struts freemarker map 问题，在线等

Question

在action 有一个map，Map pageMap = new HashMap()； 和set get方法，
数据是这样的，里面 有可能有多了。比如 还有AAAAA3=对应的对象
AAAAA2{AAAAA1=com.dxyt.ybjg.action.SelectIllegal@16f70a4, AAAAA2=com.dxyt.ybjg.action.SelectIllegal@14c5b37}com.dxyt.ybjg.action.SelectIllegal@16f70a4是这个对象，里面包含下属性。我想在freeer中取的 对象的属性我现在是这么写的： // students是map 的key
 <#list pageMap?keys as students> 
 // 通过pageMap[students] 可以取出key 所对应的对象
 <#assign stu = pageMap[students]>
     // 给对象as一个变量，也就是这个地方出的错 如下
     <#list stu as student> 
${student.illegalNo1} 
${student.illegalTime1} 
     </#list> 
 </#list> 
错误代码

Answer 1

如果用的是struts2：在freeer中引用struts2标签对map进行处理即可。

Answer 2

用的是struts2 ，具体 该怎么写 ，谢谢

Answer 3

不要assign 试试<#list pageMap?keys as students> 
    // 给对象as一个变量，也就是这个地方出的错 如下 
    <#list pageMap[students] as student> 
${student.illegalNo1} 
${student.illegalTime1} 
    </#list> 
</#list> 

Answer 4

1.将struts2标签库tld放在指定目录下。「/WEB-INF/struts-tags.tld」。
2.web.xml配置JspSupportServlet：
<servlet>
<servlet-name>JspSupportServlet</servlet-name>
<servlet-class>
    org.apache.struts2.views.JspSupportServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
3.模板使用<#assign s=JspTaglibs["/WEB-INF/struts-tags.tld"] />引用标签库。
4.模板中标签写法[<@s.标签名 />]。例：<@s.text name="key" />
5.action配置result type=freeer

Answer 5

把struts-tags.tld放进去后
<tlib-version>2.2.3</tlib-version>
提示错误multiple annotations found at this lin3: 
-cvc-type.3.1.3:the value '2.2.3' of element 'tlib-version' is not valid.
-cvc-datatype-valid.1.2.1:'2.2.3' is not a valid value for 'decimal'

Answer 6

不可能啊。我的项目运行正常啊。struts-tags.tld怎么来的。
放在什么位置。

Answer 7

解压struts2-core-2.1.6.jar 里面的
放在D:\workspace\yibinTraffic\WebContent\WEB-INF\struts-tags.tld

Answer 8

应该没有问题啊。你项目用的也是struts2.1.6

Answer 9

恩，是吖。 方便留个QQ msn 啥的吗

Answer 10

如果可以把项目压缩发给我看看[email protected]

Answer 11

 <#assign stu = pageMap[students]>
改成 <#assign stu = pageMap.get(students)>
