REST-Service mit jax-rs: BeanCreationException

Question

Hallo, ich habe ein Problem mit Apache CXF und einem Rest Service (mit Jax-Rs und Feder).

Ich versuche, einen Rest-Dienst zu veröffentlichen: Userservice

Der Fehler ist:

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

Die web.xml:

<display-name>CXF REST Example</display-name> 
<description>CXF REST Example</description> 

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/applicationContext-cxf.xml</param-value> 
</context-param> 

<listener> 
    <listener-class>

</servlet> 

<servlet-mapping> 
    <servlet-name>CXFServlet</servlet-name> 
    <url-pattern>/*</url-pattern> 
</servlet-mapping> 

Das application-cxf.xml:

<import resource="classpath:META-INF/cxf/cxf.xml" /> 

<jaxrs:server id="userService" address="/"> 
    <jaxrs:serviceBeans> 
     <ref bean="userService" /> 
    </jaxrs:serviceBeans> 
</jaxrs:server> 

Die Service-Schnittstelle:

@Path("v1") 
public interface UserService { 
    @GET 
    @Path("user") 
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON }) 
    public User getUser(); 
} 

Die Service-Implementierung:

@Service("userService") 
public class UserServiceImpl implements UserService { 

    public User getUser() { 
     User u = new User(); 
     u.setFirstName("plop"); 
     u.setLastName("plop"); 
     u.setEmail("plop@plop.com"); 
     u.setUuid("1"); 

     return u; 
    } 

} 

Vielen Dank für die Hilfe! Dieses Problem bringt mich um!

Answer 1

Ich denke, Ihr Problem hier ist:

<jaxrs:server id="userService" address="/"> 
    <jaxrs:serviceBeans> 
     <ref bean="userService" /> 
    </jaxrs:serviceBeans> 
</jaxrs:server> 

Sie eine Bohne "Userservice" Bezugnahme auf eine Bean mit dem Namen "Userservice" genannt zu schaffen. Vielleicht ändern Sie den Bean-Namen des jaxrs: server-Endpunkts in etwas anderes als "userService"?

Answer 2

Try this:

<jaxrs:server address="/"> 
<jaxrs:serviceBeans> 
<ref bean="userService" /> 
</jaxrs:serviceBeans> 
</jaxrs:server> 

Remove id-Attribut, Bohnen Namen mit Kleinbuchstaben beginnen sollte.
