java获取配置文件后的返回值
java获取配置文件后的返回值问题,systemConfi该如何赋值
public class SystemConfigUtil{ public static SystemConfig getSystemConfig() { InputStream inputStream = SystemConfigUtil.class.getClassLoader().getResourceAsStream("config.properties"); Properties p = new Properties(); try{ p.load(inputStream); }catch(IOException e){ e.printStackTrace(); } // System.out.println("FilePath"+p.getProperty("FilePath")+",ImagePath"+p.getProperty("ImagePath")+",PortraitPath"+p.getProperty("PortraitPath")); return systemConfig;//该如何赋值....初学不是很懂 } }import java.io.IOException;import java.util.Properties;import org.omg.CORBA.portable.InputStream;/** * 我猜测这是一个配置文件类 * @author qian.xu * */public class SystemConfigUtil{ private static Properties p = null; private static SystemConfigUtil systemConfigUtil = new SystemConfigUtil(); //这里用到了单例模式,所以私有化构造方法 private SystemConfigUtil(){ } /** * 对外公开的方法,是SystemConfigUtil获得配置文件 * @return systemConfigUtil */ public static SystemConfigUtil getSystemConfig() { InputStream inputStream = (InputStream) SystemConfigUtil.class.getClassLoader() .getResourceAsStream("config.properties"); try{ if(systemConfigUtil.p==null){ systemConfigUtil.p.load(inputStream);//如果systemConfigUtil中p没有东西给他加上东西 //否则返回 } }catch(IOException e){ e.printStackTrace(); } // System.out.println("FilePath"+p.getProperty("FilePath")+",ImagePath"+p.getProperty("ImagePath")+",PortraitPath"+p.getProperty("PortraitPath")); return systemConfigUtil;// } }
