这是我的方法

System.out.println(extContext.getRealPath("/WebContent/resources/images/" + event.getFile().getFileName()));
try{
FileOutputStream fileOutputStream = new FileOutputStream(result);
byte[] buffer = new byte[BUFFER_SIZE];
int bulk;
InputStream inputStream = event.getFile().getInputstream();
while(true){
bulk = inputStream.read(buffer);
if(bulk < 0){
break;
}
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
}
fileOutputStream.close();
inputStream.close();
FacesMessage msg = new FacesMessage("File Description", "file name: " + event.getFile().getFileName() +

event.getFile().getContentType() + "<br/><br/>The file was uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
} catch(IOException e){
e.printStackTrace();
FacesMessage error = new FacesMessage(FacesMessage.SEVERITY_ERROR, "The files were not uploaded!", "");
FacesContext.getCurrentInstance().addMessage(null, error);
}
