java - 解码时出现 JAXB 意外元素错误

Question

如果有人能为我的问题找到解决方案，我将不胜感激......

从我的 WebService 调用 Web 方法时出现以下错误:

[com.sun.istack.SAXParseException2; lineNumber: 1; columnNumber: 223; unexpected element (uri:"", local:"sport"). Expected elements are <{}mostFavored>,<{}teamA>,<{}teamB>,<{http://sdl.ws.lsep.lskings.com/}scoring>,<{http://sdl.ws.lsep.lskings.com/}sport>,<{}gameId>,<{http://sdl.ws.lsep.lskings.com/}gameScoring>]

我想知道为什么消息包含元素“sport”以及为什么它与 <{http://sdl.ws.lsep.lskings.com/}sport> 不匹配。我认为这与 namespace 有关，但我无法解决该问题，到目前为止我已经被困了 2 个晚上......

我正在使用 JBossWS 工具生成客户端 Web 服务，所有内容都部署在 JBoss 7.1.1 上(但我认为这不相关)。请至少给我任何线索:)

这是 GameScoring 类:

@Entity
@Table(name = "`GAMESCORING`")
@XmlRootElement
@XmlType(name = "GameScoring", propOrder = { "gameScoringId", "scoring", "finished", "startTime", "stopTime",
    "tiebreak" })
public class GameScoring implements Serializable {
@Id
@GeneratedValue
@Column(name = "game_scoring_id")
private long gameScoringId;

@OneToMany(cascade = CascadeType.ALL, mappedBy = "scoring")
private List<GamePeriod> periods;

@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "scoring_id")
private Scoring scoring;

private boolean finished;

private Date startTime;

private Date stopTime;

private GamePeriod tiebreak;

public GameScoring() {
    super();
}

和客户端生成的同一个类:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "GameScoring", propOrder = {
"gameScoringId",
"scoring",
"finished",
"startTime",
"stopTime",
"tiebreak"
})

public class GameScoring {

protected long gameScoringId;
@XmlElement(namespace = "http://sdl.ws.lsep.lskings.com/")
protected Scoring scoring;
protected boolean finished;
@XmlSchemaType(name = "dateTime")
protected XMLGregorianCalendar startTime;
@XmlSchemaType(name = "dateTime")
protected XMLGregorianCalendar stopTime;
protected GamePeriod tiebreak;
+ getters/setters

我如何调用网络服务方法:

GameManagerService gm_service = new GameManagerService();
GameManagerPortType gm_port = gm_service.getGameManagerPort();
com.lskings.lsep.ws.sdl.Game game = gm_port.getMostFavored();

这里是 web 服务 SEI:

@WebService(name = "GameManagerPortType")
@SOAPBinding(style = Style.RPC, use = Use.LITERAL)
public interface GameManagerEndpoint {

@WebMethod
@WebResult(name = "success")
public boolean addGame(
        @WebParam(name = "sportId") String sportId,
        @WebParam(name = "leagueId") String leagueId,
        @WebParam(name = "scoringId") String scoringId,
        @WebParam(name = "participantHomeId") long participantHomeId,
        @WebParam(name = "participantAwayId") long participantAwayId);

@WebMethod
@WebResult(name = "success")
public boolean deleteGame(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "exists")
public boolean exists(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "game")
public Game getGame(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "gameList")
public List<Game> getGamesForLeague(@WebParam(name = "leagueId") long leagueId);

@WebMethod
@WebResult(name = "gameList")
public List<Game> search(@WebParam(name = "query") String query);

@WebMethod
@WebResult(name = "gameList")
public List<Game> getGamesForSport(@WebParam(name = "sportId") long sportId);

@WebMethod
@WebResult(name = "game")
public Game getMostFavored();

@WebMethod
@WebResult(name = "success")
public boolean setMostFavored(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "gamePeriods")
public List<GamePeriod> getPeriods(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "gamePeriodsWithTiebreaks")
public List<GamePeriod> getPeriodsWithTiebreaks(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "gameScore")
public int[] getScore(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "periodActions")
public List<GameAction> getPeriodActions(@WebParam(name = "periodId") long periodId);

@WebMethod
@WebResult(name = "allActions")
public List<GameAction> getAllActions(@WebParam(name = "gameId") long gameId);

@WebMethod
@WebResult(name = "gameTimer")
public String getGameTimer(@WebParam(name = "gameId") long gameId);

}

Answer 1

前几天发现跟@ManyToOne和@ManyToMany JPA注解有关。但是，我不确定为什么在使用这些注释时失败，@XmlTransient 注释解决了它。之后我只需要编写一些额外的代码来通过 id 获取相关对象。
