Hello i have a problem with apache cxf and a rest service (with jax-rs, and spring).
I'm trying to publish a rest service : userService
The error is :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Invocation of init method failed; nested exception is org.apache.cxf.service.factory.ServiceConstructionException

The applicationContext-cxf.xml :
<import resource="classpath:META-INF/cxf/cxf.xml" />
<jaxrs:server id="userService" address="/">
<jaxrs:serviceBeans>
<ref bean="userService" />
</jaxrs:serviceBeans>
</jaxrs:server>
The service interface :
@Path("v1")
public interface UserService {
@GET
@Path("user")
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public User getUser();
}
The service implementation :
@Service("userService")
public class UserServiceImpl implements UserService {
public User getUser() {
User u = new User();
u.setFirstName("plop");
u.setLastName("plop");
u.setEmail("[email protected]");
u.setUuid("1");
return u;
}
}
Thanks a lot for the help ! This problem kills me !
The @Provider annotation is used for anything that is of interest to the JAX-RS runtime, such as MessageBodyReader and MessageBodyWriter . For HTTP requests, the MessageBodyReader is used to map an HTTP request entity body to method parameters.
It is a standard that makes it simple to make a RESTful service help that can be conveyed to any Java application server. JAX-RS is a piece of Java EE, and when it is utilized with other Java EE advances it turns out to be considerably simpler to make your RESTful help.
INTRODUCTION. This article introduces you to the Java API for RESTful Web Services (JAX-RS), which resulted from Java Specification Request (JSR) 311 and is a component of the Java Enterprise Edition Platform (Java EE 6).
I think your problem is here:
<jaxrs:server id="userService" address="/">
<jaxrs:serviceBeans>
<ref bean="userService" />
</jaxrs:serviceBeans>
</jaxrs:server>
You're creating a bean named "userService" referencing a bean named "userService". Maybe change the bean name of the jaxrs:server endpoint to something different from "userService"?
