大家好,又见面了,我是你们的朋友全栈君。
一、创建Soap
代码示例如下:
@Test
public void createSoap() throws Exception{
// 创建消息工厂
MessageFactory factory = MessageFactory.newInstance();
// 通过工厂创建Soap的消息
SOAPMessage message = factory.createMessage();
// 获取SoapPart
SOAPPart part = message.getSOAPPart();
// 获取Soap信封Envelope
SOAPEnvelope envelope = part.getEnvelope();
// 通过Soap信封获取body和header的信息
SOAPBody body = envelope.getBody();
// 根据QName创建相应的节点(QName就是一个带有命名空间的节点:<ns:add xmls="http://www.xilen.com/webservice"/> )
QName qname = new QName("http://webservice.xilen.com", "add", "ns");
//通过soapBody传入QName添加body元素
SOAPBodyElement bodyElement = body.addBodyElement(qname);
// 对body添加子元素 (或者直接对body元素设置值:bodyElement.setValue("5"); )
SOAPElement childElement = bodyElement.addChildElement("a");
// 对body子元素设置值
childElement.setValue("7");
// 继续添加第二个子元素 (或者继续对子元素添加子元素:childElement.addChildElement("acn").setValue("acv");)
bodyElement.addChildElement("b").setValue("5");
// 打印最终得到的Soap消息
message.writeTo(System.out);
}
得到的Soap消息如下:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<ns:add xmlns:ns="http://webservice.xilen.com">
<a>7</a>
<b>5</b>
</ns:add>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
二、发送Soap消息
1、基于MESSAGE的方式
代码示例如下:
@Test
public void sendSoapByMessage() throws Exception{
/**
* 定义相关变量(wsdl文档的路径、接口的命名空间、实现的命名空间)
*/
String wsdlUrl = "http://localhost:8888/user?wsdl";
String implNS = "http://impl.soap.xilen.com/";
String inteNS = "http://soap.xilen.com/";
/**
* 创建服务
*/
URL url = new URL(wsdlUrl);
// 通过wsdl实现部分的命名空间创建服务的QNane,因为Service的描述在实现部分的命名空间中(详见 六、附录 中的截图)
QName serviceQname = new QName(implNS, "UserServiceImplService");
Service service = Service.create(url, serviceQname);
/**
* 创建Dispatch (通过SOAPMessage传递)
*/
Dispatch<SOAPMessage> dispatch =
// portName:wsdl文件中Service节点中的prot的name属性值的QName; type:消息类型; mode:消息传递的类型(message|payLoad)
service.createDispatch(new QName(implNS, "UserServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);
/**
* 创建SoapMessage
*/
SOAPMessage message = MessageFactory.newInstance().createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();
// 通过wsdl接口部分的命名空间创建消息的QNane,因为Message的描述在接口部分的命名空间中<span style="font-family: Arial, Helvetica, sans-serif;">(详见 六、附录 中的截图)</span>
QName soapQname = new QName(inteNS, "login", "ns");
SOAPBodyElement bodyElement = body.addBodyElement(soapQname);
bodyElement.addChildElement("name").setValue("admin");
bodyElement.addChildElement("pass").setValue("12345");
/**
* 输出即将发送的Soap消息
*/
message.writeTo(System.out);
System.out.println("-------------------------- out 分隔线 in ----------------------------------");
/**
* 通过dispatch传递消息
*/
SOAPMessage responseMessage = dispatch.invoke(message);
/**
* 输出返回的Soap消息
*/
responseMessage.writeTo(System.out);
/**
* 处理返回的Soap消息得到需要的信息
*/
String result = responseMessage.getSOAPBody().getElementsByTagName("loginResult").item(0).getTextContent();
// 或者采用如下方式得到需要的信息
// String result = responseMessage.getSOAPPart().getEnvelope().getBody().extractContentAsDocument().
