Java SOAP 协议调用示例：接收、处理和测试 SOAP 请求

以下是使用 Java 模拟接收一个 SOAP 请求，并提供测试验证方法的示例代码：

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@WebService(targetNamespace = "http://ws.dc.com")
public class SOAPService {
    
    @WebMethod(operationName = "ckts_bgdInfo")
    public String handleRequest(@WebParam(name = "xml") String xml) {
        // 在这里处理SOAP请求，并返回响应结果
        return "处理SOAP请求成功";
    }
}

@XmlRootElement(name = "Envelope", namespace = "http://schemas.xmlsoap.org/soap/envelope/")
@XmlType(propOrder = {"header", "body"})
public class SOAPEnvelope {
    
    private SOAPHeader header;
    private SOAPBody body;
    
    @XmlElement(name = "Header")
    public SOAPHeader getHeader() {
        return header;
    }
    
    public void setHeader(SOAPHeader header) {
        this.header = header;
    }
    
    @XmlElement(name = "Body")
    public SOAPBody getBody() {
        return body;
    }
    
    public void setBody(SOAPBody body) {
        this.body = body;
    }
}

@XmlRootElement(name = "Header")
public class SOAPHeader {
    // 可根据实际情况添加需要的属性
}

@XmlRootElement(name = "Body")
@XmlType(propOrder = {"request"})
public class SOAPBody {
    
    private SOAPRequest request;
    
    @XmlElement(name = "ckts_bgdInfo", namespace = "http://ws.dc.com")
    public SOAPRequest getRequest() {
        return request;
    }
    
    public void setRequest(SOAPRequest request) {
        this.request = request;
    }
}

@XmlRootElement(name = "ckts_bgdInfo", namespace = "http://ws.dc.com")
public class SOAPRequest {
    
    private String xml;
    
    public String getXml() {
        return xml;
    }
    
    public void setXml(String xml) {
        this.xml = xml;
    }
}

使用上述代码，你可以创建一个 SOAP 服务，并在其中处理 SOAP 请求。在handleRequest方法中，你可以编写处理 SOAP 请求的逻辑，并返回响应结果。

为了验证上述代码是否正确，你可以使用以下代码进行测试：

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPMessage;

public class SOAPClient {
    
    public static void main(String[] args) {
        try {
            // 创建SOAP连接工厂
            SOAPConnectionFactory connectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection connection = connectionFactory.createConnection();
            
            // 创建SOAP消息工厂
            MessageFactory messageFactory = MessageFactory.newInstance();
            SOAPMessage message = messageFactory.createMessage();
            
            // 创建SOAP消息的主体部分
            SOAPPart soapPart = message.getSOAPPart();
            SOAPEnvelope envelope = soapPart.getEnvelope();
            SOAPBody body = envelope.getBody();
            
            // 创建SOAP消息的操作元素
            QName operationQName = new QName("http://ws.dc.com", "ckts_bgdInfo");
            SOAPElement operationElement = body.addChildElement(operationQName);
            
            // 创建SOAP消息的xml元素
            QName xmlQName = new QName("http://ws.dc.com", "xml");
            SOAPElement xmlElement = operationElement.addChildElement(xmlQName);
            xmlElement.addTextNode("报文");
            
            // 设置SOAP消息的属性
            message.saveChanges();
            
            // 发送SOAP请求并获取响应
            SOAPMessage response = connection.call(message, "SOAP服务的URL");
            
            // 处理SOAP响应
            // ...
            
            // 关闭SOAP连接
            connection.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

在上述代码中，你需要将“SOAP服务的URL”替换为实际的 SOAP 服务的 URL。在handleResponse方法中，你可以编写处理 SOAP 响应的逻辑。
