關(guān)于x:inputFileUpload

inputFileUpload是myfaces里的一個組件，用來上傳文件的。本人這幾天一直試著使用這個組件，結(jié)果均以失敗告終。上網(wǎng)搜查資料，結(jié)果是千篇一律，更加郁悶。

幾經(jīng)嘗試，終于發(fā)現(xiàn)為什么這組件失效。

第一點：在里需加上enctype="multipart/form-data"

第二點：需在web.xml文件中加上以下東東：

extensionsFilter
org.apache.myfaces.component.html.util.ExtensionsFilter

uploadMaxFileSize
100m



uploadThresholdSize
100k





extensionsFilter
*.faces

如果你像我一樣為這個組件困擾的話，按照上面的試試，應(yīng)該就可以成功了。

附上本人的測試樣例，詳細請進入收看。
