Java bean name'；的BindingResult或普通目标对象；configId'；可用作请求属性Jasper异常

我正在开发spring CRUD应用程序。在我的列表屏幕中，当点击编辑按钮时，我有一个编辑按钮，它必须重定向到另一个有表单输入字段的页面。我要编辑的内容将加载到那里

这里是我正在使用的jsp

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

这是我的update.jsp代码

 <form:form action="updateContact.do" commandname="FeedUpdate" method="post"></form:form>
                    <div class="small-3 columns">
                     <label for="right-label" class="right inline">Config Id</label>
                     </div>

                    <div class="small-9 columns">
                    <form:input path="configId" readonly="true"></form:input>
                    </div>

                    <div class="row">
                    <div class="small-3 columns">
                    <label for="right-label" class="right inline">Feed Id</label>
                    </div>

                    <div id="val" class="small-9 columns">
                    <form:input path="feedId" readonly="true"></form:input>
                    </div>

检查“

configId

”是否作为属性（以及有效的getter和setter）存在于您的

FeedForm.java

 <form:form action="updateContact.do" commandname="FeedUpdate" method="post"></form:form>
                    <div class="small-3 columns">
                     <label for="right-label" class="right inline">Config Id</label>
                     </div>

                    <div class="small-9 columns">
                    <form:input path="configId" readonly="true"></form:input>
                    </div>

                    <div class="row">
                    <div class="small-3 columns">
                    <label for="right-label" class="right inline">Feed Id</label>
                    </div>

                    <div id="val" class="small-9 columns">
                    <form:input path="feedId" readonly="true"></form:input>
                    </div>

@RequestMapping(value="/updateFeed", method=RequestMethod.GET)
public ModelAndView edit(@RequestParam("key")Integer id)
{
    FeedForm feedForm = new FeedForm();

    ModelAndView mav = new ModelAndView("FeedUpdate");

    FeedFormDAO feedFormDAO = new FeedFormDAO();
    feedForm = feedFormDAO.selectFeed(String.valueOf(id));

    mav.addObject("FeedUpdate", feedForm);
    return mav;
}
