Hello, I have the following class structure:
| @Entity | @Table(name="FOO") | @IdClass(FooPK.class) | public class Foo { | private Long id; | private String name; | private String description; | private List<FooBar> bars; | | @Id @Column(name="FOO_ID") | public Long getId() { | return id; | } | public void setId(Long id) { | this.id = id; | } | | @Id @Column(name="FOO_NAME") | public String getName() { | return name; | } | public void setName(String name) { | this.name = name; | } | | public static class FooPK { | private Long id; | private String name; | | @Id @Column(name="FOO_ID") | public Long getId() { | return id; | } | public void setId(Long id) { | this.id = id; | } | | @Id @Column(name="FOO_NAME") | public String getName() { | return name; | } | public void setName(String name) { | this.name = name; | } | } | } | | | @Entity | @Table(name="BAR") | @IdClass(BarPK.class) | public class Bar { | private Long id; | private String name; | private String description; | | @Id @Column(name="BAR_ID") | public Long getId() { | return id; | } | public void setId(Long id) { | this.id = id; | } | | @Id @Column(name="BAR_NAME") | public String getName() { | return name; | } | public void setName(String name) { | this.name = name; | } | | public static class BarPK { | private Long id; | private String name; | | @Id @Column(name="BAR_ID") | public Long getId() { | return id; | } | public void setId(Long id) { | this.id = id; | } | | @Id @Column(name="BAR_NAME") | public String getName() { | return name; | } | public void setName(String name) { | this.name = name; | } | } | } | | | @Entity | @Table(name="FOO_BAR") | @IdClass(FooBarPK.class) | public class FooBar { | private Foo foo; | private Bar bar; | private Date effectiveDate; | private Date endDate; | | @Id @JoinColumn(name="FOO_ID") | public Foo getFoo() { | return foo; | } | @Id @JoinColumn(name="BAR_ID") | public Bar getBar() { | return bar; | } | @Id @Column(name="EFF_DATE") | public Date getEffectiveDate() { | return effectiveDate; | } | | public static class FooBarPK { | private Foo foo; | private Bar bar; | private Date effectiveDate; | | @Column(name="FOO_ID") | public Foo getFoo() { | return foo; | } | @Column(name="BAR_ID") | public Bar getBar() { | return bar; | } | @Column(name="EFF_DATE") | public Date getEffectiveDate() { | return effectiveDate; | } | } | } | The question I have relates to the FooBar class. The table behind it has FOO_ID and BAR_ID columns as part of the primary key. But I can't seem to figure out how to map these column values to appropriate Foo.id and Bar.id values. Any ideas on how I might be able to do this? Thanks for your help.
