实际上在我的 spring 应用程序中有 User.jsp 并使用这个 Jsp 我显示详细信息。

在我的 UserProfileForm bean 中，我正在写

private List<ProfessionalForm> professionalDetails = new ArrayList<ProfessionalForm>();

而ProfessionalForm 有另一种形式的细节。

在我的控制器类中，我正在写..

 @RequestMapping(value = "user", method = RequestMethod.GET)
    public String user(Model model) throws Exception {
        UserProfileForm form = (UserProfileForm)FormType.USER_PROFILE.getNewInstance();

        model.addAttribute("USER_PROFILE", form);
        return "profile/user";
    }

还有我的 user.jsp 页面代码..

<form:form action="" modelAttribute="USER_PROFILE">
   <div class="answer">
    <c:forEach items="${USER_PROFILE.professionalDetails}" var="professionalForm">
        <jsp:include page="user/professional.jsp">
           <jsp:param value="${professionalForm}" name="PROFESSIONAL" />
        </jsp:include>
    </c:forEach>
   </div>
</form:form>

这是我的专业.jsp ..

<form:form action="profile/proffessional" modelAttribute="PROFESSIONAL">
<p>
  <label class="control_label">Postion:</label>
    <div class="controls">
        <form:input class="text_midem" path="positionName" />
    </div>
</p>
</form>

但是我的服务器控制台出现了以下异常..

    SEVERE: Servlet.service() for servlet [spring] in context with path [/EClass] threw exception [An exception occurred processing JSP page /WEB-INF/pages/profile/user.jsp at line 40

37:                         <div class="answer">
38:                             <c:forEach items="${USER_PROFILE.professionalDetails}"
39:                                 var="professionalForm">
40:                                 <jsp:include page="user/professional.jsp">
41:                                     <jsp:param value="${professionalForm}" name="PROFESSIONAL" />
42:                                 </jsp:include>
43:                             </c:forEach>


Stacktrace:] with root cause
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'PROFESSIONAL' available as request attribute
    at org.springframework.web.servlet.support.BindStatus.<init>(BindStatus.java:141)

为什么这条消息是他们在 User.jsp 页面或 Professional.jsp 中需要的任何循环。

请帮我..

编辑：

而不是<jsp:include>我们使用...

<%@include file="user/professional.jsp"%>

听说还有错误来...

    SEVERE: Servlet.service() for servlet [spring] in context with path [/EClass] threw exception [An exception occurred processing JSP page /WEB-INF/pages/profile/user/professional.jsp at line 16

13:                                 <p>
14:                                     <label class="control_label">Postion:</label>
15:                                 <div class="controls">
16:                                   <form:input class="text_midem" path="positionName" />
17:                                 </div>
18:                                 </p>
19:                                 <p>

使用 <%@include%> 代替 jsp:include

<%@include file="user/professional.jsp"%>

......
<jsp:include page="user/professional.jsp">
           <jsp:param value="${professionalForm}" name="PROFESSIONAL" />
        </jsp:include>
.......

上面的代码将名为 PROFESSIONAL 的请求参数发送到专业.jsp 页面，而不是请求属性。虽然下面的代码寻找请求属性

....
<form:form action="profile/proffessional" modelAttribute="PROFESSIONAL">
....

因此，您可能需要将该值设置为请求属性。

试试下面的代码

.......

<form:form action="" modelAttribute="USER_PROFILE">
   <div class="answer">
    <c:forEach items="${USER_PROFILE.professionalDetails}" var="professionalForm">
        <c:set var="PROFESSIONAL" scope="request" value="${professionalForm}">
        <jsp:include page="user/professional.jsp">           
        </jsp:include>
    </c:forEach>
   </div>
</form:form>
