java讀取resource目錄下的配置文件

1：配置resource目錄 下的文件

host: 127.0.0.1
port: 9300

2:讀取 / 代表resource目錄

        InputStream in = this.getClass().getResourceAsStream("/config.properties");
        Properties properties = new Properties();
        try {
            properties.load(in);
        } catch (IOException e) {
            e.printStackTrace();
        }
        String host 
 
= properties.getProperty("host");
        String port = properties.getProperty("port");
        int intport = Integer.parseInt(port);
