AbstractMethodError：REST中的javax.ws.rs.core.UriBuilder.uri，EJB應用程序

Question

我對我的pom.xml文件有麻煩。我知道，關於這個問題有很多話題，但是他們中的任何一個都能解決我的問題。

@Path("/actors") 
public class MainController { 

    @EJB 
    private ActorDaoLocal actorDao; 

} 

@Local 
public interface ActorDaoLocal { 
    //some stuff here 
} 

@Stateless 
public class ActorDao implements ActorDaoLocal { 

    @PersistenceContext 
    private EntityManager em ; 
    //some stuff here 
} 

@ManagedBean(name = "ActorBean") 
@ApplicationScoped 
public class ActorBean { 

    @EJB 
    private ActorDaoLocal usersDao; 

} 

在我的應用程序，當我在ActorBean沒有註解如下：

@ManagedBean(name = "ActorBean") 
@ApplicationScoped 

actorDao是空的MainController

然而，當我加入這個註解和依賴它我正在獲取例外：

java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder; 
    at javax.ws.rs.core.UriBuilder.fromUri(UriBuilder.java:119) 
    at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:651) 
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) 

我的pom.xml：

請幫我解決這個問題，我在我的pom文件中找不到錯誤。

你在你的類路徑中包含javax.ws.rs.core.UriBuilder兩個JAX-RS 1.1的多依賴的工作：

<dependency> 
    <groupId>javax.ws.rs</groupId> 
    <artifactId>jsr311-api</artifactId> 
    <version>1.1.1</version> 
</dependency> 

---

<dependency> 
    <groupId>com.sun.jersey</groupId> 
    <artifactId>jersey-core</artifactId> 
    <version>1.18</version> 
</dependency> 

而且JAX-之一RS 2.0：

<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>7.0</version> 
</dependency> 

由於JAX-RS 2.0是從Java EE 7，可能需要降級javaee-api至6版本，使用這樣的：

<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>6.0</version> 
</dependency> 

另一種方法是升級澤西版本，像這樣的回答：AbstractMethodError using UriBuilder on JAX-RS

在運行時UriBuilder#uri(String)被調用，所以您需要驗證servlet容器中的依賴關係。
