<!--加载spring上下文配置-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring.xml</param-value>
</context-param>

<!--1,Spring监听器-->

<!--1.1 web容器启动时触发的监听器,在web容器启动时,加载类似上面"content-param"标签指定的配置文件-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--1.2 http请求的监听器:如果需要配置request,session,globalSession作用域的bean,则需要配置以下监听器-->
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

<!--2,springmvc的dispatcherServlet-->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<!--是否使用异步处理(3.0新特性),提高并发能力-->
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!--3,对静态资源的访问交给defaultServlet处理,放在dispatcherServlet的mapping之前,不需要经过dispatcherServlet来提高性能-->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>
</servlet-mapping>

<!--4,乱码问题处理-->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<!--初始化编码方式-->
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>

</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>
