使用ClassLoader加载配置文件

@Test
    public void test2() throws Exception {
        Properties pro = new Properties();
        //读取配置文件的方式一：
        /*FileInputStream fis = new FileInputStream("src/jdbc.properties");
        pro.load(fis);*/
        //读取配置文件的方式二：
        ClassLoader classLoader = ClassLoaderTest.class.getClassLoader();
        InputStream is = classLoader.getResourceAsStream("jdbc.properties");
        pro.load(is);
        String username = pro.getProperty("username");
        String password = pro.getProperty("password");
        System.out.println("username:"+username+",password:"+password);
    }
