web.xml根结点下增加
1 <error-page> 2 <error-code>400</error-code> 3 <location>/WEB-INF/jsp/error/400.jsp</location> 4 </error-page> 5 <error-page> 6 <error-code>404</error-code> 7 <location>/WEB-INF/jsp/error/404.jsp</location> 8 </error-page> 9 <error-page> 10 <error-code>406</error-code> 11 <location>/WEB-INF/jsp/error/406.jsp</location> 12 </error-page> 13 14 <error-page> 15 <exception-type>java.lang.Throwable</exception-type> 16 <location>/WEB-INF/jsp/error/500.jsp</location> 17 </error-page>
编写相应的错误文件（以500.jsp错误为例）
