新建ImgData类，存放文件javabean

DataHandler：使用这个类型存放文件

@XmlRootElement(name="ImaData")
    @XmlAccessorType(XmlAccessType.FIELD)
    public class ImgData {
    	
    	private Integer id;
    	@XmlMimeType("application/octet-stream")
    	private DataHandler imgData;	//文件
    	public Integer getId() {
    		return id;
    	}
    	public void setId(Integer id) {
    		this.id = id;
    	}
    	public DataHandler getImgData() {
    		return imgData;
    	}
    	public void setImgData(DataHandler imgData) {
    		this.imgData = imgData;
    	}
    }

Webservice 接口 ,

@WebService(name="iHello2")
    @SOAPBinding(style = SOAPBinding.Style.RPC)
    @MTOM
    public interface IHello2 {
    	public void printContext();
    	public ImgData getById(@WebParam(name="imgData")ImgData imgData);
    }

实现类

@WebService(serviceName="HelloService",portName="HelloServicePort",
    targetNamespace="http://service.lc.com/",endpointInterface="com.lc.service2.IHello2")
    public class IHello2Imp implements IHello2 {
    
    	@Resource
    	private WebServiceContext context;
    	
    	@Override
    	public void printContext() {
    		MessageContext ctx = context.getMessageContext();
    		Set<String> set = ctx.keySet();
    		for(String key : set) {
    			System.out.println("{" + key + "," + ctx.get(key) + "}");
    			try {
    				System.out.println("key.scope:" + ctx.getScope(key));
    			} catch (Exception e) {
    				System.out.println("scope not found");
    			}
    			
    		}
    	}
    
    	@Override
    	public ImgData getById(ImgData custom) {
    		if(custom.getId() == 1) {
    			File file = new File("f:" + File.separator + "原文件.png");
    			System.out.println(file.exists());
    			custom.setImgData(new DataHandler(new FileDataSource(file)));
    		}
    		return custom;
    	}
    
    }

这里需要在f盘下放一个“原文件.png”的文件，当然也可以改  
创建webservice类SoapService2，运行

public class SoapService2 {
    
    	public static void main(String[] args) {
    		Endpoint.publish("http://localhost:8080/HelloService2", new IHello2Imp());
    		System.out.println("run success");
    	}
    
    }

生成客户端代码

在cmd使用wsimport -p com.lc.client2 -keep http://localhost:8080/HelloService2?wsdl

把文件拷到eclipse对应包下  
创建客户端类SoapClient.java，运行

public class SoapClient {
    	public static void main(String[] args) throws MalformedURLException {
    		QName qName = new QName("http://service.lc.com/", "HelloService");
    		HelloService helloService = new HelloService(new URL("http://localhost:8080/HelloService2?wsdl"), qName);
    		IHello2 hello2 = helloService.getPort(IHello2.class);
    		hello2.printContext();
    		ImgData imgData = new ImgData();
    		imgData.setId(1);
    		ImgData imgData2 = hello2.getById(imgData);
    		DataSource ds = imgData2.getImgData().getDataSource();
    		String ctt = ds.getContentType();
    		System.out.println("ContentType:" + ctt);
    		try {
    			InputStream is = ds.getInputStream();
    			OutputStream os = new FileOutputStream("F:" + File.separator + "t1.png");
    			byte[] bytes = new byte[1024];//一次读取1024byte
    			int i = 0;
    			while((i = is.read(bytes)) != -1){
    				os.write(bytes, 0, i);
    			}
    		} catch (IOException e) {
    			e.printStackTrace();
    		}	
    	}
    }

运行结果
