WEB后台@JAX-WS

将二进制数据放到Attachment中进行传递，而不是放到SOAPBODY进行传递

xsd文件中定义二进制数据类型

<xsd:element type="tns:upload" name="upload"/> 
<xsd:element type="tns:uploadResponse" name="uploadResponse"/> 
<xsd:complexType name="upload"> 
 <xsd:sequence> 
  <xsd:element type="xsd:base64Binary" name="file" minOccurs="0"/> 
 </xsd:sequence> 
</xsd:complexType> 
<xsd:complexType name="uploadResponse"> 
 <xsd:sequence/> 
</xsd:complexType>

第一种方式：

服务端 @MOTM

客户端 new MTOMFeature(true)

接口参数：byte[] file

1.使用附件的形式传递二进制数据

接口

package com.hqh.service;

import java.util.List;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;

import com.hqh.model.User;


/**
 * This class was generated by the JAX-WS RI.
 * JAX-WS RI 2.1.6 in JDK 6
 * Generated source version: 2.1
 * 
 */
@WebService(name = "IUserService", targetNamespace = "http://service.hqh.com")

public interface IUserService {

    /**
     * 文件上传服务
     * @param file
     */
    @WebMethod
    @RequestWrapper(localName = "upload", targetNamespace = "http://service.hqh.com", className = "com.hqh.service.Upload")
    @ResponseWrapper(localName = "uploadResponse", targetNamespace = "http://service.hqh.com", className = "com.hqh.service.UploadResponse")
    public void upload(
        @WebParam(name = "file", targetNamespace = "http://service.hqh.com")
        byte[] file);
}

服务器端实现类上增加MTOM注解

@WebService(endpointInterface="com.hqh.service.IUserService",
			wsdlLocation="WEB-INF/wsdl/user.wsdl",
			serviceName="UserService",
			portName="userServicePort",
			targetNamespace="http://service.hqh.com")
@MTOM
public class UserServiceImpl implements IUserService {
	

	@Override
	public void upload(byte[] data) {
		FileOutputStream os = null;
		try {
			os = new FileOutputStream("E:/technology-hqh/proj/webservice/a.tmp");
			os.write(data);
			os.flush();
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			if(os!=null) {
				try {
					os.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
		
	}

}

客户端

import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.ws.soap.MTOMFeature;

import org.apache.commons.io.FileUtils;
import org.junit.Before;

import com.hqh.service.IUserService;
import com.hqh.service.UserService;



public class Test {
	private UserService service ;
	private IUserService iservice ;
	@Before
	public void init() {
		try {
			URL url = new URL("http://localhost:8888/Demo/service");
			QName name = new QName("http://service.hqh.com", "UserService");
			service = new UserService(url,name);
			//开启MTOM功能，二进制文件将以附件形式传递
			iservice = service.getUserServicePort(new MTOMFeature(true));
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
	}
	
	@org.junit.Test
	public void testUpload() {
		try {
			String path1="E:/technology-hqh/proj/webservice/35_二进制的处理（使用MTOM）.avi";
			String path2="D:/scott.dmp";
			byte[] data = FileUtils.readFileToByteArray(
					new File(path2));
			iservice.upload(data);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

使用Eclipse的TCPM监控可观察到数据传输过程：

第二种方式：

服务端 @BindingType(SOAPBinding.SOAP11HTTP_MTOM_BINDING)

客户端 DataHandler

接口参数：DataHandler handler

1.xsd

<!-- 文件上传 -->

<xsd:element type="tns:uploadResponse" name="uploadResponse"/> 
<xsd:complexType name="upload">
