java类中获取WEB-INF路径

 WEB-INF路径
 String path = WsTestBOImpl.class.getClass().getResource("/").getPath();
 path = path.substring(1, path.indexOf("classes"));

 web-inf 下面的classses路径（也就是src路径）
 String path = WsTestBOImpl.class.getClass().getResource("/").getPath();
 path = path.substring(1, path.length());

 --获取.properties配置文件的值--
 Properties p = new Properties();
 p.load(new FileInputStream(path + "aaa.properties"));
 String s = p.getProperty("name");
