How to consume third party WSDL services in Spring MVC - spring

Question

I wrote some services (used by an Android app) which takes a request and sends th response in json. Now I have a scenario where I have to consume a third party web service, through a provided WSDL file. I don't know how to do this, can anyone help?
This is my dispatcher-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans ">
<context:property-placeholder location="classpath:jdbc.properties" />
<context:component-scan base-package="com.srihari" />
<tx:annotation-driven transaction-manager="hibernateTransactionManager" />
<mvc:annotation-driven />
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${database.driver}" />
<property name="url" value="${database.url}" />
<property name="username" value="${database.user}" />
<property name="password" value="${database.password}" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="annotatedClasses">
<list>
<value>com.srihari.model.User</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
<bean id="hibernateTransactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
//This is used to convert my requests and responses into json automatically
<bean id="jacksonMessageChanger" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes" value="application/json"/>
</bean>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<util:list id="beanList">
<ref bean="jacksonMessageChanger"/>
</util:list>
</property>
</bean>
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="json" value="application/json"/>
<entry key="html" value="text/html"></entry>
<entry key="xml" value="application/xml"></entry>
</map>
</property>
</bean>
</beans>
This is my simple controller: These services are working fine
#Controller
#RequestMapping("/home")
public class UserController {
#RequestMapping(value="/getallusers",method = RequestMethod.GET)
public #ResponseBody List<User> getallusers()
{
List<User> allUsersDetails =userServices.getAllUsers();
return allUsersDetails;
}
}
This is the WSDL file provided by the third party
POST /someservices/otherService.asmx HTTP/1.1
Host: sriharicorp.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/CreateCard"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<UserCredentials xmlns="http://tempuri.org/">
<Password>string</Password>
<Username>string</Username>
</UserCredentials>
</soap:Header>
<soap:Body>
Example String Request
<CreateCard xmlns="http://tempuri.org/">
<request>
<DePpAcctCreationDate>string</DePpAcctCreationDate>
<DePpAcctCreationTime>string</DePpAcctCreationTime>
//Some other fields also
</request>
</CreateCard>
</soap:Body>
</soap:Envelope>
Example String Response
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<CreateCardResponse xmlns="http://tempuri.org/">
<CreateCardResult>
<RequestType>string</RequestType>
<ProductType>string</ProductType>
<ResponseCode>string</ResponseCode>
<ReasonDescription>string</ReasonDescription>
</CreateCardResult>
</CreateCardResponse>
</soap:Body>
</soap:Envelope>

Answer 1

Finally I'm able to access Third services.
This is my method to access service
public void createSoapActionCallBack(ValidateCardRequest validateCardRequest) {
//This is used to send header message
SoapActionCallback actionCallBack=new SoapActionCallback(soapAction);
try{
actionCallBack = new SoapActionCallback(ResponseConstants.SOAPACTION_DEFAULT_URL) {
public void doWithMessage(WebServiceMessage msg) {
SoapMessage smsg = (SoapMessage)msg;
SoapHeader soapHeader = smsg.getSoapHeader();
try{
//To send header message
StringSource headerSource = new StringSource("<UserCredentials xmlns='URL'>\n" +
"<userid>"+"ABCD"+"</userid>\n" +
"<password>"+"ABCD"+"</password>\n" +
"</UserCredentials>");
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(headerSource, soapHeader.getResult());
smsg.setSoapAction(soapAction);
}catch(Exception e)
{
e.printStackTrace();
}
}
};
validateCardResponse = (FVValidateCardResponse) webServiceTemplate.marshalSendAndReceive(URL, validateCardRequest, actionCallBack);
} catch (Exception e) {
e.printStackTrace();
}
}
This is my configuration xml file:
<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
<property name="soapVersion">
<util:constant static-field="org.springframework.ws.soap.SoapVersion.SOAP_12"/>
</property>
</bean>
<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<!-- If we want to use contextPath then we mush create ObjectFactory class in the described Package-->
<!-- <property name="contextPath" value="com.waleteros.firstviewmodel" /> -->
<property name="classesToBeBound">
<list>
<value>com.waleteros.firstviewmodel.FVValidateCardRequest</value>
<value>com.waleteros.firstviewmodel.FVValidateCardResponse</value>
</list>
</property>
</bean>
<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
<constructor-arg ref="messageFactory" />
<property name="marshaller" ref="marshaller"></property>
<property name="unmarshaller" ref="marshaller"></property>
<property name="messageSender">
<bean class="org.springframework.ws.transport.http.HttpComponentsMessageSender"/>
</property>
<!-- <property name="defaultUri" value="https://www.firstviewcorp.com/dbbapplications/ServicesSS/Selfservice.asmx?wsdl"/> -->
</bean>
Create pojo's according to your xmls
Here is example
#XmlAccessorType(XmlAccessType.FIELD)
#XmlRootElement(name = "CardUpdateResponse",namespace="http://www.corecard.com/Prepaid")
public class FVCardUpdateResponse {
#XmlElement(name="CARDUPDATE_RET", namespace="http://www.corecard.com/Prepaid")
private CARDUPDATE_RET response;
//Getters and Setters
public static class CARDUPDATE_RET{
#XmlElement(name = "ACCOUNTNUMBER", namespace="http://www.corecard.com/Prepaid")
private String AccountNumber;
#XmlElement(name = "ResCode", namespace="http://www.corecard.com/Prepaid")
private String ResCode;
#XmlElement(name = "ResErrorCode", namespace="http://www.corecard.com/Prepaid")
private String ResErrorCode;
#XmlElement(name = "ResErrorMsg", namespace="http://www.corecard.com/Prepaid")
private String ResErrorMsg;
//Getters and Setters
}
}
