利用java.util.Properties从properties文件读入properties

java 代码

// reads the properties from the property file
       Properties props = new Properties();
       try {
           props.load(new FileInputStream(PROPERTIES_FILE));
       } catch (IOException ex) {
           System.out.println("error configuring unit tests");
           ex.printStackTrace();
       }

       SFTP_HOSTNAME = props.getProperty("server");
       InetAddress temp = null;
       try {
           temp = InetAddress.getByName(SFTP_HOSTNAME);
       } catch (UnknownHostException ex) {
           System.out.println("error resolving host " + SFTP_HOSTNAME);
       }
       SFTP_HOST = temp;

       USERNAME = props.getProperty("username");
       PASSWORD = props.getProperty("password");
