How to make spring soap web-service(JAX-WS)

step-1:

create xml schema please make sure Request/Response element must be named in following format.
{operation-name}Request and {operation-name}Response
Example: getCountryRequest and getCountryResponse ...findCountryRequest and findCountryResponse.

you can use eclipse design view to create xsd file.

Step-2

create spring boot with dependencies spring-boot-starter-web-services and wsdl4j and configure maven-plugin to generate jaxb classes using maven.

Example:

dependency example

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-web-services</artifactId>
	</dependency>
	<dependency>
		<groupId>wsdl4j</groupId>
		<artifactId>wsdl4j</artifactId>
	</dependency>

plugin example

	<plugin>
			<groupId>org.codehaus.mojo</groupId>
			<artifactId>jaxb2-maven-plugin</artifactId>
			<version>1.6</version>
			<executions>
				<execution>
					<id>xjc</id>
					<goals>
						<goal>xjc</goal>
					</goals>
				</execution>
			</executions>
			<configuration>
				<schemaDirectory>${project.basedir}/src/main/resources/com/xsd</schemaDirectory>
				<outputDirectory>${project.basedir}/src/main/java</outputDirectory>
				<clearOutputDir>false</clearOutputDir>
			</configuration>
		</plugin>

step-3

create configuration class in spring boot application and added following 3 beans into this class.

1-ServletRegistrationBean -- This is used to provide url mapping for your soap webservice
2-DefaultWsdl11Definition --This is used to generated runtime WSDL with help of bean called XsdSchema
3-XsdSchema --This bean is an input for DefaultWsdl11Definition

Example:

@Bean
	public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
		MessageDispatcherServlet servlet = new MessageDispatcherServlet();
		servlet.setApplicationContext(applicationContext);
		servlet.setTransformWsdlLocations(true);
		return new ServletRegistrationBean(servlet, "/ws/services/*");
	}

@Bean(name = "students")
public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema countriesSchema) {
	DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
	wsdl11Definition.setPortTypeName("StudentPort");
	wsdl11Definition.setLocationUri("/ws/services/mystudent");
	wsdl11Definition.setTargetNamespace("http://www.example.org/demo/");
	wsdl11Definition.setSchema(countriesSchema);
	Properties props = new Properties();
	//way to add soapAction uri
	props.put("getStudent", "http://www.example.org/demo/getStudentRequest");
	props.put("findCountry", "http://www.example.org/demo/findCountryRequest");
	wsdl11Definition.setSoapActions(props);
	
	return wsdl11Definition;
}

@Bean
public XsdSchema countriesSchema() {
	return new SimpleXsdSchema(new ClassPathResource("/com/xsd/demo.xsd"));
}

notes:

wsdl url will be "<ip:port>/<ServletRegistrationBean-urlmapping>/<DefaultWsdl11Definition-bean-name><.wsdl>"
example: localhost:8080/ws/services/students.wsdl
please ,makesure setLocationUri  must contain wsdl-urlmapping as prefix(in this case-/ws/services/)
setLocationUri and soapaction we use client side to call webservice.
spring webservice xsd definition must be in request/resposne format else will not work
example- getCountryRequest and getCountryResponse.in this case  <operation-name>Request/Response
here operation name will be getCountry

step-4

create endpoint class to make responsive service.

class must be annotated with @Endpoint and method must be annotated with
@PayloadRoot(namespace = NAMESPACE_URI, localPart = "getStudentRequest")
@ResponsePayload
and method-argument(request) must be annotated with @RequestPayload

NAMESPACE_URI is a target namespace value which is used in xsd file.
localPart is a request element name of xsd file.
soapAction={namespace}/{localpart}

Example:

@Endpoint
public class WebServiceEndpoint {
	private static final String NAMESPACE_URI = "http://www.example.org/demo/";	
//localPart must be xsd request element name.
@PayloadRoot(namespace = NAMESPACE_URI, localPart = "getStudentRequest")
@ResponsePayload
public GetStudentResponse findStudent(@RequestPayload GetStudentRequest request,MessageContext messageContext) {
	GetStudentResponse ret = new GetStudentResponse();
	ret.setId(101);
	ret.setName("Amir");
	ret.setAge(32);
	return ret;
}
}
