public class PropertiesTest1 {
    public static void main(String[] args) throws IOException {
        readProperties();
    }

    public static void readProperties() throws IOException {
        // 1.创建Properties对象
        Properties ps = new Properties();
        // 2.创建字节输入流对象 
        InputStream in = new FileInputStream(new File("Properties文件解析/resources/user.properties"));
//        InputStream in = new FileInputStream(new File("resources/user.properties"));
        // 3.将字节文件加载到map中
        ps.load(in);
        // 4.通过key读取值
        String username = ps.getProperty("username");
        String password = ps.getProperty("password");
        System.out.println("username = " + username + "," + "password = " + password);
    }
}


为什么我没有注释的这一行那个文件路径运行程序结果是找不到该文件?
这样也不行:
          
day01_基础加强/src/Properties文件解析/resources/user.properties

src/Properties文件解析/resources/user.properties

就这样都是不行的,除了是直接将资源文件夹放在根目录下,然后 resources/user.properties
