Spring jPetStore err:org.apache.jasper.JasperException: WEB-INFjspstrutsIncludeTop.jsp(23,0) According to TLD or attribute d

    Sping Demo JpetStore 当web.xml配置和struts整合时,运行jsp页面会出现如下错误:

    org.apache.jasper.JasperException: /WEB-INF/jsp/struts/IncludeTop.jsp(23,0) According to TLD or attribute directive in tag file, attribute test does not accept any expressions.

    原因是jstl 的包tld文建已经打好到standard包中,这个standard.jar是1.0版本的核心库tld描述,而jsp页面使用的都是jstl1.1的语法,所以必须把1.1的tld拷贝到WEB-INF/下,并在web.xmll中重新定义taglib,为了尽量不修改jsp文件对jstl的引用,按照jsp引用taglib的uri来修改web.xml中jstl的taglib的uri。如下:

    <jsp-config>  <taglib>      <taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri>      <taglib-location>/WEB-INF/struts-bean.tld</taglib-location>    </taglib>    <taglib>      <taglib-uri>/WEB-INF/struts-html.tld</taglib-uri>      <taglib-location>/WEB-INF/struts-html.tld</taglib-location>    </taglib>    <taglib>      <taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri>      <taglib-location>/WEB-INF/struts-logic.tld</taglib-location>    </taglib>    <taglib>      <taglib-uri>/WEB-INF/struts-tiles.tld</taglib-uri>      <taglib-location>/WEB-INF/struts-tiles.tld</taglib-location>    </taglib>    <taglib>      <taglib-uri>/WEB-INF/struts-nested.tld</taglib-uri>      <taglib-location>/WEB-INF/struts-nested.tld</taglib-location>    </taglib>     <taglib>  <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>  <taglib-location>/WEB-INF/c.tld</taglib-location> </taglib> <taglib>  <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>  <taglib-location>/WEB-INF/fmt.tld</taglib-location> </taglib> <taglib>  <taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>  <taglib-location>/WEB-INF/sql.tld</taglib-location> </taglib> <taglib>  <taglib-uri>http://java.sun.com/jstl/x</taglib-uri>  <taglib-location>/WEB-INF/x.tld</taglib-location> </taglib>    </jsp-config>

    jsp页面使用

    <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %><%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>

    这样就不报错了。
