WebService File Upload Download

Use DataHandler to implement WebService file upload and download

Service-Side code:

 PackageCom.hello.weChat.controller;ImportJavax.activation.DataHandler;ImportJavax.activation.FileDataSource;ImportJava.io.File;ImportJava.io.FileOutputStream;Importjava.io.IOException;ImportJava.io.InputStream;/*** Created by Winkey on 15-2-10.*/ Public classFilecontroller {/** File Upload service*/     Publicstring Upload (DataHandler handler, string fileName) {string FullPath= "F:\\test\\testupload\\" +FileName; File File=NewFile (FullPath); intFlag = 0; if(Handler = =NULL)            return"Failure"; if(FileName = =NULL)            return"Failure"; InputStream input=NULL; FileOutputStream Fos=NULL; Try{input=Handler.getinputstream (); FOS=Newfileoutputstream (file); byte[] buffer =New byte[4096];  while(flag = input.read (buffer))! =-1) {fos.write (buffer,0, flag); }        } Catch(IOException e) {e.printstacktrace (); return"Failure"; } finally {            Try {                if(Input! =NULL) {input.close (); }                if(Fos! =NULL) {fos.close (); }            } Catch(IOException e) {e.printstacktrace (); }        }        return"Success"; }    /** File Download service*/     PublicDataHandler downloadFile () {String filepath= "F:\\test\\head.jpg"; DataHandler DataHandler=NewDataHandler (NewFiledatasource (filepath)); System.out.println ("-------------------------Download"); returnDataHandler; }}

Server-side WSDD file configuration

Only configure typemapping when downloading, need to configure both operation and typemaping when uploading
