如何使用web.xml配置参数，并在serlvet取得该值

1. 首先在web.xml进行配置：  

[html] view plaincopy

1. <servlet-name>TestServlet</servlet-name>  
2.     <servlet-class>test.TestServlet</servlet-class>  
3.       <init-param>  
4.    <param-name>charset</param-name>  
5.    <param-value>utf-8</param-value>  
6.   </init-param>  
7.   </servlet>  
8.   <servlet-mapping>  
9.     <servlet-name>TestServlet</servlet-name>  
10.     <url-pattern>/servlet/TestServlet</url-pattern>  
11.   </servlet-mapping>  

 

然后再serlvet进行取得：

String MyCharset = getInitParameter("charset");
