Question

首先，我使用的技术Primefaces 6.1，PrettyFaces 3.3.3和Wildfly 11。我只想用Primefaces将文件上传到我的数据库 <p:fileUpload>组件。这是我使用过的代码片段。

<h:form>
    <p:fileUpload fileUploadListener="#{imageopbean.uploadImage}"  mode="advanced" auto="true" style="display:none;" oncomplete="uppicture()" styleClass="imageUploadButton" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" >
          <f:attribute name="uniqueid" value="#{profileBean.theUser.userId}"/>
     </p:fileUpload>
</h:form>

在我使用PrettyFaces库之前它正在工作。现在，它不会调用fileUploadListener。我已阅读this问题和其他一些解决方案。但我不能让他们工作。我究竟做错了什么？这是我的代码的其他部分。感谢。

我在web.xml中尝试了大多数过滤器组合，但没有任何效果。我找到了这个，

我删除了我在web.xml和pom.xml中插入的所有内容。以下是解决方案：

1-将enctype="multipart/form-data"添加到您的<h:fom>代码

2-根据您的JSF页面编辑脚本

<script type="text/javascript">
     $(document).ready(function() {
         $("form[enctype='multipart/form-data']").attr("action","#{request.contextPath}/test/fileupload.xhtml");
    });
</script>
