Call SOAP service from java Spring boot

Call SOAP service from java Spring boot

I'll respond in English.

To call a SOAP (Simple Object Access Protocol) service from a Java-based application, you can use the org.springframework.ws module provided by Spring Boot. Here's an example of how to do it:

First, add the following dependencies to your pom.xml file (if you're using Maven):

org.springframework
spring-web-services
3.2.8.RELEASE

Next, create a Java class that will handle the SOAP request and response:

import org.springframework.ws.client.core.WebServiceTemplate;
import org.springframework.ws.soap.SOAPMessage;
public class SoapClient {
private final WebServiceTemplate webServiceTemplate;
public SoapClient() {
this.webServiceTemplate = new WebServiceTemplate();
}
public String callSoapService(String soapAction, String requestXml) throws Exception {
SOAPMessage soapMessage = createSoapMessage(soapAction, requestXml);
JAXBElement response = webServiceTemplate.marshalSendAndReceive(soapMessage);
SomeResponseClass responseObject = response.getValue();
return responseObject.toString();
}
private SOAPMessage createSoapMessage(String soapAction, String requestXml) throws Exception {
// Create a new SOAP message
SoapMessage soapMessage = new SoapMessage();
// Set the SOAP action
soapMessage.setSoapAction(soapAction);
// Add the request XML to the message body
soapMessage.getBody().addTextNode(requestXml);
return soapMessage;
}
}

In this example, we're creating a SoapClient class that has a method called callSoapService. This method takes three parameters: soapAction, which is the name of the SOAP action to call; requestXml, which is the XML request data; and returns the response from the SOAP service.

The createSoapMessage method creates a new SOAP message with the specified soap action and adds the request XML to the message body. The marshalSendAndReceive method is used to send the SOAP request to the server and receive the response.

To use this class, you'll need to create an instance of it and then call the callSoapService method:

SoapClient soapClient = new SoapClient();
String response = soapClient.callSoapService("someAction", "");

Make sure to replace "someAction" with the actual name of your SOAP action, and <requestXml> with the actual XML request data.

I hope this helps! Let me know if you have any further questions.

How to do a SOAP request in Java?

I'd be happy to help!

To make a SOAP (Simple Object Access Protocol) request in Java, you can use the Apache Axis library or another similar library like CXF or Metro. Here's an example using Axis2:

Step 1: Add dependencies

In your Java project, add the following dependencies to your pom.xml file (if you're using Maven):

org.apache.axis2
axis2
1.7.8
junit
junit
4.11
test

Step 2: Create a SOAP request

Create a new Java class that will handle the SOAP request. For example, let's call it SoapRequestHandler:

import org.apache.axis2.AxisFault;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.util.Loader;
import org.apache.axis2.xml.XMLInputStream;
public class SoapRequestHandler {
public String handleSoapRequest(String requestXml) throws AxisFault {
// Create an AxisConfiguration object
AxisConfiguration axisConfig = new AxisConfiguration();
// Set the XML parser
axisConfig.setProperty("axis2.xml.parser", "org.apache.xerces.parsers.SAXParser");
// Create a SOAP request handler
SoapRequestHandler soapRequestHandler = new SoapRequestHandler(axisConfig);
// Send the request
String responseXml = soapRequestHandler.sendRequest(requestXml);
return responseXml;
}
private static void sendRequest(SOAPMessage message, MessageContext ctx) {
try {
// Get the XML input stream
XMLInputStream xmlInput = (XMLInputStream) message.getXMLInputStream();
// Get the SOAP body
SOAPBody soapBody = (SOAPBody) xmlInput.nextElement();
// ... handle the request data here ...
// Create a response
SOAPMessage response = createResponse(soapBody);
// Send the response back to Axis
ctx.setSoapResponse(response);
} catch (AxisFault e) {
throw new AxisFault(e.getMessage());
}
}
private SOAPMessage createResponse(SOAPBody soapBody) {
// ... implement your logic here ...
return null;
}
}

Step 3: Make the request

Now, let's make a simple request to a SOAP service. For example, we'll send a getHelloWorld request:

public class Main {
public static void main(String[] args) {
try {
// Create a SoapRequestHandler instance
SoapRequestHandler soapRequestHandler = new SoapRequestHandler();
// Set the SOAP request XML
String requestXml = "<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope/">soap:Body</soap:Body></soap:Envelope>";
// Make the request
String responseXml = soapRequestHandler.handleSoapRequest(requestXml);
// Print the response XML
System.out.println(responseXml);
} catch (AxisFault e) {
System.out.println("Error: " + e.getMessage());
}
}
}

This code sends a SOAP request with the getHelloWorld method and prints the response.

Note that this is just a basic example. You'll likely need to add more functionality, error handling, and logging depending on your specific requirements.

That's it! I hope this helps you get started with making SOAP requests in Java.
