用Axis2 接受和发送二进制对象的总结

接收：(Server端返回的是一个ObjectPack ObjectPack.name是文件的名称，ObjectPack.bin是byte[]类型的binary)

经过我的测试，类似下面发送的方法用RPCServiceClient.invokeBlocking()得到byte[],然后转化成文件这样不行，只好用以下的方式：

EndpointReference targetEPR = new EndpointReference(

"http://localhost:8080/services/Pic");

OMFactory fac = OMAbstractFactory.getOMFactory();

OMNamespace omNs = fac.createOMNamespace(

"http://pic.webservice.com", "get");

OMElement data = fac.createOMElement("get", omNs);

OMElement name= fac.createOMElement("name", omNs);

email.setText("avatar.png");

data.addChild(email);

ServiceClient sender = new ServiceClient();

Options options =sender.getOptions();

options.setSoapVersionURI(SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI);

options.setTo(targetEPR);

// enabling MTOM in the client side

options.setProperty(Constants.Configuration.ENABLE_MTOM,

Constants.VALUE_TRUE);

options.setTransportInProtocol(Constants.TRANSPORT_HTTP);

System.out.println(data);

OMElement ome = sender.sendReceive(data);

Iterator ite = ome.getFirstElement().getChildElements();

String fileName = "avatar.png";

int counter = 0;

while (ite.hasNext()) {

OMElement e = ite.next();

if (counter++ == 0) {

fileName = e.getText();

System.out.println(fileName);

} else {

OMText binaryNode = (OMText) e.getFirstOMChild();

binaryNode.setOptimize(true);// 必须加此句，否则会出现ContentID is null的异常!

DataHandler actualDH = (DataHandler) binaryNode

.getDataHandler();

FileOutputStream fos = new FileOutputStream(new File("E:\\"

+ fileName));

InputStream is = actualDH.getInputStream();

byte[] b = new byte[1024];

while (true) {

int i = is.read(b);

if (i == -1)

break;

fos.write(b, 0, i);

}

fos.flush();

fos.close();

is.close();

}

}

发送：(Server端接收的是参数是name:文件名称, byte[] b)

经过我的测试，用上面的ServerClient的方式，用DataHandler 会报错，只好用RPCServiceClient

RPCServiceClient serviceClient = new RPCServiceClient();

Options options = serviceClient.getOptions();

EndpointReference targetEPR = new EndpointReference(

"http://localhost:8080/Pic");

options.setTo(targetEPR);

File file = new File("E:\\avatar.png");

FileInputStream fin = new FileInputStream(file);

byte[] b = new byte[(int) file.length()];

fin.read(b, 0, b.length);

fin.close();

Object[] opAddEntryArgs = new Object[] { "name", b };

Class[] classes = new Class[] { Boolean.class };

QName opAddEntry = new QName(

"http://pic.webservice.com",

"changeMessengerDisplayPic");

Boolean result = (Boolean) serviceClient.invokeBlocking(opAddEntry,

opAddEntryArgs, classes)[0];

System.out.println("result:" + result);
