1、web.xml文件里加上以下配置
<jsp-config>
    <taglib>
      <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
      <taglib-location>/WEB-INF/tld/c.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>
      <taglib-location>/WEB-INF/tld/fmt.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>http://java.sun.com/jsp/jstl/sql</taglib-uri>
      <taglib-location>/WEB-INF/tld/sql.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>http://java.sun.com/jsp/jstl/xml</taglib-uri>
      <taglib-location>/WEB-INF/tld/x.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>/tags/struts-bean</taglib-uri>
      <taglib-location>/WEB-INF/tld/struts-bean.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>/tags/struts-html</taglib-uri>
      <taglib-location>/WEB-INF/tld/struts-html.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>/tags/struts-logic</taglib-uri>
      <taglib-location>/WEB-INF/tld/struts-logic.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>/tags/struts-tiles</taglib-uri>
      <taglib-location>/WEB-INF/tld/struts-tiles.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>/tags/struts-nested</taglib-uri>
      <taglib-location>/WEB-INF/tld/struts-nested.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>http://ajaxtags.org/tags/ajax</taglib-uri>
      <taglib-location>/WEB-INF/tld/ajaxtags.tld</taglib-location>
    </taglib>
     <taglib>
      <taglib-uri>/tags/struts-template</taglib-uri>
      <taglib-location>/WEB-INF/tld/struts-template.tld</taglib-location>
    </taglib>
2、在WEB/INF下新建tld文件夹，将要用到的标签库都导入到文件夹内
3、新建include/tagtld.jsp
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
4、在所要用到的jsp中导入<%@include file="include/tagtld.jsp"%>
