WebService处理传递普通的信息，还可以传输文件，下面介绍WebService是怎么完成文件传输的。
1、 首先编写服务器端上传文件的WebService方法
package com.hoo.import java.io.Fimport java.io.FileNotFoundEimport java.io.FileOutputSimport java.io.InputSimport javax.activation.DataH/** * &b&function:&/b&Axis WebService完成文件上传服务器端 * @author hoojo * @createDate Dec 18, :16 PM * @file UploadFileService.java * @package com.hoo.service * @project AxisWebService * @blog http://blog.csdn.net/IBM_hoojo * @email hoojo_@ * @version 1.0 */public class UploadFileService {
* &b&function:&/b&传递文件
* @author hoojo
* @createDate Dec 18, :58 PM
* @param handler DataHandler这个参数必须
* @param fileName 文件名称
* @return upload Info
public String upload(DataHandler handler, String fileName) {
if (fileName != null && !"".equals(fileName)) {
File file = new File(fileName);
if (handler != null) {
InputStream is = null;
FileOutputStream fos = null;
is = handler.getInputStream();
fos = new FileOutputStream(file);
byte[] buff = new byte[1024 * 8];
int len = 0;
while ((len = is.read(buff)) & 0) {
fos.write(buff, 0, len);
} catch(FileNotFoundException e) {
return "fileNotFound";
} catch (Exception e) {
return "upload File failure";
} finally {
if (fos != null) {
fos.flush();
fos.close();
if (is != null) {
is.close();
} catch (Exception e) {
e.printStackTrace();
return "file absolute path:" + file.getAbsolutePath();
return "handler is null";
return "fileName is null";
上传方法和我们以前在Web中上传唯一不同的就是参数一DataHandler，可以将这类看成文件传输器，他可以把文件序列化。然后通过DataHandler可以得到一个输入流InputStream，通过这个流可以读到文件的内容。其他的操作和普通上传类似。
2、 定制wsdd发布文件上传的WebService服务
&?xml version="1.0" encoding="UTF-8"?&&deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"&
&service name="UploadFile" provider="java:RPC"&
&parameter name="className" value="com.hoo.service.UploadFileService" /&
&parameter name="allowedMethods" value="*" /&
&parameter name="scope" value="Session" /&
&!-- 和服务器端上传文件的方法签名对应，参数也对应 --&
&operation name="upload" qname="operNS:upload" xmlns:operNS="upload" returnType="rns:string"
xmlns:rns="http://www.w3.org/2001/XMLSchema"&
&parameter name="handler" type="ns:DataHandler" xmlns:ns="http://www.w3.org/2001/XMLSchema"/&
&parameter name="fileName" type="ns:string" xmlns:ns="http://www.w3.org/2001/XMLSchema"/&
&/operation&
&typeMapping qname="hns:DataHandler" xmlns:hns="ns:FileUploadHandler"
languageSpecificType="java:javax.activation.DataHandler"
serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory" deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/&
&/service&&/deployment&
上面才xml节点元素在前面都见过了，说明下operation中的参数，注意要指定参数类型，特别是DataHandler的类型，然后就是typeMapping的serializer、deserializer的序列化和反序列化工厂类的配置。
3、 用dos命令发布当前WebService
C:\SoftWare\tomcat-5.0.28\tomcat-5.0.28\webapps\AxisWebService\WEB-INF&java -Djava.ext.dirs=lib org.apache.axis.client.AdminClient -lhttp://localhost:8080/AxisWebService/services/AdminService deployUpload.wsdd
发布完成后，可以通过这个地址查看uploadFile这个service了
4、 编写客户端代码
package com.hoo.import java.rmi.RemoteEimport javax.activation.DataHimport javax.activation.FileDataSimport javax.xml.namespace.QNimport javax.xml.rpc.ParameterMimport javax.xml.rpc.ServiceEimport org.apache.axis.client.Cimport org.apache.axis.client.Simport org.apache.axis.encoding.XMLTimport org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFimport org.apache.axis.encoding.ser.JAFDataHandlerSerializerF/** * &b&function:&/b&上传文件WebService客户端 *
* @author hoojo * @createDate Dec 18, :14 PM * @file UploadFileClient.java * @package com.hoo.client * @project AxisWebService * @blog http://blog.csdn.net/IBM_hoojo * @email hoojo_@ * @version 1.0 */public class UploadFileClient {
public static void main(String[] args) throws ServiceException, RemoteException {
String url = "http://localhost:8080/AxisWebService/services/UploadFile";
String fileName = "readMe.txt";
String path = System.getProperty("user.dir") + "\\WebRoot\\" + fileN
System.out.println(path);
//这样就相当于构造了一个带文件路径的File了
DataHandler handler = new DataHandler(new FileDataSource(path));
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(url);
* 注册异常类信息和序列化类 ns:FileUploadHandler 和 wsdd 配置文件中的typeMapping中的xmlns:hns="ns:FileUploadHandler" 的对应 DataHandler
* 和 wsdd 配置文件中的typeMapping中的qname="hns:DataHandler"的DataHandler对应
QName qn = new QName("ns:FileUploadHandler", "DataHandler");
call.registerTypeMapping(DataHandler.class, qn,
JAFDataHandlerSerializerFactory.class,
JAFDataHandlerDeserializerFactory.class);
call.setOperationName(new QName(url, "upload"));
//设置方法形参，注意的是参数1的type的DataHandler类型的，和上面的qn的类型是一样的
call.addParameter("handler", qn, ParameterMode.IN);
call.addParameter("fileName", XMLType.XSD_STRING, ParameterMode.IN);
//设置返回值类型，下面2种方法都可以
call.setReturnClass(String.class);
//call.setReturnType(XMLType.XSD_STRING);
String result = (String) call.invoke(new Object[] { handler, "remote_server_readMe.txt" });
System.out.println(result);
至此，文件传输就完成了。怎么样，还不错吧！
如果你用myEclipse进行开发的话，运行时可能会出现以下的错误:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
原因是jar包版本不统一,解决方法如下:
删除Java EE 5 Libraries/javaee.jar/mail里的包有东西.
具体方法如下:
用rar打开X:/Program Files/MyEclipse 6.0/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_6.0.1.zmyeclipse/data/libraryset/EE_5/javaee.jar,然后删除mail,一切就ok了.
