JSP读取Web.xml中的参数配置

  <servlet>
    <servlet-name>Password_Validate</servlet-name>
    <jsp-file>/check.jsp</jsp-file>
    <init-param>
    	<param-name>secret</param-name>
    	<param-value>macrotea</param-value>
    </init-param>
  </servlet>

  <servlet-mapping>
    <servlet-name>Password_Validate</servlet-name>
    <url-pattern>/check.jsp</url-pattern>
  </servlet-mapping>

 

如上配置后,当访问"/check.jsp"后,可以如下方式获取:

<%!
	ServletConfig config=getServletConfig();
%>
<%
	String secret=config.getInitParameter("secret");
	System.out.println(secret);
%>
