Use two one-to-many mappings instead: @Entity @Table(name = "bar" ) public class Bar { @GeneratedValue(strategy = GenerationType.IDENTITY) @Id private Long id; @OneToMany(mappedBy = "bar" ) private List<FooBar> fooBars; } @Entity @Table(name = "foo" ) public class Foo { @GeneratedValue(strategy = GenerationType.IDENTITY) @Id private Long id; @ManyToMany(mappedBy = "foo" , cascade = CascadeType.ALL) private List<FooBar> fooBars; } @Entity @Table(name = "foo_bar" ) public class FooBar { @GeneratedValue(strategy = GenerationType.IDENTITY) @Id private Long id; @ManyToOne(fetch = FetchType.LAZY) private Bar bar; @ManyToOne(fetch = FetchType.LAZY) private Foo foo; private String note; @PrePersist void prePersist(){ setNote( "XXXXX" ); } } ( https://hibernate.atlassian.net/browse/HHH-16300#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16300#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
