基于 SpringMVC——web.xml基本配置

    <!--声明应用范围内的初始化参数-->
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/conf/conf-application.xml</param-value>
  </context-param>
  <!-- web监听 ,注册spring监听器，用于自动加载applicationContext.xml文件 -->
  <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener
        </listener-class>
  </listener>

  <!--声明过滤器，与一个实现javax.servlet.Filter接口的类相关联-->
  <filter>
    <filter-name>urlFilter</filter-name>
    <filter-class>com.base.filter.UrlFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>urlFilter</filter-name>
    <url-pattern>*.form</url-pattern>
  </filter-mapping>

    <!-- 配置SpringMVC入口servlet -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 启动后加载springMVC的配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:/conf/conf-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
          <servlet-name>springMVC</servlet-name>
          <url-pattern>*.form</url-pattern>
  </servlet-mapping>

  <!-- 会话超时长（分钟）  -->
  <session-config>
    <session-timeout>240</session-timeout>
  </session-config>

  <welcome-file-list>
    <welcome-file>base/main/login.jsp</welcome-file>
  </welcome-file-list>

  <!-- 根据返回状态码或异常类型指定显示页面 -->
  <error-page>
      <error-code>404</error-code>
      <location>/resource/error/noExistent.jsp</location>
  </error-page>
  <error-page>
