我的实现：
<h:form enctype="multipart/form-data">
<p:fileUpload id="fileUpload"
fileUploadListener="#{fileUploadController.handleFileUpload}"
mode="advanced" update="messages" sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
<p:growl id="messages" showDetail="true" />
我在我的 web.xml 文件中配置了我的过滤器：
<!-- ############################################# -->
<!-- # File upload # -->
<!-- ############################################# -->
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>
org.primefaces.webapp.filter.FileUploadFilter
</filter-class>
<init-param>
<param-name>thresholdSize</param-name>
<param-value>6400</param-value>
</init-param>
<init-param>
<param-name>uploadDirectory</param-name>
<param-value>/resources/uploads</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
在我的 pom.xml 中：
- 公共文件上传
- commons-io
我的文件上传控制器看起来像这样：
@Component
@Scope("session")
public class FileUploadController {
private int size = 1024;
/**
* log4j
*/
private static Logger log = LogManager.getLogger(FileUploadController.class);
public void handleFileUpload(FileUploadEvent event) {
log.info("Method handleFileUpload invoked");
FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
try {
File targetFolder = new File("/resources/uploads/images");
InputStream inputStream = event.getFile().getInputstream();
OutputStream out = new FileOutputStream(new File(targetFolder,
event.getFile().getFileName()));
int read = 0;
byte[] bytes = new byte[size];
log.info("read file stream");
while ((read = inputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
inputStream.close();
out.flush();
out.close();
} catch (IOException e) {
log.error(e);
e.printStackTrace();
}
}
我的问题是，我没有从控制器获得日志消息来上传我的文件？
真的很感谢你的回答！！！
顺便说一句，我的 PF 版本是 3.5
