Question

Struts2 的select，动态绑定数据库，在jsp页面中action不执行...

进入jsp页面时报错 The requested list key 'list' could not be resolved as a collection/array/map/enumeration/iterator type.

这个是jsp页面代码
<struts:form action="GetXs" >
<struts:select name="xy" headerKey="-1" headerValue="请选择学院"
list="list" required="true"></struts:select>
</struts:form>
action 代码
public String execute() throws Exception
{
list = userModualService.xsBind();
ServletActionContext.getRequest().setAttribute("lits", list);
return SUCCESS;
}

直接在浏览器中执行action是可以的，所以怀疑是jsp页面没有成功执行action

Answer 1

<struts:select name="xy" headerKey="-1" headerValue="请选择学院"
list=${list} required="true"></struts:select>
</struts:form>

Answer 2

list={list}你这个是个集合吧！

Answer 3

lisi=${list}
