Call SOAP service asynchronously using Spring - spring

Question

I've to call a SOAP web service asynchronously. Currently, I'm calling it in a synchronous way using Spring webservicetemplate.
Current config is like:
<bean id="interceptedHttpClientBuilder" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="httpClientBuilder" />
<property name="targetMethod" value="addInterceptorFirst"> </property>
<property name="arguments">
<list>
<bean class="org.springframework.ws.transport.http.HttpComponentsMessageSender.RemoveSoapHeadersInterceptor"/>
</list>
</property>
</bean>
<bean id="requestConfigBuilder" class="org.apache.http.client.config.RequestConfig" factory-method="custom">
<property name="socketTimeout" value="120000" />
</bean>
<bean id="requestConfig" factory-bean="requestConfigBuilder" factory-method="build" />
<bean id="httpClient" factory-bean="httpClientBuilder" factory-method="build" />
<bean id="httpClientBuilder" class="org.apache.http.impl.client.HttpClientBuilder" factory-method="create">
<property name="defaultRequestConfig" ref="requestConfig" />
</bean>
<bean id="messageSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender">
<constructor-arg ref="httpClient"></constructor-arg>
</bean>
<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="packagesToScan">
<list><value>...</value></list>
</property>
</bean>
<bean id="wsClientSecurityInterceptor"
class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor">
<property name="securementActions" value="UsernameToken" />
<property name="securementUsername"><value>${username}</value></property>
<property name="securementPassword"><value>${password}</value></property>
<property name="securementPasswordType" value="PasswordText" />
</bean>
<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
<property name="marshaller" ref="jaxb2Marshaller"></property>
<property name="unmarshaller" ref="jaxb2Marshaller"></property>
<property name="defaultUri"><value>${ws.url}</value></property>
<property name="interceptors">
<list>
<ref local="wsClientSecurityInterceptor"/>
</list>
</property>
<property name="messageSender" ref="messageSender"></property>
</bean>
Java call looks like:
MyResponse response = (MyResponse) webServiceTemplate.marshalSendAndReceive(req, new WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) {
((SoapMessage) message).setSoapAction("test");
}
});
May I know how can I change it to call the service asynchronously? Or Do I need to use something else in spring to achieve this?

Not sure why you use spring-integration tag in your question, but if we are here, please, definitely take a look into the #MessagingGateway with the Future<> as a return type: https://docs.spring.io/spring-integration/docs/5.0.1.RELEASE/reference/html/messaging-endpoints-chapter.html#async-gateway
The SOAP WebService can be called via Spring Integration <int-ws:outbound-gateway>: https://docs.spring.io/spring-integration/docs/5.0.1.RELEASE/reference/html/ws.html
The samples are here: https://github.com/spring-projects/spring-integration-samples
To be more clear the code might looks like this:
<int:gateway id="mathService"
service-interface="org.springframework.integration.samples.async.gateway.MathServiceGateway"
default-request-channel="requestChannel"
async-executor="executor"/>
Where that MathServiceGateway is like this:
public interface MathServiceGateway {
Future<Integer> multiplyByTwo(int i);
}
The WS call is simple as well:
<int-ws:outbound-gateway request-channel="requestChannel" uri="http://www.w3schools.com/xml/tempconvert.asmx"/>
