I have WSDL with me .eg: /sample/hello?wsdl . I want to invoke the service the webservice by configuring in Spring-ws. I passed this wsdl as parameter to tags in springconfig.xml. Can anyone please tell me how to consume this webservice in Spring-ws.
In the IDE I can generate the required code for the webservice call using the provided 'generate code: web service invoke operation' feature. This has added a @WebServiceRef(wsdlLocation = "WEB-INF/wsdl/servicename. wsdl") and some code to create a port and call the target webservice operation.
Steps to Consume a SOAP service : Create spring boot project and Get the WSDL from the provider . Convert the WSDL to Stub. Understand the request ,response and the types ,operations using any tool like SOAP UI. Form the request object by mapping data and call the soap uri with marshal the java objects as XML.
add the following dependencies to the pom file:
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-ws-core</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.2.5</version>

For example, if your SOAP request XML looked like
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xxx="http://yourcomapny.com">
<soapenv:Header/>
<soapenv:Body>
<xxx:InputParameters>
<xxx:paramONE>1</xxx:paramONE>
</xxx:InputParameters>
</soapenv:Body>
</soapenv:Envelope>
and your SOAP response XML looked like:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Header>
...
</env:Header>
<env:Body>
<xxx:OutputParameters xmlns:xxx="http://yourcompany.com">
<xxx:paramONE>0</xxx:paramONE>
</xxx:OutputParameters>
</env:Body>
</env:Envelope>
the corresponding classes (under the package you specified in the marshaller bean: com.yourcompany.model) would be respectively:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = { "paramONE" })
@XmlRootElement(name = "InputParameters", namespace = "http://yourcompany.com")
public class InputParameters {
@XmlElement(required = true, namespace = "http://yourcompany.com")
private String paramONE;
public String getParamONE() {
return paramONE;
}
public void setParamONE(String paramONE) {
this.paramONE = paramONE;
}
}
and
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = { "paramONE" })
@XmlRootElement(name = "OutputParameters", namespace = "http://yourcompany.com")
public class OutputParameters {
@XmlElement(required = true, namespace = "http://yourcompany.com")
private BigDecimal paramONE;
public BigDecimal getParamONE() {
return this.paramONE;
}
public void setParamONE(BigDecimal paramONE) {
this.paramONE= paramONE;
}
}
@XmlRegistry
public class ObjectFactory {
public ObjectFactory() {
}
public InputParameters createYourRequest() {
return new InputParameters();
}
public OutputParameters createYourResponse() {
return new OutputParameters();
}
}
Interface:
public interface YourService {
BigDecimal getValue(String paramOne);
}
Implementation
@Component("yourServiceClient")
public class YourServiceClient implements YourService {
private static final ObjectFactory WS_CLIENT_FACTORY = new ObjectFactory();
private WebServiceTemplate webServiceTemplate;
@Autowired
public YourServiceClient(WebServiceTemplate webServiceTemplate) {
this.webServiceTemplate = webServiceTemplate;
}
@Override
public BigDecimal getValue(String paramOne) {
InputParameters request = WS_CLIENT_FACTORY
.createYourRequest();
request.setParamONE(paramOne);
OutputParameters response = (OutputParameters) webServiceTemplate
.marshalSendAndReceive(request);
return response.getParamONE();
}
}
@Taoufik Mohdit answer is complete!!
To build the input and output objects you can use Webservice-Client: Common approach with Spring WS, JAXB and just one WSDL file? to some how build these objects automatically
