The client has to honor the format that we declared in the XSD document.
Let's map this document to a Subscription Request class: Subscription Request For every request sent by the client, we send a response.
Next step is defining the search criteria object, I am wrapping the search criteria into a seperate object so that in future, we can extend the search criteria by adding more elements like author, subject.
Here the xsd definition of the search criteriaobject with two fields title and published date.
When using contract-first, you start with the WSDL contract, and use Java to implement said contract. Our business partner has clients that needs to subscribe with our magazine.
Source: Spring WS Reference 2.0For an in-depth look of Spring WS, I suggest my readers to visit the Spring WS Reference 2.0 and the Spring WS API 2.0.0. To expose this feature, we decided to use a web service.
for a skeleton application, you can just run this maven archetype to quickly start with,mvn archetype:create -Darchetype Group Id=org.\-Darchetype Artifact Id=spring-ws-archetype \-Darchetype Version=1.5.4 \-Dgroup Id=\-Dartifact Id=spring-ws-test Or you can just add the spring nature to your existing web application by configuring the shown in the next step.
Here is the file structure I am using for this simple demo.2. Spring strongly supports only contract first web services for several reasons like Fragility, performance, re usability and versioning.This is self step is creating the JAXB objects for your xsd elements using xjc compiler. (My Intellij Idea supports generating JAXB objects directly from xsd).(Posting all the code is not practical, So I am moving here ahead posting the important parts)Here is the endpointnow the last and more important step, putting all the things together to deploy the service,configuring the First and the most important point here is I am autowiring the endpoint by using the annotation @Endpoint.you can either craft the JAXB objects by hand or justuse the xjc compiler. So in the context.xml, we are defining the wsdl to be exposed as a bean using the class org.wsdl.wsdl11. I am specifying the JAXBMarshaller and injecting all the jaxb classes.You can find more information visit this link So lets start first by developing our XSD....This is a plain regular xsd where we will define all our xml elements going to create our wsdl file.Spring Web Services aims to facilitate contract-first SOAP service development, allowing for the creation of flexible web services using one of the many ways to manipulate XML payloads.
