springMVC 错误页面配置

在Spring MVC应用程序中，404 error code 被合适的配置。web.xml文件中配置如下所示： 

<!-- spring mvc start -->
  <servlet>
    <servlet-name>SpringMVC_FrontControl</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/xmlConfig/webConfig/*.xml,</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>SpringMVC_FrontControl</servlet-name>
    <url-pattern>*.html</url-pattern>
  </servlet-mapping>
  <!-- spring mvc ends -->

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
  <error-page>
        <error-code>404</error-code>
        <location>/WEB-INF/webPage/test/404.jsp</location>
    </error-page>

当用户访问任意不存在或者报错时的资源时，它就会转向404.jsp页面。
