Web サービスで問題が発生しています --- Web サービスから映画リストを取得しようとしていますが、常にこの厄介なエラーが発生します。
ここに私のモデルがあります:
package de.hawhof.dm.kino.model;
import java.io.Serializable;
import java.util.List;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Lob;
import javax.persistence.OneToMany;
import javax.xml.bind.annotation.XmlRootElement;
@Entity
@XmlRootElement(name="movie")
public class Movie implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
int movieid;
String name;
String releaseDate;
@Lob
String critic;
String runtime;
@Lob
String synopsis;
String posterPath;
String thumbnail;
// user movie comment rating
@OneToMany(cascade = CascadeType.ALL, mappedBy = "movie")
List<User_Movie_CR> userMovieCR;
// cinema movie
@OneToMany(cascade = CascadeType.ALL, mappedBy = "movie")
List<Cinema_Movie> cinemaMovie;
// user film cinema table
@OneToMany(mappedBy = "movie")
Set<Cinema_Movie_User> cinema_movie_user;
public Movie() {
}
public Movie(String name, String releaseDate, String critic,
String runtime, String synopsis, String posterPath, String thumbnail) {
this.name = name;
this.releaseDate = releaseDate;
this.critic = critic;
this.runtime = runtime;
this.synopsis = synopsis;
this.posterPath = posterPath;
this.thumbnail = thumbnail;
}
// toString
public String toString() {
return "Movie [name=" + name + ", releaseDate=" + releaseDate
+ ", critic=" + critic + ", runtime=" + runtime + ", synopsis="
+ synopsis + ", posterPath=" + posterPath + "]";
}
// setter and getter
}
ダオとファサードもありますが、元気に動いています！
ここに私のサービスがあります：
package de.hawhof.dm.kino.ws;
import java.util.ArrayList;
import java.util.List;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Request;
import javax.ws.rs.core.UriInfo;
import de.hawhof.dm.kino.facade.MovieFacade;
import de.hawhof.dm.kino.model.*;
@Path("/movies")
public class MoviesResource {
@Context
UriInfo uriInfo;
@Context
Request request;
MovieFacade movieFacade = new MovieFacade();
@GET
@Path("xml")
@Produces(MediaType.TEXT_XML)
public List<Movie> getMoviesBrowser() {
List<Movie> movies = new ArrayList<Movie>();
movies.addAll(movieFacade.listAll());
return movies;
}
@GET
@Path("XMLForApp")
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public List<Movie> getMovies() {
List<Movie> movies = new ArrayList<Movie>();
movies.addAll(movieFacade.listAll());
return movies;
}
@GET
@Path("onemovie")
public Movie getMovie() {
return new Movie("TEST!!!", "", "", "", "", "", "");
}
@GET
@Path("count")
@Produces(MediaType.TEXT_PLAIN)
public String getCount() {
int count = movieFacade.listAll().size();
return String.valueOf(count);
}
@Path("{movie}")
public MovieResource getMovie(@PathParam("movie") int movieid) {
return new MovieResource(uriInfo, request, movieid);
}
}
メソッド「onemovie」と「count」は正常に機能し、ブラウザにxmlが表示されますが、「XMLForApp」を呼び出すと、サーバーが例外をスローします。
私のクライアントはここにいます：
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.MediaType;
public class MovieWSClient {
Client client;
String movieList;
public MovieWSClient() {
client = ClientBuilder.newClient().register(getClass());
movieList = client.target("http://localhost:8080/kino").path("/rest/movies/XMLForApp").request(MediaType.APPLICATION_JSON).get(String.class);
}
public String getMovieList() {
return movieList;
}
}
例外は次のとおりです。
