openadaptor1--transferring large files based on WebService

<span style= "font-family:arial, Helvetica, Sans-serif; Background-color:rgb (255,255,255) ">openadaptor support Xfire and CXF development WebService, so the development of CXF WebService, based on MyEclipse development is relatively easy.

1. The first is a myfile class that encapsulates the server-side file path, the client file path, and the byte array to be transferred.

package Com.cattsoft.baseplatform.webservice.fileltransfer;public class MyFile {private String Clientfile;private string serverfile;//Statistics total uploads downloaded bytes Private long position;//each uploaded or downloaded byte array private byte[] bytes;public String getclientfile () { return clientfile;} public void Setclientfile (String clientfile) {this.clientfile = Clientfile;} Public String Getserverfile () {return serverfile;} public void Setserverfile (String serverfile) {this.serverfile = Serverfile;} Public long getPosition () {return position;} public void SetPosition (long position) {this.position = position;} Public byte[] GetBytes () {return bytes;} public void setbytes (byte[] bytes) {this.bytes = bytes;}} 

2. Web service interface for file transfer

Package Com.cattsoft.baseplatform.webservice.fileltransfer;import Javax.jws.webmethod;import Javax.jws.WebService ; @WebServicepublic interface Filetransferservice {@WebMethodvoid uploadfile (string address, string Clientfile, String Serverfile) throws filetransferexception; @WebMethodvoid UploadFile1 (MyFile MyFile, String address) throws Filetransferexception, @WebMethodvoid uploadFile2 (MyFile MyFile) throws filetransferexception; @WebMethodvoid DownloadFile (string address, String clientfile, String serverfile) throws filetransferexception; @WebMethodvoid DownloadFile1 (MyFile MyFile, String address) throws Filetransferexception; @WebMethodMyFile DownloadFile2 (MyFile MyFile) throws filetransferexception;}

