ServletContext获取多个servlet公共参数

web.xml:

 <context-param>
  	<param-name>context-param</param-name>
  	<param-value>context-value</param-value>
  </context-param>

获取方式：

ServletContext servletContext = this.getServletContext();
servletContext.getAttribute("name");
System.out.println(servletContext.getAttribute("name"));
