ServiceContractResolver
interface. You also need to register your custom resolver with the bus.

org.apache.cxf.endpoint.ServiceContractResolver
interface. As shown in Example 29.3, “ServiceContractResolver
Interface”, this interface has a single method, getContractLocation()
, that needs to be implemented. getContractLocation()
takes the QName of a service and returns the URI for the service's WSDL contract.
Example 29.3. ServiceContractResolver
Interface
public interface ServiceContractResolver { URI getContractLocation(QName qname); }
public interface ServiceContractResolver
{
URI getContractLocation(QName qname);
}

org.apache.cxf.endpoint.ServiceContractResolverRegistry
interface. However, you do not need to implement your own registry. Apache CXF provides a default implementation in the org.apache.cxf.endpoint.ServiceContractResolverRegistryImpl
class.
- Get a reference to the default bus object.
- Get the service contract registry from the bus using the bus'
getExtension()
method. - Create an instance of your contract resolver.
- Register your contract resolver with the registry using the registry's
register()
method.
Example 29.4. Registering a Contract Resolver
Registering a contract resolver using configuration Copia collegamentoCollegamento copiato negli appunti!
- Add an
init()
method to your contract resolver implementation. - Add logic to your
init()
method that registers the contract resolver with the contract resolver registry as shown in Example 29.4, “Registering a Contract Resolver”. - Decorate the
init()
method with the@PostConstruct
annotation.
Example 29.5. Service Contract Resolver that can be Registered Using Configuration
bean
element to the client's configuration. The bean
element's class
attribute is the name of the class implementing the contract resolver.
org.apache.cxf.demos.myContractResolver
class.
