48. Calling Web Services with WebServiceTemplate

If you need to call remote Web services from your application, you can use the WebServiceTemplate class. Since WebServiceTemplate instances often need to be customized before being used, Spring Boot does not provide any single auto-configured WebServiceTemplate bean. It does, however, auto-configure a WebServiceTemplateBuilder, which can be used to create WebServiceTemplate instances when needed.

The following code shows a typical example:

@Service
public class MyService {

	private final WebServiceTemplate webServiceTemplate;

	public MyService(WebServiceTemplateBuilder webServiceTemplateBuilder) {
		this.webServiceTemplate = webServiceTemplateBuilder.build();
	}

	public DetailsResp someWsCall(DetailsReq detailsReq) {
		 return (DetailsResp) this.webServiceTemplate.marshalSendAndReceive(detailsReq, new SoapActionCallback(ACTION));

	}

}

By default, WebServiceTemplateBuilder detects a suitable HTTP-based WebServiceMessageSender using the available HTTP client libraries on the classpath. You can also customize read and connection timeouts as follows:

@Bean
public WebServiceTemplate webServiceTemplate(WebServiceTemplateBuilder builder) {
	return builder.messageSenders(new HttpWebServiceMessageSenderBuilder()
			.setConnectTimeout(5000).setReadTimeout(2000).build()).build();
}