// getElementsByTagName("addResult").item(0).getTextContent();
/**
* 输出通过返回Soap消息得到的信息
*/
System.out.println("return-->" + result);
}
Soap消息如下:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<ns:login xmlns:ns="http://soap.xilen.com/">
<name>admin</name>
<pass>12345</pass>
</ns:login>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
<!-------------------------- out 分隔线 in ---------------------------------->
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Header/>
<S:Body>
<ns2:loginResponse xmlns:ns2="http://soap.xilen.com/">
<loginResult>admin, welcome!</loginResult>
</ns2:loginResponse>
</S:Body>
</S:Envelope>
2、基于PAYLOAD的方式
代码示例如下:
@Test
public void sendSoapByPayload() throws Exception{
/**
* 定义相关变量(wsdl文档的路径、接口的命名空间、实现的命名空间)
*/
String wsdlUrl = "http://localhost:8888/user?wsdl";
String implNS = "http://impl.soap.xilen.com/";
String inteNS = "http://soap.xilen.com/";
/**
* 创建服务
*/
URL url = new URL(wsdlUrl);
// 通过wsdl实现部分的命名空间创建服务的QNane,因为Service的描述在实现部分的命名空间中
QName serviceQname = new QName(implNS, "UserServiceImplService");
Service service = Service.create(url, serviceQname);
/**
* 创建Dispatch (通过Source传递)
*/
Dispatch<Source> dispatch =
// portName:wsdl文件中Service节点中的prot的name属性值的QName; type:消息类型; mode:消息传递的类型(message|payLoad)
service.createDispatch(new QName(implNS, "UserServiceImplPort"), Source.class, Service.Mode.PAYLOAD);
/**
* 根据对象通过JAXB创建XML
*/
User user = new User(1L, "TestName", "TestPass");
JAXBContext context = JAXBContext.newInstance(User.class);
Marshaller marshaller = context.createMarshaller();
// 取消xml的文档头和尾
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
StringWriter writer = new StringWriter();
marshaller.marshal(user, writer);
/**
* 组建soap的xml
*/
String payload = "<ns:register xmlns:ns=\"" + inteNS + "\">" + writer.toString() + "</ns:register>";
System.out.println(payload);
/**
* 创建Source
*/
Source outSource = new StreamSource(new StringReader(payload));
/**
* 通过dispatch传递负载(payLoad)
*/
Source inSource = dispatch.invoke(outSource);
/**
* 将响应的Source转化为DOM进行操作获取需要的信息 (使用Transform对象转换)
*/
Transformer transformer = TransformerFactory.newInstance().newTransformer();
DOMResult result = new DOMResult();
transformer.transform(inSource, result);
// 使用xpath查询
XPath path = XPathFactory.newInstance().newXPath();
NodeList nl = (NodeList) path.evaluate("//registerResult", result.getNode(), XPathConstants.NODESET);
// 打印需要被获取的信息
System.out.println(nl.item(0).getTextContent());
}
组建的Soap内容如下:
<ns:register xmlns:ns="http://soap.xilen.com/">
<user>
<id>1</id>
<name>TestName</name>
<pass>TestPass</pass>
</user>
</ns:register>
三、列表响应处理
@Test
public void returnList() throws Exception{
/**
* 定义相关变量(wsdl文档的路径、接口的命名空间、实现的命名空间)
*/
String wsdlUrl = "http://localhost:8888/user?wsdl";
String implNS = "http://impl.soap.xilen.com/";
String inteNS = "http://soap.xilen.com/";
/**
* 创建服务
*/
URL url = new URL(wsdlUrl);
// 通过wsdl实现部分的命名空间创建服务的QNane,因为Service的描述在实现部分的命名空间中
QName serviceQname = new QName(implNS, "UserServiceImplService");
Service service = Service.create(url, serviceQname);
/**
* 创建Dispatch
*/
Dispatch<SOAPMessage> dispatch =
// portName:wsdl文件中Service节点中的prot的name属性值的QName type:消息类型 mode:消息传递的类型(message | payLoad)
service.createDispatch(new QName(implNS, "UserServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);
/**
* 创建SoapMessage
*/
SOAPMessage message = MessageFactory.newInstance().createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();
QName soapQname = new QName(inteNS, "list", "ns");
SOAPBodyElement bodyElement = body.addBodyElement(soapQname);
/**
* 通过dispatch传递消息
*/
SOAPMessage responseMessage = dispatch.invoke(message);
// 转换body为document
NodeList nodeList = responseMessage.getSOAPPart().getEnvelope().getBody().
