等到要在web.xml加入taglib
<taglib>
<taglib-uri>/WEB-INF/tiles.tld</taglib-uri>
<taglib-location>/WEB-INF/tiles.tld</taglib-location>
</taglib>
始終會報錯
後來把頭部改爲
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">
