在我在Apache Tomcat 6上运行的应用程序中,我使用PrimeFaces 3.0.M3中的fileUpload。但它无法正常工作。当我上传文件时,它出现在上传目录中,但事件未被触发。有人可以帮帮我吗?
我的观看代码:
<h:form prependId="false" id="uploadForm" enctype="multipart/form-data">
<p:fileUpload id="uploadControl" fileUploadListener="#{fileUploadBean.uploadHandler}" mode="advanced" />
</h:form>
FileUploadBean类源:
@ManagedBean
@RequestScoped
public class FileUploadBean implements Serializable {
private static final Logger logger = Logger.getLogger(FileUploadBean.class);
private UploadedFile file;
public void uploadHandler(FileUploadEvent event) throws AbortProcessingException {
logger.debug("uploadHandler(FileUploadEvent event)");
logger.debug("Uploaded file: " + event.getFile().getFileName());
}
public UploadedFile getFile() {
return file;
}
public void setFile(UploadedFile file) {
this.file = file;
}
}
我的web.xml:

答案 0 :(得分:3)
我认为您的问题出在web.xml
配置中,您为文件上传过滤器声明了两个不同的过滤器映射,其中一个不正确:
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
相反,你需要这个:
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
您只想将文件上传过滤器映射到Faces Servlet。