extractContentAsDocument().getElementsByTagName("user");
JAXBContext ctx = JAXBContext.newInstance(User.class);
// Jaxb转换Node为User
for (int i = 0; i < nodeList.getLength(); i++) {
User u = (User) ctx.createUnmarshaller().unmarshal(nodeList.item(i));
System.out.println(u);
}
}
四、显示配置Header
示例代码如下:
@Test
public void sendSoapAddHeader() throws Exception{
/**
* 定义相关变量(wsdl文档的路径、接口的命名空间、实现的命名空间)
*/
String wsdlUrl = "http://localhost:8888/user?wsdl";
String implNS = "http://impl.soap.xilen.com/";
String inteNS = "http://soap.xilen.com/";
/**
* 创建服务
*/
URL url = new URL(wsdlUrl);
QName serviceQname = new QName(implNS, "UserServiceImplService");
Service service = Service.create(url, serviceQname);
/**
* 创建Dispatch
*/
Dispatch<SOAPMessage> dispatch =
service.createDispatch(new QName(implNS, "UserServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);
/**
* 创建SoapMessage
*/
SOAPMessage message = MessageFactory.newInstance().createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();
QName soapQname = new QName("http://soap.xilen.com/", "check", "ns");
body.addBodyElement(soapQname);
/**
* 添加Header
*/
SOAPHeader header = envelope.getHeader();
// 判断是否有Header,没有则添加
if(header == null){
header = envelope.addHeader();
}
// 添加Header的内容
QName headerQName = new QName("http://soap.xilen.com/", "name", "nn");
SOAPHeaderElement headerElement = header.addHeaderElement(headerQName);
headerElement.setValue("admin");
header.addHeaderElement(new QName("http://soap.xilen.com/", "pass", "nn")).setValue("12345");
message.writeTo(System.out);
/**
* 通过dispatch传递消息
*/
SOAPMessage responseMessage = dispatch.invoke(message);
/**
* 处理响应
*/
NodeList nodeList = responseMessage.getSOAPPart().getEnvelope().getBody().
extractContentAsDocument().getElementsByTagName("user");
JAXBContext ctx = JAXBContext.newInstance(User.class);
System.out.println("\n" + (User) ctx.createUnmarshaller().unmarshal(nodeList.item(0)));
}
发送的Soap如下:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<nn:name xmlns:nn="http://soap.xilen.com/">admin</nn:name>
<nn:pass xmlns:nn="http://soap.xilen.com/">12345</nn:pass>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<ns:check xmlns:ns="http://soap.xilen.com/" />
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
五、服务端抛出异常
@Test
public void throwsException() throws Exception{
/**
* 定义相关变量(wsdl文档的路径、接口的命名空间、实现的命名空间)
*/
String wsdlUrl = "http://localhost:8888/user?wsdl";
String implNS = "http://impl.soap.xilen.com/";
String inteNS = "http://soap.xilen.com/";
/**
* 创建服务
*/
URL url = new URL(wsdlUrl);
QName serviceQname = new QName(implNS, "UserServiceImplService");
Service service = Service.create(url, serviceQname);
/**
* 创建Dispatch
*/
Dispatch<SOAPMessage> dispatch =
service.createDispatch(new QName(implNS, "UserServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);
/**
* 创建SoapMessage
*/
SOAPMessage message = MessageFactory.newInstance().createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();
QName soapQname = new QName(inteNS, "throwsException", "ns");
body.addBodyElement(soapQname);
/**
* try异常
*/
try {
dispatch.invoke(message);
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
