读取properties文件的信息

1、properties配置文件的信息

fcsimage_path=C://FCSImage

2、Java代码

public final class Config {

    private static final Object lock = new Object();

    private static volatile Properties config;

    private Config(){}

    private static Properties getInstance(){

        if (config == null)

        {

            //double lock check

            synchronized (lock) { // declare a private static Object to use for mutex

                if( config == null ){     // have to do this inside the sync

                    config = new Properties();

                }

            }

            try {

                config.load(Config.class.getClassLoader().getResourceAsStream("common.properties"));

            } catch (IOException e) {

                e.printStackTrace();

            }

        }

        return config;

    }

    public static String fcsimage_path() {

        return getInstance().getProperty("fcsimage_path");

    }

}
