WebService 程式如下
@WebMethod
public void upload(@WebParam(name = "fileName")String fileName, byte[] imageBytes) {
String filePath = "d:/MsgServerUpload/" + fileName;
try {
FileOutputStream fos = new FileOutputStream(filePath);
BufferedOutputStream outputStream = new BufferedOutputStream(fos);
outputStream.write(imageBytes);
outputStream.close();
System.out.println("Received file: " + filePath);
} catch (IOException ex) {
System.out.println("Exception from here");
System.err.println(ex);
throw new WebServiceException(ex);
}
}
@WebMethod
public byte[] download(String fileName) {
String filePath = "d:/MsgServerDownload/" + fileName;
System.out.println("Sending file: " + filePath);
try {
File file = new File(filePath);
FileInputStream fis = new FileInputStream(file);
BufferedInputStream inputStream = new BufferedInputStream(fis);
byte[] fileBytes = new byte[(int) file.length()];
inputStream.read(fileBytes);
inputStream.close();
return fileBytes;
} catch (IOException ex) {
System.err.println(ex);
throw new WebServiceException(ex);
}
}
請容許我稍微解釋一下這2個Method的路徑，d:/MsgServerUpload/ 是指 user在呼叫WS後，會將使用者上傳的的檔案放在Web Server的該路徑下，也就是說上傳的檔案都會放在這裡啦!
那d:/MsgServerDownload/當然是我在Server上放的要供使用者download的目錄
也就是，使用者upload or download的路徑我都事先預設好了，當然你的Web Server下要有該目錄喔!
接著我們可以寫個Java版的測試WS是否可呼叫成功
完整的程式碼如下，我用的方式必須先將WS利用NetBean開WS Build成WSClient.jar才能呼叫API
package com.sti.ws.test;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.xml.namespace.QName;
import com.sti.web.msg.webservice.Exception_Exception;
import com.sti.web.msg.webservice.MSGWebService;
import com.sti.web.msg.webservice.MSGWebService_Service;
public class TestWS {
public static void main(String[] args) {
MSGWebService msgws = getMsgWS();
try {
String fileName = "test.txt";
String filePath = "d:/YourLocalFileFolder/" + fileName;
File file = new File(filePath);
FileInputStream fis = new FileInputStream(file);
BufferedInputStream inputStream = new BufferedInputStream(fis);
byte[] imageBytes = new byte[(int) file.length()];
inputStream.read(imageBytes);
msgws.upload(file.getName(), imageBytes);
inputStream.close();
System.out.println("File uploaded: " + filePath);
} catch (IOException ex) {
ex.printStackTrace();
System.err.println(ex);
}
try {
//指定要download的檔名
String fileName = "test1.txt";
//要求download到哪裡
String filePath = "d:/YourLocalDownloadFolder/" + fileName;
byte[] fileBytes = msgws.download(fileName);
FileOutputStream fos = new FileOutputStream(filePath);
BufferedOutputStream outputStream = new BufferedOutputStream(fos);
outputStream.write(fileBytes);
outputStream.close();
System.out.println("File downloaded: " + filePath);
} catch (IOException ex) {
System.err.println(ex);
}*/
}
private final static String MSGWS_WSDL_LOCATION;
private final static String MSGWS_QName;
private final static String MSGWS_qname;
static {
MSGWS_WSDL_LOCATION = "http://192.168.73.1:7001/YourWebService?wsdl";
MSGWS_QName = "http://webservice.msg.web.sti.com/";
MSGWS_qname = "MSGWebService";
}
public static MSGWebService getMsgWS() {
if(MSGWS_WSDL_LOCATION == null || "".equals(MSGWS_WSDL_LOCATION)) {
} else {
try {
URL url = new URL(MSGWS_WSDL_LOCATION);
QName qname = new QName(MSGWS_QName, MSGWS_qname);
MSGWebService service = new MSGWebService_Service(url, qname).getMSGWebServicePort();
System.out.println("OK");
return service;
} catch(MalformedURLException me) {
System.out.println("Fail");
me.printStackTrace();
System.out.println(me.getMessage());
}
}
return null;
}
}
我在範例測試程式裡，將我Local下的 test.txt檔案上傳，上傳成功後，您會發現你的Web Server下的d:/MsgServerUpload/有你剛才上傳的檔案，
而在download的範例程式，我假設在Web Server的d:/MsgServerDownload/目錄下
有一個檔案叫做 test1.txt，注意你必須先做好一個檔案放至此目錄下
接著指定我要download到我Local的d:/YourLocalDownloadFolder/ 路徑下就會出現一個叫做test1.txt的檔案了
為什麼我要分開目錄呢，是為了區別來自於不同的程式，你可以把WS程式的目錄指向同一個，也就是說自己Local上傳的檔案，也可以透過WS自己DownLoad回來。
Cheers
