为什么config.getInitParameter(String)总是null在以下代码示例中返回？

public void init(ServletConfig config) throws ServletException
{
    super.init(config);
    filename = config.getInitParameter("addressfile");

这是web.xml文件

<servlet>
<servlet-name>ListManagerServlet</servlet-name>
<servlet-class>savva.listmanagerservlet.ListManagerServlet</servlet-class>
<init-param>
    <param-name>addressfile</param-name>
    <param-value>d:\temp\demo.txt</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>ListManagerServlet</servlet-name>
<url-pattern>/ListManagerServlet</url-pattern>
</servlet-mapping>
