JavaWeb——Day03_2遇到的问题！

在练习servletcontext的第四个功能——资源加载的时候。

按照代码来敲，遇到的了如下问题。

源码是这样的：

但是我按照上面的做法，敲了。

运行出现报错！

然后网上查找原因，发在在这个博客里面有解决方式，

  解决方法：

 原始代码：为注释部分

   Properties props = new Properties();
         try
         {
             // FileInputStream fis = new FileInputStream(configFilePath);
             // InputStreamReader reader = new InputStreamReader(fis, "UTF-8");
             InputStream inputStream = new BufferedInputStream(new FileInputStream(configFilePath));
             props.load(inputStream);
             Iterator it = props.keySet().iterator();
             while (it.hasNext())
             {
                 // String key = (String) it.next();
                 String key = (String) it.next();
                 String value = props.get(key).toString();
                 value = new String(value.getBytes("ISO8859-1"), "UTF-8");
                 configMap.put(key, value);
             }
         }
         catch (Exception ex)
         {
             logger.error(ex.getMessage());
         }
