<!-- DispatcherServlet有一些参数配置,默认情况下我们不需要指定,如果需要可通过<servlet>的<init-param>指定
1)namespace:DispatcherServlet对应的命名空间,默认为$servlet-name$-servlet,用于构造spring配置文件的路径;指定该属性后,配置文件对应的路径就变成了WEB-INF路径下namespace.xml文件
2)contextConfigLocation:如果DispatcherServlet上下文对应的spring配置文件有多个,则可使用该属性按照spring资源路径的方式指定,它和namespace有一样的功效
3)publishContext:一个boolean类型的属性,默认值是true,DispatcherServlet会根据该属性的值决定是否将webapplicationtext发布到servletContext属性列表中,以便调用者可借由servletContext找到webApplicationContext实例
4)publishEvents:一个boolean类型的属性,决定当DispatcherServlet处理完一个请求之后,是否需要向容器发布一个servletRequestHandleEvent事件,默认为true;如果容器中没有任何事件监听器,可以将此属性设定为false,以便提高运行性能
