WebService file upload Download (byte[] Implementation method)

Test environment: axis2-1.6.1, 6.0.20, jdk1.5

Note: This method is only applicable to scenes with files less than 10M (otherwise there will be memory overflow), upload and download large files should be another way.

1. Create a Java class to be published as WebService.

ImportJava.io.FileInputStream;ImportJava.io.FileOutputStream;Importjava.io.IOException; Public classBlobservice {/** File Upload service*/     Public BooleanUploadFile (String FileName,byte[] bytes) {FileOutputStream fos=NULL; Try{fos=NewFileOutputStream ("f:\\" +fileName); //writes the data in the byte array bytes to the file output stream in the FOSfos.write (bytes);        Fos.flush (); }Catch(Exception e) {e.printstacktrace (); return false; }finally{            Try{fos.close (); } Catch(IOException e) {e.printstacktrace (); }              }        return true; }    /** File Download service*/     Public byte[] DownloadFile () {String filepath= "F:\\head.jpg"; FileInputStream in=NULL; byteBytes[] =NULL; Try{ in=NewFileInputStream (filepath); Bytes=New byte[In.available ()]; //reads Bytes.length bytes of data from input stream in into a byte array bytesin.read (bytes); } Catch(Exception e) {e.printstacktrace (); }finally{                    Try{in.close (); } Catch(IOException e) {e.printstacktrace (); }        }        returnbytes; }}

2. Put the compiled class file of the above Java classes into the Axis2\web-inf\pojo directory.

3, write the client program.
