我有測試平臺，其中有2個模型與ManyToOne連接。 Aaaaaand這是行不通的。休眠無法映射2個模型
@Entity
@Table(name = "Tests")
public class Test {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
private String name;
private int count;
private String description;
private boolean free;
@ManyToOne
@JoinColumn(name = "authorId")
private User tAuthor;
private String section;
@OneToMany(mappedBy = "rTest", fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private List<Result> results = new ArrayList<Result>();
@OneToMany(mappedBy = "qTest", fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private List<Question> questions = new ArrayList<Question>();
private String commentToAdmin;
@Column(length = 32, columnDefinition = "varchar(32) default 'Developing'")
@Enumerated(EnumType.STRING)
private TestStatus status = TestStatus.Developing;
@CreationTimestamp
private Timestamp createdOn;
@UpdateTimestamp
private Timestamp updateDateTime;
模式2：
@Entity
@Table(name = "users")
public class User {
private Long id;
private String username;
private String password;
private String passwordConfirm;
@OneToMany(mappedBy = "tAuthor", fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private List<Test> listTests = new ArrayList<Test>();
private Set<Role> roles;
@OneToMany(mappedBy = "rUser", fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private List<Result> result = new ArrayList<Result>();
@CreationTimestamp
private Timestamp dateRegistration;
