类 DefaultHttpDataFactory

java.lang.Object

io.netty.handler.codec.http.multipart.DefaultHttpDataFactory

所有已实现的接口:

HttpDataFactory

public class DefaultHttpDataFactory
extends java.lang.Object
implements HttpDataFactory

Default factory giving Attribute and FileUpload according to constructor.

According to the constructor, Attribute and FileUpload can be:

• MemoryAttribute, DiskAttribute or MixedAttribute
• MemoryFileUpload, DiskFileUpload or MixedFileUpload

A good example of releasing HttpData once all work is done is as follow:

   for (InterfaceHttpData httpData: decoder.getBodyHttpDatas()) {
     httpData.release();
     factory.removeHttpDataFromClean(request, httpData);
   }
   factory.cleanAllHttpData();
   decoder.destroy();

方法详细资料

setBaseDir

public void setBaseDir(java.lang.String baseDir)

Override global DiskAttribute.baseDirectory and DiskFileUpload.baseDirectory values.

参数:
