带有hibernate的com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException

Question

我无法看到问题出在哪里，我认为豆子里有某个地方，但我不知道在哪里。这是我的课程：

/* Desired result */

id A  B  C  dup_id
1  1  1  1  1
2  1  1  1  1
3  1  1  1  1

8  3  3  3  8
9  3  3  3  8
10 4  4  4  10

}

@Entity
@Table(name = "players")
public class Player implements Serializable {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Integer playerId;
@Column(name="player_name")
private String playerName;
@Column(name="player_country")
private String playerCountry;
@Column(name="player_championship_id")
private Integer championshipId;
@Column(name="player_team_id")
private Integer playerTeamId;

@JoinColumn(name="team_id",insertable=false,updatable=false)
private Team team;

public Integer getPlayerId() {
    return playerId;
}

public void setPlayerId(Integer playerId) {
    this.playerId = playerId;
}

public String getPlayerName() {
    return playerName;
}

public void setPlayerName(String playerName) {
    this.playerName = playerName;
}

public String getPlayerCountry() {
    return playerCountry;
}

public void setPlayerCountry(String playerCountry) {
    this.playerCountry = playerCountry;
}

public Championship getChampionship() {
    return championship;
}

public void setChampionship(Championship championship) {
    this.championship = championship;
}

public Team getTeam() {
    return team;
}

public void setTeam(Team team) {
    this.team = team;
}

}

@Entity
@Table(name = "teams")
public class Team {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="team_id")
private Integer teamId;
@Column(name="team_name")
private String teamName;
@Column(name="team_country")
private String teamCountry;
@Column(name="team_points")
private Double teamPoints;
@Column(name="team_championship_id")
private Integer championshipId;


@ManyToOne(fetch=FetchType.EAGER)
@JoinColumn(name="championship_id",insertable=false,updatable=false)
private Championship championship;
@OneToMany(mappedBy="team",fetch=FetchType.LAZY, cascade=CascadeType.REMOVE)
private List<Player> players;


public String getTeamName() {
    return teamName;
}
public void setTeamName(String teamName) {
    this.teamName = teamName;
}
public String getTeamCountry() {
    return teamCountry;
}
public void setTeamCountry(String teamCountry) {
    this.teamCountry = teamCountry;
}
public Double getTeamPoints() {
    return teamPoints;
}
public void setTeamPoints(Double teamPoints) {
    this.teamPoints = teamPoints;
}
public Integer getTeamId() {
    return teamId;
}
public void setTeamId(Integer teamId) {
    this.teamId = teamId;
}
public Championship getChampionship() {
    return championship;
}
public void setChampionship(Championship championship) {
    this.championship = championship;
}
public List<Player> getPlayers() {
    return players;
}
public void setPlayers(List<Player> players) {
    this.players = players;
}

以下是从我的数据库中检索数据的方法：

@Entity
@Table(name="championships")
@Component
public class Championship implements Serializable {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Integer championshipId;
@Column(name="championship_current_round")
private Integer currentRound;
@Column(name="championship_no_rounds")
private Integer noRounds;
@Column(name="championship_name")
private String championshipName;

@OneToMany(mappedBy="championship",fetch=FetchType.LAZY, cascade=CascadeType.REMOVE)
private List<Player>players;
@OneToMany(mappedBy="championship",fetch=FetchType.LAZY, cascade=CascadeType.REMOVE)
private List<Team>teams;

public Integer getChampionshipId() {
    return championshipId;
}
public void setChampionshipId(Integer championshipId) {
    this.championshipId = championshipId;
}
public Integer getCurrentRound() {
    return currentRound;
}
public void setCurrentRound(Integer currentRound) {
    this.currentRound = currentRound;
}
public Integer getNoRounds() {
    return noRounds;
}
public void setNoRounds(Integer noRounds) {
    this.noRounds = noRounds;
}
public String getChampionshipName() {
    return championshipName;
}
public void setChampionshipName(String championshipName) {
    this.championshipName = championshipName;
}



}

这是堆栈跟踪：

public T findById(Integer id){
    return (T) sessionFactory.getCurrentSession().get(managedClass.getClass(),(Serializable) id);
}
public List<T> findAll(){
    List<T>result= (List<T>)sessionFactory.getCurrentSession().createCriteria(managedClass.getClass()).list();
    return result;

}

问题在于：
