【问题描述】:
首先,我使用Primefaces 6.1、PrettyFaces 3.3.3 和Wildfly 11 的技术。我只是想用 Primefaces 将文件上传到我的数据库
<p:fileUpload> 组件。这是我用过的代码sn-p。
<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 库之前它就可以工作。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。谢谢。

【问题讨论】:
-
如果您“自动”添加了 PrettyFaces 过滤器(通过添加 jar),也许您需要添加一些显式排序(您可以在您在问题中链接到的帖子,在“疑难解答”中排名第一)
-
我在副本中的 #1 中添加了一些额外的注释。对你有帮助吗?
-
我正在使用带注释的网络过滤器,所以您的意思是网络过滤器可能会消耗上传请求?
-
-
我更新我的 web.xml 仍然无法正常工作。您可以查看问题@Kukeltje
