We will use Maven and Spring WS to create simple Web Service client.

  • Configure Maven dependencies:

    pom.xml

    <project...> <dependencies> <!-- JAXB dependencies --> <dependency> <groupId>javax.xml.bind</groupId> <artifactId>jaxb-api</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>com.sun.xml.bind</groupId> <artifactId>jaxb-impl</artifactId> <version>2.2.2</version> </dependency> <!-- Spring WS dependencies --> <dependency> <groupId>org.springframework.ws</groupId> <artifactId>spring-ws-core</artifactId> <version>2.0.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.ws</groupId> <artifactId>spring-ws-security</artifactId> <version>2.0.1.RELEASE</version> </dependency> <dependency> <groupId>org.apache.ws.commons.schema</groupId> <artifactId>XmlSchema</artifactId> <version>1.4.7</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> </dependencies> </project>



  • Download WS XSD schemas to project directory src/main/resources/schema

  • Configure JAXB to generate classes:

    pom.xml

    <project...> <build> <plugins> <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.7.5</version> <executions> <execution> <id>jaxb-ws-pvplanner</id> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <schemaDirectory>src/main/resources/schema</schemaDirectory> </configuration> </plugin> </plugins> </build> <project>



  • Define Spring WebServiceTemplate context:

    <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:oxm="http://www.springframework.org/schema/oxm" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- contextPath - package where to find request and response classes to marshall / unmarshal if request and response are in different packages, declare marshaller and unmarshaller separately --> <oxm:jaxb2-marshaller id="jaxb2marshaller" contextPath="eu.geomodel.schema.ws.pvplanner"/> <bean id="pvPlannerTemplate" class="org.springframework.ws.client.core.WebServiceTemplate" p:marshaller-ref="jaxb2marshaller" p:unmarshaller-ref="jaxb2marshaller" p:defaultUri="https://solargis.info/ws/soap/pvPlanner"> <!-- web service endpoint uri --> <property name="interceptors"> <list> <bean class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor" p:securementActions="Timestamp UsernameToken" p:securementUsername="demo" p:securementPassword="demo"/> </list> </property> </bean> </beans>



  • Define client Spring bean:

    // imports omitted public class PvPlannerWsClient { @Autowired @Qualifier("pvPlannerTemplate") WebServiceTemplate template; public CalculateResponse callPvPlanner(/*some args*/) { return (CalculateResponse) template.marshalSendAndReceive(prepareRequest(/*some args*/)); } private CalclulateRequest prepareRequest(/*some args*/) { // just sample request CalculateRequest request = new CalculateRequest(); Location location = new Location(); location.setLat(48.612590); // location of demo site location.setLng(20.827079); request.setLocation(location); PvSystem system = new PvSystem(); system.setInstalledPower(1); system.setModuleType(ModuleTypeEnum.C_SI); Settings settings = new Settings(); settings.setInverterEfficiency(97.5); settings.setDcLosses(5.5); settings.setAcLosses(1.5); settings.setAvailability(99); system.setSettings(settings); MountingFixedRoofMounted mounting = new MountingFixedRoofMounted(); mounting.setAzimuth(175); mounting.setInclination(45D); system.setMounting(mounting); request.setSystem(system); return request; } }
