Question

我想发送一个表单来更新我的用户，该表单包含一个modelAttribute和一个要上传的图片。

如果我使用enctype =＆＃34; multipart / form-data＆＃34;图像已上传，但modelAttribute中的所有字段均为空。

如果我删除了enctype =＆＃34; multipart / form-data＆＃34;我的modelAttribute已正确填充，但图片未上传...

你有解决方案吗？

我的代码如下：

jsp：

<portlet:actionURL name="submitMyInfosForm" var="submitMyInfosFormUrl">
     <portlet:param name="submitMyInfosForm" value="submitMyInfosForm"/>
</portlet:actionURL>

<form:form class="fm" modelAttribute="myInfosForm" action='${actionFormUrl}' enctype="multipart/form-data" method="post" id='myInfosForm'>      
                    <div class="fm_c">      
                        <label class="fm_c_n">
                            <p><spring:message code="portlet.moncompte.infos.form.firstname"/></p>
                            <input type="text" name="firstName" value="${myInfosForm.firstName}" <c:if test="${not isUpdateInfos}"> class="disabled" disabled</c:if> />
                            <div id="error_infos_firstName" class="error"></div>
                        </label>

                        <label class="fm_c_n">

控制器：

 @ActionMapping(params = "javax.portlet.action=submitMyInfosForm")
    public void updateMyInfos(@ModelAttribute MyInfosForm infosForm, ActionRequest request, ActionResponse response,
            Model model) {

modelAttribute：

public class MyInfosForm {

    private String firstName;

    private String lastName;

    private String emailAddress;

    private String phone;

    private String street1;

    private String street2;

    private String zip;

    private String city;

    private MultipartFile portrait;
...
}

使用UploadPortletRequest

时，您需要使用ActionRequest代替enctype="multipart/form-data"

我不熟悉Spring Framework，但您可以使用UploadPortletRequest获取ActionRequest，

UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(actionRequest);

您可以获取内容并使用它，

File file = uploadRequest.getFile("fileName");
String someData = ParamUtil.getString(uploadRequest, "someData");

使用ModelAttribute Liferay上传图片
