Avoid wrapping the object type name from input/output JSON (CXF Web Service)

Question

I have a CXF Web Service something like this:

@Service("MyWebService")
public class MyWebService implements IMyWebService {    
    @Autowired
    private IMyService MyService;

    public ResponseObject doSomething(RequestObject requestObject) {
        ResponseObject responseObject = new ResponseObject;     
        .
        // do something....
        .
        .        
        return responseObject;
    }
}

that expects an input JSON, say something like this:

{ "requestObject" : { "amount" : 12.50, "userName" : "abcd123" } }

and produces an output JSON something like this:

{ "responseObject" : { "success" : "true", "errorCode" : 0 } }

Is there a way to configure CXF such that it accepts the input JSON in the following format:

{ "amount" : 12.50, "userName" : "abcd123" }

I need to strip out the object type name 'requestObject' / 'responseObject' in the input and output JSON. Is that even possible?

Your help appreciated!

Answer 1

If you are using maven, the JSONProvider class is here:

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-rs-extension-providers</artifactId>
    <version>2.7.5</version>
</dependency>

You might need another json provider properties to achieve your goals:

<jaxrs:providers>
     <bean class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
           <property name="dropRootElement" value="true"/>
           <property name="dropCollectionWrapperElement" value="true"/>
           <property name="serializeAsArray" value="true"/>
           <property name="supportUnwrapped" value="true"/>
     </bean>
</jaxrs:providers>

If you are configuring the json provider through springs xml config file (like applicationContext.xml), then just add the below configuration it will work.

<jaxrs:providers>
            <bean class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
                <property name="dropRootElement" value="true" />
                <property name="supportUnwrapped" value="true" />
            </bean>
</jaxrs:providers>

The dropRootElement tells the json provider to drop the root element. Refer to this JSON Support for more configuration and understanding.
