Servlet中init-param and content-param
在Servlet中
this.getServletConfig().getInitParamter("parma");//获取Servelt中的init-param的值
this.getServletConfig().getServletContext().getInitParamter("school");//获取Servlet中的content-param的值
在JSP中
config.getInitParamter("parma");//获取Servelt中的init-param的值
config.getServletContext().getInitParamter("school");//获取Servlet中的content-param的值
xml中设置的值
init-param只能在一个servlet中读取,而content-param各个servlet和jsp都能访问,前者点击单个servlet-->add child-->init-param
后者web-app-->add child-->content-param
