Java HSQLDB无法从JPA注释正确识别主键

我们使用Oracle作为生产数据库，使用HSQLDB作为单元测试数据库。这两种环境都使用Hibernate作为JPA提供程序。以下代码在生产环境中正常工作，但在jUnit下运行时抛出

SQL错误：-104，SQLState:23505-完整性约束冲突：唯一约束或索引冲突。所涉实体为：

@Entity
@Table(name="TT_TEACHERSECTIONGROUP")
public class TeacherSectionGroup implements TeacherSectionListItem {
  @Id
  @Column(name="TEACHERSECTIONGROUPID",unique=true,nullable=false)
  @GeneratedValue(strategy=GenerationType.AUTO,generator="TT_TEACHERSECTIONGROUPID_SEQUENCE")
  @SequenceGenerator(name="TT_TEACHERSECTIONGROUPID_SEQUENCE",sequenceName="TT_TEACHERSECTIONGROUP_SQ")
  private Long id;
    .
    .
    .
  @OneToMany(fetch=FetchType.LAZY,cascade=CascadeType.DETACH)
  @JoinTable(name="TT_TEACHERSECTIONGROUPASSOC",joinColumns={
    @JoinColumn(name="TEACHERSECTIONGROUPID",referencedColumnName="TEACHERSECTIONGROUPID")
  },inverseJoinColumns={
    @JoinColumn(name="USERSDCID",referencedColumnName="USERSDCID"),
    @JoinColumn(name="SECTIONSDCID",referencedColumnName="SECTIONSDCID")
  })
  private List<TeacherSection> sections;
    .
    .
    .

使用主键类：

@Embeddable
public class TeacherSectionPK implements Serializable {
  @Column(name="SECTIONSDCID",nullable=false)
  private Long sectionId;

  @Column(name="USERSDCID",nullable=false)
  private Long usersDcid;
    .
    .
    .

日志中的（已清理）输出包含正在发出的以下hibernate语句：

HSQLDB似乎只使用反向连接列作为JoinTable的主键，而不是所有列，这是有道理的（正如我在inter-Tube中看到的文档）

是否有一种机制我没有指定给HSQLDB哪些字段应该包含在主键中？由于这段代码实际上在Oracle（即生产环境）中正常工作，我不愿意重写它只是为了满足单元测试，所以我希望有一个答案在这两种环境中都同样有效。谢谢。
我认为区别在于您正在使用JPA在HSQL上创建表，但该模式在Oracle上已经存在。如果是这样的话，你有没有尝试过将你的关系指定为多人而不是一个多人。当您已经指定了一个联接表时，两者之间没有太大区别，但是我相信Hibernate处理DDL gen的方式不同您是否尝试将
@GeneratedValue
策略从
GenerationType.AUTO
更改为
GenerationType.SEQUENCE
？据我所知，
序列
策略利用生成器和序列配置。而且您不需要将
@Id
的
@Column
设置为必需的
和
nullable=false
，因为它已经隐式设置了。@chris，改为ManyToMany完成了这个技巧。如果你想加上这个答案，我很乐意把它标为正确答案。
