字节流搭配Properties

java解析.properties文件专门有个工具类：Properties
`public class WebServer {
static Properties p = new Properties();
static
{ _//配置web服务的端口

    _**try **{<br />            FileInputStream in=**new **FileInputStream(**"./config.properties"**);<br />            _p_.load((in));<br />            String port=_p_.getProperty(**"admin.port"**);<br />        } **catch **(FileNotFoundException e) {<br />            e.printStackTrace();<br />        } **catch **(IOException e) {<br />            e.printStackTrace();<br />        }
}<br />    _//web服务启动<br />    _**public  void **start()<br />    {<br />        SimpleServer server= HttpUtil._createServer_(Integer._parseInt_(_p_.getProperty(**"admin.port"**)));<br />        server.start();<br />        System.**_out_**.println(**"服务器启动"**);<br />        Action action=(request,reponse)-><br />            {<br />                reponse.write(**"hello web"**);<br />            };<br />        server.addAction(**"/admin"**,action);<br />    }
**public static void **main(String[] args) {<br />        WebServer  webServer  = **new  **WebServer();<br />        webServer.start();<br />    }
