<welcome-file-list>
  <welcome-file>/WEB-INF/views/login.jsp</welcome-file>
  </welcome-file-list>

  <!-- 1.替换403页面 start -->
  <error-page>
    <error-code>403</error-code>
    <location>/WEB-INF/views/page_403.jsp</location>
  </error-page>
  <!-- end -->
  <!-- 2.替换404页面 start -->
  <error-page>
    <error-code>404</error-code>
    <location>/WEB-INF/views/page_404.jsp</location>
  </error-page>
  <!-- end -->
  <!-- 3.替换500页面 start -->
  <error-page>
    <error-code>500</error-code>
    <location>/WEB-INF/views/page_500.jsp</location>
  </error-page>
