how can I get the response message from Axis2 in spring integration

问题

I need to integrate my webservice (Axis2) in spring integration: I have spring-axis2-message.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/integration"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:beans="http://www.springframework.org/schema/beans"
	xmlns:stream="http://www.springframework.org/schema/integration/stream"
	xmlns:ws="http://www.springframework.org/schema/integration/ws"
	xsi:schemaLocation="http://www.springframework.org/schema/beans

	<chain input-channel="messageChannelIN" output-channel="messageChannelOUT">
		<ws:header-enricher    >
			<ws:soap-action value="getMessageService"/>
		</ws:header-enricher>
		<ws:outbound-gateway uri="http://localhost:8080/axis2-webservice/services/wservices?wsdl" reply-channel="messageChannelOUT"/>
	</chain>
	

	<!-- The response from the service is logged to the console. -->
	<stream:stdout-channel-adapter id="messageChannelOUT"  append-newline="true" />
	
</beans:beans>

And a TestAxis2.java

package org.neos.spring.test;

import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.integration.support.MessageBuilder;
import org.springframework.integration.support.channel.BeanFactoryChannelResolver;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageChannel;
import org.springframework.messaging.core.DestinationResolver;


public class TestAxis2 {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
				"/META-INF/spring/integration/spring-axis2-message.xml");
		DestinationResolver<MessageChannel> channelResolver = new BeanFactoryChannelResolver(context);

		String requestXml = 
				"<getMessageService xmlns=\"http://service.ws.axis2.neos.org\">" + 
						"<name>HUGO</name>"
				+ "</getMessageService>";

		// Create the Message object
		Message<String> message = MessageBuilder.withPayload(requestXml).build();

		// Send the Message to the handler's input channel
		MessageChannel channel = channelResolver.resolveDestination("messageChannelIN");
		channel.send(message);
		
	}

}

The program run very well and I can see in the console the next response:

<?xml version="1.0" encoding="UTF-8"?><ns:getMessageServiceResponse xmlns:ns="http://service.ws.axis2.neos.org"><ns:return>HELLO HUGO!, WELCOME TO WEBSERVICE AXIS1 hola</ns:return></ns:getMessageServiceResponse>

My question is how Can I manipulate/How can get the response in Java program because I need the response. I tried to do a lot of things but unfortunately did not work anything I only can see the response in the console but I need to manipulate the response.

I do not how can I access this configuration or if I need to configurate other things.

access<stream:stdout-channel-adapter id="messageChannelOUT"  append-newline="true" />

Can Anyone help me please?

回答1:

Use a Messaging Gateway.

public interface Gateway

    String sendAndReceive(String out);

}

<int:gateway service-interface="foo.Gateway" 
     default-request-channel="messageChannelIN" />

Remove the output-channel from the chain

The reply will be returned to the caller via the gateway

Gatweway gw = context.getBean(Gateway.class);
...
String reply = gw.sendAndReceive(requestXml);

This has the added bonus of not exposing your application to the messaging infrastructure.

It's working my program right now!!. Thanks for your help Gary Russell!!! your comments were very useful.

The final code was:

xml configuration

........
<chain input-channel="messageChannelIN">
    <ws:header-enricher>
        <ws:soap-action value="getMessageService"/>
    </ws:header-enricher>
    <ws:outbound-gateway uri="http://localhost:8080/axis2-webservice/services/wservices?wsdl" />
</chain>

<gateway id="messageChannelOUT" service-interface="org.neos.spring.ws.service.GatewayAxis" default-request-channel="messageChannelIN"/>

Java Code:

public interface GatewayAxis {
  @Gateway
  String sendAndReceive(String out);}

TestAxis2

public static void main(String[] args) {
    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
            "/META-INF/spring/integration/spring-axis2-message.xml");

    GatewayAxis gateway = context.getBean(GatewayAxis.class);

    String requestXml = 
            "<getMessageService xmlns=\"http://service.ws.axis2.neos.org\">" + 
                    "<name>HUGO</name>"
            + "</getMessageService>";
    String reply = gateway.sendAndReceive(requestXml);
    System.out.println(reply);

}
