运用AXIS实现文件传输（转）

使用AXIS实现文件传输（转）
Server端代码：

package org.demo.yuzp.file;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

import javax.activation.DataHandler;

public class FileReceiverServer {
public String receive(DataHandler handler, String fileName){
  File file = new File(fileName);
  if (handler == null || fileName == null || "".equals(fileName)){
   return "errors";
  }
 
  InputStream input = null;
  FileOutputStream fos = null;
 
  try {
   input = handler.getInputStream();
   fos = new FileOutputStream(file);
  
   byte[] buffer = new byte[1024];
   while (input.read(buffer) != -1){
    fos.write(buffer);
   }
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } finally{
   if (input != null){
    try {
     input.close();
    } catch (IOException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
   }
  
   if (fos != null){
    try {
     fos.close();
    } catch (IOException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
   }
  }
 
  return "Success file saved on server, at: " + file.getAbsolutePath();
 
}
}




　　server-config.wsdd

<service name="FileReceiverServer" provider="java:RPC"> <parameter name="className" value="org.demo.yuzp.file.FileReceiverServer" /> <parameter name="allowedMethods" value="*" /> <parameter name="scope" value="session" /> <operation name="receive" qname="ns:receive" xmlns:ns="receive" returnType="rtns:string" xmlns:rtns="http://www.w3.org/2001/XMLSchema"> <parameter name="handler" type="tns:string" xmlns:tns="http://www.w3.org/2001/XMLSchema" /> <parameter name="fileName" type="myns:DataHandler" xmlns:tns="http://www.w3.org/2001/XMLSchema" /> </operation> <typeMapping qname="myns:DataHandler" xmlns:myns="DataHandler" 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>

　　 看了deploy配置文件后，大家也许会问，DataHandler就是用来作文件序列化操作的，那为什么在wsdd文件中还要配置文件序列化/反序列化器呢？

　　这是因为DataHandler本身是需要序列化和反序列化的，所以必须要用Axis提供的序列化/反序列化器JAFDataHandlerSerializerFactory和JAFDataHandlerDeserializerFactory来进行序列化/反序列化操作。

　　Client端代码：

package org.demo.yuzp.file;

import java.rmi.RemoteException;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.encoding.XMLType;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory;
import org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory;

public class FileSenderClient {

/**
  * @param args
  */
public static void main(String[] args) {
  String fileName = "readme.txt";
  DataHandler dh = new DataHandler(new FileDataSource(
    FileSenderClient.class.getResource(fileName).getPath()));
  System.out.println("PATH:" +
    FileSenderClient.class.getResource(fileName).getPath());
 
  String url = "http://localhost:8080/axis1/services/FileReceiverServer";
  Service serv = new Service();
  try {
   Call call = (Call)serv.createCall();
   call.setTargetEndpointAddress(url);
   call.setOperationName(new QName(url, "receive"));
   QName qn = new QName("DataHandler", "myns:DataHandler");
   call.registerTypeMapping(DataHandler.class, qn, JAFDataHandlerSerializerFactory.class, JAFDataHandlerDeserializerFactory.class);
   call.addParameter("s1", qn, ParameterMode.IN);
   call.addParameter("s2", XMLType.XSD_STRING, ParameterMode.IN);
   call.setReturnClass(String.class);
   String result = (String)call.invoke(new Object[]{dh, fileName});
   System.out.println("result: " + result);
  } catch (ServiceException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (RemoteException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 
 
}

}


当运行完Client代码后，会在Console中显示出：

Success file saved on server, at:　E:\Eclipse3.4.2\readme.txt
