LinkAction.java:
package com.sicmsb.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.actions.DispatchAction;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForward;
public class LinkAction extends DispatchAction {
public ActionForward Search(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
return mapping.findForward("search");
}
}
我设法创建模板并在没有&#34;名称&#34;的情况下调用表单。在工作,然后我意识到我必须调用具有名称属性(CommentsUpdated
)的表单,以便我能够传递变量以从数据库中挖掘数据。不幸的是,它会抛出这样的错误:
javax.servlet.jsp.JspException: Cannot find bean: "CommentsUpdated" in any scope
。
我理解serachMyUser.jsp
中的名称属性导致此错误,但我仍然坚持这一部分,我试图在谷歌搜索示例,但我得到的只是在没有名称属性的情况下调用表单。
答案 0 :(得分:0)
<action path="/Link" parameter="method" type="com.sicmsb.action.LinkAction" name="CommentsUpdated">
<forward name="baseLayout" path="baseLayout"/>
<forward name="search" path="search"/>
<forward name="details" path="details"/>
<forward name="insert" path="insert"/>
最后我发现了问题,我在struts-config.xml中的活动中输入name="CommentsUpdated"
后就可以了!希望这对其他人也有帮助!
答案 1 :(得分:0)
如果您未在操作配置中设置db.user1.update({},
{$pull: {'transactions.2017.3': {_id: ObjectId("58c3154a19f82c0ddc53f0de")}}
});
属性,该属性应与name
名称相同,但在标记中使用了该名称
<form-bean>
当然你有例外
无法在任何范围内找到bean:“CommentsUpdated”
如果配置了表单bean和操作名称,Struts将实例化一个表单bean并将其传递给操作。如果你想自己实例化它,那么在JSP中访问它之前你应该把它放到任何范围内。