3. Web Service Interface Implementation classes for file transfers, mainly for some flow operations

Package Com.cattsoft.baseplatform.webservice.fileltransfer;import Java.io.file;import Java.io.FileInputStream; Import Java.io.ioexception;import java.io.inputstream;import Java.io.outputstream;import Java.util.Arrays;import Javax.jws.webservice;import Org.apache.commons.io.fileutils;import Org.apache.commons.io.ioutils;import Org.apache.cxf.jaxws.JaxWsProxyFactoryBean; @WebService (endpointinterface = " Com.cattsoft.baseplatform.webservice.fileltransfer.FileTransferService ", ServiceName =" Filetransferservice ") public class Filetransferserviceimpl {//byte[] Transfer of files, each transfer of 1024*1024, after transfer myfile.setposition record total bytes transferred public void UploadFile (string address, String clientfile, String serverfile) throws Filetransferexception {InputStream is = null;try { MyFile MyFile = new MyFile (); is = new FileInputStream (clientfile); byte[] bytes = new byte[1024 * 1024];while (TRUE) {int S ize = Is.read (bytes);//The read data from the input stream is stored in the buffered array bytes, returning the number of bytes read until the end of the file is detected. Reads at most equivalent to read (bytes,//0, Bytes.length) if (size <= 0) {//returns-1 means end of file BReak;} byte[] fixedbytes = arrays.copyofrange (bytes, 0, size);//Copy bytes array to fixedbytes array, from 0 to Sizemyfile.setclientfile ( Clientfile); Myfile.setserverfile (serverfile); myfile.setbytes (fixedbytes); UploadFile1 (myFile, address); Myfile.setposition (myfile.getposition () + fixedbytes.length);//number of bytes transferred}} catch (IOException e) {throw new Filetransferexception (E.getmessage (), E); Finally {ioutils.closequietly (IS);}} public void UploadFile1 (MyFile MyFile, String address) throws Filetransferexception {Jaxwsproxyfactorybean Factorybean = New Jaxwsproxyfactorybean (); factorybean.setaddress (address); Factorybean.setserviceclass ( Filetransferservice.class); Object obj = Factorybean.create (); Filetransferservice service = (filetransferservice) obj;service.uploadfile2 (myFile);}  public void UploadFile2 (MyFile MyFile) throws filetransferexception {OutputStream os = null;try {if (Myfile.getposition () ! = 0) {//Use Apache Commons-io FileUtils Tool class//open stream, if there is no creation file and its directory structure, the second parameter indicates whether the file stream is an append mode OS = Fileutils.openoutputstream (new File (Myfile.getserverfile ()), true);} else {OS = Fileutils.openoutputstream (New File (Myfile.getserverfile ()), false);} Os.write (Myfile.getbytes ());} catch (IOException e) {throw new Filetransferexception (E.getmessage (), e);} finally {ioutils.closequietly (OS)}} public void DownloadFile (string address, String clientfile, String serverfile) throws Filetransferexception {MyFile MyFile = new MyFile (); Myfile.setserverfile (serverfile); Long position = 0;while (true) {myfile.setposition (position); MyFile = DownloadFile1 (myFile, address), if (Myfile.getbytes (). length <= 0) {break;} OutputStream OS = null;try {if (position! = 0) {OS = Fileutils.openoutputstream (new File (Clientfile), true);} else {os = F Ileutils.openoutputstream (New File (Clientfile), false);} Os.write (Myfile.getbytes ());} catch (IOException e) {throw new Filetransferexception (E.getmessage (), e);} finally {ioutils.closequietly (OS);} Position + = Myfile.getbytes (). length;}} Public MyFile DownloadFile1 (MyFile MyFile, String address) throws filetransferexception {Jaxwsproxyfactorybean Factorybean = new Jaxwsproxyfactorybean (); Factorybean.setaddress ( address); Factorybean.setserviceclass (filetransferservice.class); Object obj = Factorybean.create (); Filetransferservice service = (filetransferservice) Obj;return service.downloadfile2 (myFile);} Public MyFile downloadFile2 (MyFile MyFile) throws Filetransferexception {InputStream are = null;try {is = new fileinputstre AM (Myfile.getserverfile ()); Is.skip (Myfile.getposition ()); byte[] bytes = new byte[1024 * 1024];int size = is.read (bytes) if (Size > 0) {byte[] fixedbytes = arrays.copyofrange (bytes, 0, size); Myfile.setbytes (fixedbytes);} else {Myfile.setb Ytes (new byte[0]);}} catch (IOException e) {throw new Filetransferexception (E.getmessage (), e);} finally {ioutils.closequietly (IS);} return myFile;}}

4. A Simple File transfer exception class

Package Com.cattsoft.baseplatform.webservice.fileltransfer;public class Filetransferexception extends Exception { Private static final Long Serialversionuid = 1l;public filetransferexception () {super ();} Public filetransferexception (String message, Throwable cause) {Super (message, cause);} Public filetransferexception (String message) {super (message);} Public filetransferexception (Throwable cause) {super (cause);}}

5. The following is the server class used to publish the Web service

Package Com.cattsoft.baseplatform.webservice.fileltransfer;import Javax.xml.ws.endpoint;public Class filetransferserver {public static void main (string[] args) throws Exception {endpoint.publish ("http://localhost:9000/ Ws/jaxws/filetransferservice ", New Filetransferserviceimpl ());//Endpoint.publish (Args[0], new Filetransferserviceimpl ());}}

6. Finally, the client class is used to send file uploads and download requests.

Package com.cattsoft.baseplatform.webservice.fileltransfer;/* * UploadFile is uploaded from Clientfile to Serverfile * DownloadFile is transmitted from Serverfile to Clientfile * Parameters args[0], args[1],args[2] in turn, address, Clientfile, Serverfile */public class filetransferclient {private static final String address = "Http://192.168.100.169:9000/ws/jaxws/fileTransferService1" ;p rivate static final String clientfile = "F:/ftp/test.txt";p rivate static final String serverfile = "d:/share/portal_esb/ Ftp/test.txt ";p ublic static void Main (string[] args) throws Exception {Long start = System.currenttimemillis (); Filetransferserviceimpl FTS = new Filetransferserviceimpl () Fts.uploadfile (Args[0], args[1], args[2]);//DownloadFile (Args[0], args[1], args[2]); Long stop = System.currenttimemillis (); System.out.println ("Time:" + (Stop-start));}}
