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"%>

]]>struts:logic标签http://www.blogjava.net/fangts/archive/2007/12/18/168419.html方涛升方涛升Tue, 18 Dec 2007 02:52:00 GMThttp://www.blogjava.net/fangts/archive/2007/12/18/168419.htmlhttp://www.blogjava.net/fangts/comments/168419.htmlhttp://www.blogjava.net/fangts/archive/2007/12/18/168419.html#Feedback0http://www.blogjava.net/fangts/comments/commentRss/168419.htmlhttp://www.blogjava.net/fangts/services/trackbacks/168419.html   1. logic:equal
          该标签为等于比较符。
          eg1. 比较用户的状态属性是否1，若为1，输出"启用";
                 <logic:equal   name="user"   property="state"   value="1">
                     启用
                 </logic:equal>
         eg2. 如果上例中的value值是动态获得的，例如需要通过bean:write输出，因struts不支持标签嵌套，可采用EL来解决该问题。
                <logic:equal   name="charge"   property="num"   value="${business.num}">    IT资讯之家 www.it55.com
                    ......
                </logic:equal>
2. logic:present
           此标签用于判断request对象传递参数是否存在。
           eg1. user对象和它的name属性在request中都存在时，输出相应字符串：
              <logic:present name="user" property="name">
                  user对象和该对象的name属性都存在
            </logic:present>  www.it55.com在线教程
          eg2. 若有一个名字为“user”的JavaBean，输出对应字符串：
             <logic:present name="user" >
                  有一个名字为“user”的JavaBean。
            </logic:present>
          eg3. 
            <logic:present header="user-agent">
                  we got a user-agent header.
            </logic:present>
3. logic:iterator
            用于显示列表为collection的值（List ,ArrayList,HashMap等）。
            eg1. 逐一输出用户列表(userlList)中用户的姓名：
               <logic:iterate  id="user" name="userList">
                  <bean:write name="user" property="name"/><br>

IT资讯之家 www.it55.com


               </logic:iterate>
            eg2. 从用户列表中输出从1开始的两个用户的姓名
               <logic:iterate  id="user" name="userList" indexId="index"  offset="1" length="2">
                  <bean:write name="index"/>.<bean:write name="user" property="name"/><br>
               </logic:iterate>
            eg3. logic:iterator标签的嵌套举例
                <logic:iterate id="user" indexId="index" name="userList">
                       <bean:write name="index"/>. <bean:write name="user" property="name"/><br>

                       <logic:iterate id="address" name="user" property="addressList" length="3" offset="1">
                           <bean:write name="address"/><br>
                       </logic:iterate>
               </logic:iterate> 免费
