我试图实现primefaces文件上传,但没有调用bean方法,顺便说一下我使用Spring框架和prettyfaces:Primefaces <P:文件上传不调用Bean方法
faces-config.xml中:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.2" xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

.xhtml代码:
<h:form enctype="multipart/form-data" prependId="false">
<p:fileUpload mode="simple" value="#{templateController.file}" />
<p:commandButton value="Upload" actionListener="#{templateController.upload}" ajax="false" />
</h:form>
豆方法:
public void upload() {
FacesMessage msg = new FacesMessage("Success! is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
我尝试添加转发给过滤器,因为我还使用漂亮的面孔,但仍然没有工作,谢谢。
好我解决了很多问题,我的解决方案是在web.xml文件中添加一个context-param(primefaces.UPLOADER)(检查this答案请),这个文件看起来是这样的,也可能是有帮助的设置项目阶段发展(在此文件中注释),这可以给你相关的调试过程中的一些附加信息:

尝试执行以下,
此方法添加到你的bean,
public void handleProfileFileUpload(FileUploadEvent event) {
if (event != null) {
try {
InputStream inputStream = event.getFile().getInputstream();
// Set inputstream to your object
} catch (IOException e) {
e.printStackTrace();
}
}
}
删除命令按钮并修改类似于这样的FileUpload配置,fileUploadListener最后经过处理上传
<p:fileUpload fileUploadListener="#{<your bean>.handleProfileFileUpload}"
mode="advanced" sizeLimit="2097152"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
已经尝试过,但仍然无法正常工作。 –
您可以在handleProfileFileUpload方法中的事件对象的调试中看到什么? – SAP
好吧不多说真的,无论是在网络浏览器控制台都没有任何的js错误 –
如果你正在使用Spring MVC,你的过滤器映射应该指向Spring DispatcherServlet而不是Faces Servet。
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Spring MVC Servlet</servlet-name>
</filter-mapping>
你的意思是Spring MVC? OP没有使用它。据我所知,使用JSF和MVC同时是一个不错的选择(如果有的话,请参阅http://stackoverflow.com/questions/18744910/using-jsf-as-view-technology-of-spring-mvc) – Kukeltje
我使用Spring MVC/Webflow和Primefaces和JPA,没有任何问题。我不相信这是一个不错的选择 当你说“OP不使用它”时,你是什么意思? –
你使用Spring MVC还是Spring Webflow?两种不同的技术,如果我阅读我仔细发布的链接。你可以使用Spring的Webflow与JSF,但并非Spring MVC框架(尽管你可以,如果我正确地读它运行它们并排)。所以,如果你真的这样做比这更多的,我会很感兴趣,如果有一些代码公开访问,看看它是如何实际使用,并可能纠正我发布的链接 – Kukeltje
托管bean的范围是什么? – SAP
它有会话范围 –
