You have a couple options:
1) If you want to leave your Spring context as is and change the address
programmatically at runtime:
You can set a standard property in the request context. Here is an example
of how to do this programmatically.
BindingProvider bp = (BindingProvider)port;
Map<String, Object> context = bp.getRequestContext();
Object oldAddress = context.get(BindingProvider.ENDPOINT_ADDRESS_PROPERTY);
context.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
newAddress);
When doing this, you should be aware of multi-threaded access to a client
proxy. See the CXF FAQ (Are JAX-WS client proxies thread safe?)[1]
2) If you are willing/able to provide WSDL URLs and use the JAX-WS APIs, you
can write portable code that will create a client proxy wired to an endpoint
of your choosing. You can use the "createdFromAPI" (Configuring a Spring
Client (Option 1)) [2] attribute in your Spring context file to still allow
Spring based configuration of the programmatically constructed client proxy.
I think that wildcards are also supported here so you should be able to
configure a number of clients using a single <jaxws:client> entry in your
Spring context. This approach will get more complex if the endpoint
namespaces/local names vary greatly between the endpoints you are trying to
interact with.
3) Use org.apache.cxf.jaxws.JaxWsProxyFactoryBean programmatically as shown
in the Spring configuration of Configuring a Spring Client (Option 2) [2].
This lets you set the interface and address and create new client proxy
instances at will. You may even want to configure a single instance of this
factory with most properties already set in Spring and then inject it into
your code where you can change the address and construct a new client proxy
at will (providing for synchronized access to the factory bean of course).
You can also cache the client proxies to avoid the expense of re-creating
them repeatedly.

Subject: How to provide server address to the Spring-configured Apache
CXF-based web service client?
Hi,
I'm experimenting with Apache CXF and have a question about the client part.
Below is my current Spring configuration of the WS client of some
com.example.customerservice.service.CustomerService:
<jaxws:client
name="com.example.customerservice.service.CustomerServiceClient"
serviceName="customer:CustomerServiceService"
endpointName="customer:CustomerServiceEndpoint"
address="http://localhost:8080/CustomerServicePort";
serviceClass="com.example.customerservice.service.CustomerService">
<jaxws:features>
<bean class="org.apache.cxf.feature.LoggingFeature" />
</jaxws:features>
</jaxws:client>
As you see, the address attribute is configured statically. This is
not suitable for me because I don't know the server URL in advance.
Moreover, in certain scenarios I'd like to use this client for
different services which have different addresses.
Therefore static configuration of the server address in Spring is not
appropriate. So my question is - how can I make it dynamic?
At the moment my solution is to set a system property - something like
baseUrl and inject it into the Spring config using the property
placeholder configurer.
Another possibility would be to simply construct the client manually
which I don't really like either.
But I believe I'm really missing something. Maybe there is a
possibility of something like
clientFactory.createClientFor("http://myserver:8080";)?
Thank you for the answers!
Bye,
