webservices系列(二)——JAX-WS檔案上傳下載

新建ImgData類,存放檔案javabean
DataHandler:使用這個型別存放檔案
Webservice介面,@XmlRootElement(name="ImaData") @XmlAccessorType(XmlAccessType.FIELD) public class ImgData { private Integer id; @XmlMimeType("application/octet-stream") private DataHandler imgData; //檔案 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(name="iHello2")
@SOAPBinding(style = SOAPBinding.Style.RPC)
@MTOM
public interface IHello2 {
public void printContext();
public ImgData getById(@WebParam(name="imgData")ImgData imgData);
}
實現類
這裡需要在f盤下放一個“原檔案.png”的檔案,當然也可以改@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 + "原檔案.png"); System.out.println(file.exists()); custom.setImgData(new DataHandler(new FileDataSource(file))); } return custom; } }
建立webservice類SoapService2,執行
public class SoapService2 {
public static void main(String[] args) {
Endpoint.publish("http://localhost:8080/HelloService2", new IHello2Imp());
System.out.println("run success");
}
}
生成客戶端程式碼
在cmd使用wsimport -p com.lc.client2 -keep http://localhost:8080/HelloService2?wsdl
建立客戶端類SoapClient.java,執行
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];//一次讀取1024byte
int i = 0;
while((i = is.read(bytes)) != -1){
os.write(bytes, 0, i);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
執行結果
