Spring Soap client

• add dependecy spring-boot-starter-web-services
• add maven plugin to generate classes from wsdl
• add client
• add client and marshaller as spring bean
• Wrap Request in JAXBElement if error "unable to marshal type "xyz" as an element because it is missing an @XmlRootElement annotation" happended

add dependecy spring-boot-starter-web-services

Add to pom:

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

add maven plugin to generate classes from wsdl

Add to pom:

   <!-- SOAP client-->

   ....

            <plugin>
                <groupId>org.jvnet.jaxb</groupId>
                <artifactId>jaxb-maven-plugin</artifactId>
                <version>4.0.8</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <schemaLanguage>WSDL</schemaLanguage>
                    <generateDirectory>${project.basedir}/src/main/java</generateDirectory>
                    <!-- also set in spring config -->
                    <generatePackage>de.weyrich.soapclient.gen</generatePackage>
                    <schemaDirectory>${project.basedir}/src/main/resources</schemaDirectory>
                    <schemaIncludes>
                         <include>meine.wsdl</include>
                    </schemaIncludes>
                </configuration>
            </plugin>

        </plugins>
    </build>
</project>

add client

package de.weyrich;

import de.weyrich.soapclient.gen.BeispielRequest;
import de.weyrich.soapclient.gen.BesipielResponse;
import jakarta.xml.bind.JAXBElement;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;

public class SoapClientExamle extends WebServiceGatewaySupport {

    public BeispielRequestResponse callBeispielRequest(String typeName) {
        BeispielRequestRequest request = new BeispielRequestRequest();
        request.setTypeName(typeName);
        return (BeispielRequestResponse) getWebServiceTemplate().marshalSendAndReceive(request);
    }
}

see last example if this thtows a @XMLRootElement error or an error that JAXB cannot find BeispielRequest.

add client and marshaller as spring bean

package de.weyrich;

import de.weyrich.SoapClientExamle;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;

@Configuration
public class SoapClientConfig {

    @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        // must match plugin in pom
        marshaller.setContextPath("de.weyrich.soapclient.gen");
        return marshaller;
    }
    @Bean
    public SoapClientExamle SoapClientExamle(Jaxb2Marshaller marshaller) {
        SoapClientExamle client = new SoapClientExamle();
        client.setDefaultUri("https://example.de/soapservice");
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);
        return client;
    }
}

Wrap Request in JAXBElement if error "unable to marshal type "xyz" as an element because it is missing an @XmlRootElement annotation" happended

Use ObjectFactory to wrap request in JAXBElement. Needs to be done when @XmlRootElement is missing in generated classes which might happen because of leagcy WSDL stuff.

```java package de.weyrich;

import de.weyrich.soapclient.gen.BeispielRequest; import de.weyrich.soapclient.gen.BesipielResponse; import de.weyrich.soapclient.gen.ObjectFactory; import jakarta.xml.bind.JAXBElement; import org.springframework.ws.client.core.support.WebServiceGatewaySupport;

public class SoapClientExamle extends WebServiceGatewaySupport {

public BeispielRequestResponse callBeispielRequest(String typeName) {
    BeispielRequestRequest request = new BeispielRequestRequest();
    request.setTypeName(typeName);
    JAXBElement<BeispielRequestRequest> requestWrapped = new ObjectFactory().createBeispielRequestRequest(request);
    return (BeispielRequestResponse) getWebServiceTemplate().marshalSendAndReceive(requestWrapped);
}

}
