我正在使用Glassfish 4和JPA 2.1和Netbeans 7。

为了生成表，我有这些bean：

@Entity
public class Myuser implements Serializable{

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long myuserId;

    @Column(name = "firstname")
    private String firstName;

    @Column(name = "lastname")
    private String lastName;

    @Column(name = "mail")
    private String mail;

    @Column(name = "password")
    private String password;

    @OneToMany @JoinColumn(name = "user", insertable=false, updatable=false)
    private Collection<Course> courses;

//...
}

@Entity
public class Course implements Serializable{

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long courseId;

    @Column(name = "coursename")
    private String courseName;

    @Column(name = "duration")
    private int duration; 

    @Column(name = "description")
    private String description;

    @ManyToOne @JoinColumn(name="myuserId", insertable=false, updatable = false)
    private Myuser user;

    @OneToMany @JoinColumn(name ="course", insertable=false, updatable = false)
    private Collection<Mymodule> modules;

//...
}

我收到了这个服务器数据库日志消息：

2 个答案:

答案 0 :(得分：2)

看起来“用户”栏就是问题所在。 “USER”是reserved word in Derby，因此不应该用作列名。如果您必须将其用作列名，请务必将其括在引号中，如question所示。

答案 1 :(得分：0)

我猜'user'是一个数据库关键字，无法使用！您必须更改映射以使用其他列名称。
