2. 整体流程
下面是实现Java代码调用SOAP的整体流程:
步骤 | 描述 |
---|---|
1 | 创建SOAP客户端 |
2 | 准备SOAP请求 |
3 | 发送SOAP请求 |
4 | 接收SOAP响应 |
5 | 解析SOAP响应 |
3. 具体步骤及代码示例
步骤1:创建SOAP客户端
// 创建一个新的SOAP客户端
SOAPConnectionFactory factory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = factory.createConnection();
步骤2:准备SOAP请求
// 创建一个新的SOAP消息
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage message = messageFactory.createMessage();
// 创建SOAP消息的部分:信封
SOAPPart soapPart = message.getSOAPPart();
// 创建SOAP信封的主体
SOAPEnvelope envelope = soapPart.getEnvelope();
envelope.addNamespaceDeclaration("example", "
// 创建SOAP消息的主体
SOAPBody body = envelope.getBody();
SOAPElement bodyElement = body.addChildElement("getStockPrice", "example");
bodyElement.addChildElement("stockSymbol").addTextNode("AAPL");
步骤3:发送SOAP请求
// 创建目标SOAP地址
String url = "
// 发送SOAP请求并获取响应
SOAPMessage response = connection.call(message, url);
步骤4:接收SOAP响应
// 检查响应是否成功
if (response.getSOAPBody().hasFault()) {
System.out.println(response.getSOAPBody().getFault().getFaultString());
} else {
System.out.println("SOAP调用成功!");
}
步骤5:解析SOAP响应
// 解析SOAP响应
SOAPBody responseBody = response.getSOAPBody();
String stockPrice = responseBody.getElementsByTagName("stockPrice").item(0).getTextContent();
System.out.println("股票价格为:" + stockPrice);
