Restful JAX-RS服务器错误

Question

• 泽西-客户端
• 泽西-普通
• jersey-container-servlet
• jersey-container-servlet-core
• 泽西-服务器

如果我这样做，我总是得到以下异常：

java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

经过一些研究，我发现我应该添加jersey-servlet-1.12.jar，而不是从上面发布的下载源添加jar。所以我做了。我将其添加到web.xml中

<servlet>
    <servlet-name>JAX-RS Servlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>JAX-RS Servlet</servlet-name>
    <url-pattern>/jaxrs/*</url-pattern>
</servlet-mapping>

import java.util.List;

import javax.persistence.EntityManager;

import javax.persistence.Persistence;
import javax.persistence.TypedQuery;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import de.hof.university.spj.model.Movie;

@Path("/test")
public class Test {

    @GET
    @Produces("application/json; charset=UTF-8")
    public List<Movie> getMovieList() {
        EntityManagerFactory factory = Persistence.createEntityManagerFactory("SPJUnit");
        EntityManager em = factory.createEntityManager();

        TypedQuery<Movie> query = em.createQuery("Select m FROM Movie m WHERE m.movieID = 4204", Movie.class);

        return query.getResultList();
    }
}

HTTP Status 500 - Internal Server Error. The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.
