java.class.path"));
