要使用Java操作和发送SOAP消息,您可以使用Java内置的SOAP API或第三方库。以下是使用Java内置的SOAP API的一些步骤:
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
// 设置命名空间
soapEnvelope.addNamespaceDeclaration("ns", "http://example.com/namespace");
// 创建SOAP消息体
SOAPBody soapBody = soapEnvelope.getBody();
SOAPElement soapElement = soapBody.addChildElement("MyRequest", "ns");
SOAPElement childElement = soapElement.addChildElement("Parameter");
childElement.setTextContent("Value");
String endpointUrl = "http://example.com/soap-endpoint";
SOAPMessage soapResponse = soapConnection.call(soapMessage, endpointUrl);
SOAPPart soapPart = soapResponse.getSOAPPart();
SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
// 获取SOAP响应体
SOAPBody soapBody = soapEnvelope.getBody();
Iterator<SOAPElement> iterator = soapBody.getChildElements("MyResponse", "ns");
while (iterator.hasNext()) {
SOAPElement soapElement = iterator.next();
// 处理SOAP响应数据
}
最后,记得关闭SOAP连接。
soapConnection.close();
使用第三方库也是一种选择,如Apache Axis、Apache CXF等。这些库提供了更丰富的功能和更简化的API来处理SOAP消息。您可以根据自己的需求选择适合您的库和方法。
