SOAP服务开发示例：使用Java实现服务端和客户端

SOAP服务开发示例：使用Java实现服务端和客户端

SOAP协议版本： 1.1、1.2

传输层协议： HTTP

安全标准： Web Service的安全策略

方法名： ckts_bgdInfo

命名空间： http://ws.dc.com

接口URL自定义,如： http://ip:port/services/recv?wsdl

消息模板：

<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:ws='http://ws.dc.com'>
   <soapenv:Header/>
   <soapenv:Body>
      <ws:ckts_bgdInfo>
         <ws:xml>报文</ws:xml>
      </ws:ckts_bgdInfo>
   </soapenv:Body>
</soapenv:Envelope>

服务端代码

package com.dc.ws;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.xml.ws.Endpoint;

@WebService
public class SampleService {
    @WebMethod
    public String ckts_bgdInfo(@WebParam(name = "xml") String xml) {
        // 在这里处理接收到的报文
        return "处理结果";
    }

    public static void main(String[] args) {
        String url = "http://localhost:8080/services/recv";
        SampleService service = new SampleService();
        Endpoint.publish(url, service);
        System.out.println("SOAP服务已启动，访问地址：" + url);
    }
}

客户端代码

package com.dc.ws;

import javax.xml.namespace.QName;
import javax.xml.soap.*;
import java.io.ByteArrayOutputStream;
import java.io.IOException;

public class SampleClient {
    private static final String SERVICE_URL = "http://localhost:8080/services/recv?wsdl";
    private static final String NAMESPACE_URI = "http://ws.dc.com";
    private static final String METHOD_NAME = "ckts_bgdInfo";

    public static void main(String[] args) {
        try {
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            MessageFactory messageFactory = MessageFactory.newInstance();
            SOAPMessage soapMessage = messageFactory.createMessage();

            SOAPPart soapPart = soapMessage.getSOAPPart();

            SOAPEnvelope envelope = soapPart.getEnvelope();
            envelope.addNamespaceDeclaration("ws", NAMESPACE_URI);

            SOAPBody soapBody = envelope.getBody();
            SOAPElement soapElement = soapBody.addChildElement(METHOD_NAME, "ws");
            SOAPElement xmlElement = soapElement.addChildElement("xml");
            xmlElement.addTextNode("报文");

            soapMessage.saveChanges();

            SOAPMessage soapResponse = soapConnection.call(soapMessage, SERVICE_URL);

            ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
            soapResponse.writeTo(outputStream);
            String response = new String(outputStream.toByteArray());
            System.out.println("服务端返回：" + response);

            soapConnection.close();
        } catch (SOAPException | IOException e) {
            e.printStackTrace();
        }
    }
}

注意： 替换服务端和客户端代码中的URL和命名空间为实际的值。然后，运行服务端代码启动SOAP服务，再运行客户端代码进行测试。

总结：

该示例提供了一个简单的SOAP服务实现，演示了如何使用SOAP API进行服务调用。通过修改代码中的URL、命名空间和方法名，可以轻松地实现不同的SOAP服务。
