spring hibernate javax.el.PropertyNotFoundException

我的项目在将一个属性

endDate

和它的

getter&setter

添加到实体

project

后出现错误：

javax.el.PropertyNotFoundException: Property 'endDate' not found on type com.mvc.project.bean.Project

我的项目bean如下所示：

在jsp中，endDate有以下标记。我还提供了开始日期标签，以供参考：

<td>Start Date</td>
                <td><form:input type="date" class="disable1" name="startdate" id="startdate" path="startDate" required="true" /></td>

                <td>End Date</td>
                <td><form:input type="date" class="disable1" name="enddate" id="enddate" path="endDate"/></td>

开始日期
结束日期

这是一个ajax调用，因此当我在预加载的jsp中按下一个链接时，将调用/tab2 url，这将在我的控制器上进一步调用以下内容：

@RequestMapping("/tab2")
    public String redirectjsp(Map<String,Object> map){
        Project project = new Project();
        map.put("project", project);
        map.put("projectList", projectService.getAllproject());

        return "tab2";

    }

@RequestMapping（“/tab2”）
公共字符串重定向JSP（映射）{
项目=新项目（）；
地图放置（“项目”，项目）；
put（“projectList”，projectService.getAllproject（））；
返回“tab2”；
}

在我补充之前，一切都很顺利

jsp中的endDate标记

使用“项目”bean的getter和setter在“项目”bean中创建了一个属性，并包含在bean的构造函数中

在“project”表中的我的数据库中添加了一个字段endDate

真奇怪！！我从jsp、project类中删除了我的endDate，代码再次启动。然后我从Project类中删除了我的startDate，代码仍然运行良好，就好像它没有从Project类中获取startDate一样

---

我删除了整个projectbean类，代码仍在运行，我不知道它引用的是哪个projectbean类，甚至不知道它是否引用

属性enddate在jsp页面中定义为表达式语言时不正确

如果要使用类之间的关系，则必须定义表示关联的属性

没有关系：

${x.enddate}

${x.class.enddate}

关于：

${x.enddate}

${x.class.enddate}

---

为了确保jsp页面可以访问bean字段，可以使用IDE的generate Getter和Setter方法。我认为它比手动键入getter和setter要准确得多

source>generate setters and getters select field to generate getters and setters.

您可以通过

${project.endDate}

用EL调用endDate对象，我可以在您的代码中看到您有一个项目列表？用foreach迭代它

导入标记库

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

迭代列表

<c:foreach items="projectlist" var="proj">

<c:out value="${proj.endDate}"/>

</c:foreach>

谢谢大家的宝贵意见。我终于找到了解决方案并发布了帖子，以防其他人也遇到同样的问题

实际上，我项目的元数据已损坏。我关闭了eclipse，进入工作区并删除了.metadata文件夹。然后我通过导入>常规>工作区中的现有项目再次导入该项目。现在一切都按预期进行

---

此外，我使用瓷砖渲染我的输出。我正在更改“tab2.jsp”并期待更改，但实际上，当我查看tiles配置器时，它被配置为返回tab2\u update.jsp，而不是返回tab2\u update.jsp

你能添加你的控制器和JSP吗？你确定你的

Project

表有一列

endDate

？还有，你是从哪里得到这个错误的？请发布完整的上下文。您是否尝试清理、重建和重新部署代码？

具有不同的属性：类的cssClass，名称和id的路径。因此，请尝试删除名称和id。这是尝试过的文档，但错误仍然存在。谢谢ker p pag，您能发布您的jsp代码吗？在这里您可以调用endDate.document.getElementById（“releasedate”）.value=“”；document.getElementById（“startdate”）.value=“”；document.getElementById（“enddate”）.value=“”；document.getmentById（“projstatus”）.value=“”；在你的帖子中，项目不是projI，你用“proj”变量引用了项目projectList'包含项目列表。
