web.xml解析

以下是本人项目中用到的配置参数等。

web.xml配置文件如下：

第一种参数在servlet里面可以通过getServletContext().getInitParameter("context/param")得到
第二种参数只能在servlet的init()方法中通过this.getInitParameter("param1")取得
init-param属于一个servlet所有,context-param属于整个应用程序所有 ,不仅是在servlet中可以得到,jsp文件中也可以得到.
在jsp中config就相当于这里的servletContext,<%=config.getServletContext().getInitParameter("...") %>.
action中ServletActionContext.getServletContext().getInitParameter("...").
