java程式碼

private static String getRestfulAddress() {
        Properties pps = new Properties();
        try {
            String dir2 
 
= System.getProperty("catalina.home") + 
                    File.separator +"lib" + File.separator 
                    + "emc" + File.separator + "test.properties";
            FileInputStream fs = new FileInputStream(dir2);
            InputStream in = new BufferedInputStream (fs);
            pps.load(in);
            String restfulAddress 
 
= pps.getProperty("restfulAddress");
            in.close();
            return restfulAddress;
        } catch (Exception e) {
            e.printStackTrace();
        }  
        return null;
