java .properties 读取配置信息

注意，.properties文件放在根目录即可。

String classpath = Thread.currentThread().getContextClassLoader().getResource("/").getPath();  //获取根目录
  		String fileName = classpath + "truths.properties"; //配置文件名称
  		Properties p = new Properties();
  		FileInputStream fis;
  		try {
  			fis = new FileInputStream(fileName);
  			p.load(fis); //初始化
  			return p.getProperty("server"); //key名称
  		} catch (Exception e) {
  			e.printStackTrace();
  		}

防止中文乱码以及防止%20 发生*.

String classpath = Thread.currentThread().getContextClassLoader().getResource("/").getPath();  
  			classpath = URLDecoder.decode(classpath,"UTF-8 ");   //liunx 环境下，防止" " 转化为%20 而路径报错  
  			String fileName = classpath + "truths.properties";
  	  		Properties p = new Properties();
  	  		FileInputStream fis = new FileInputStream(fileName);
  	  		//防止中文乱码/.
  			BufferedReader bf = new BufferedReader(new InputStreamReader(fis));  
  			p.load(bf);
  			p.getProperty("server");

简单暴力.     直接使用.
