我有这2个表（主表和详细信息，请注意第二个表有一个复合键）
CREATE TABLE MESTRE (
ID INTEGER NOT NULL,
DESCRICAO VARCHAR(50) NOT NULL
);
ALTER TABLE MESTRE ADD CONSTRAINT PK_MESTRE PRIMARY KEY (ID);
CREATE TABLE DETALHE (
MESTRE_ID INTEGER NOT NULL,
ID INTEGER NOT NULL,
DESCRICAO VARCHAR(50)
);
ALTER TABLE DETALHE ADD CONSTRAINT PK_DETAHLE PRIMARY KEY (MESTRE_ID, ID);
ALTER TABLE DETALHE ADD CONSTRAINT FK_DETAHLE_1 FOREIGN KEY (MESTRE_ID) REFERENCES MESTRE (ID);
对于这2个表，我有这个JPA映射：
@Entity
@Table(name = "MESTRE")
public class Mestre {
@Id
@Column(name = "ID")
@GeneratedValue(generator = "COD_PVEITE", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "COD_PVEITE", sequenceName = "COD_PVEITE", allocationSize = 1, initialValue = 1)
private Integer id;
@Column(name = "DESCRICAO")
private String descricao;
@OneToMany(mappedBy = "mestre", cascade = CascadeType.ALL)
private List<Detalhe> detalhes = new ArrayList<Detalhe>(0);
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getDescricao() {
return descricao;
}
public void setDescricao(String descricao) {
this.descricao = descricao;
}
public List<Detalhe> getDetalhes() {
return detalhes;
}
public void setDetalhes(List<Detalhe> detalhes) {
this.detalhes = detalhes;
}
}
@Entity
@Table(name = "DETALHE")
@IdClass(Detalhe.PK.class)
public class Detalhe {
public static class PK implements Serializable {
private Integer metreId;
private Integer id;
public PK() {
}
public PK(Integer metreId, Integer id) {
this.metreId = metreId;
this.id = id;
}
public Integer getMetreId() {
return metreId;
}
public void setMetreId(Integer metreId) {
this.metreId = metreId;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
result = prime * result + ((metreId == null) ? 0 : metreId.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
PK other = (PK) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
if (metreId == null) {
if (other.metreId != null)
return false;
} else if (!metreId.equals(other.metreId))
return false;
return true;
}
}
@Id
@Column(name = "MESTRE_ID", insertable = false, updatable = false)
private Integer metreId;
@Id
@GeneratedValue(generator = "COD_PVEITE", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "COD_PVEITE", sequenceName = "COD_PVEITE", allocationSize = 1, initialValue = 1)
private Integer id;
@ManyToOne
@JoinColumn(name = "MESTRE_ID", referencedColumnName = "ID")
private Mestre mestre;
@Column(name = "DESCRICAO")
private String descricao;
public Integer getMetreId() {
return metreId;
}
public void setMetreId(Integer metreId) {
this.metreId = metreId;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Mestre getMestre() {
return mestre;
}
public void setMestre(Mestre mestre) {
this.mestre = mestre;
}
public String getDescricao() {
return descricao;
}
public void setDescricao(String descricao) {
this.descricao = descricao;
}
}
当我查询这些实体时，没有问题：
Mestre mestre = entityManager.find(Mestre.class, 1);
for (Detalhe detalhe : mestre.getDetalhes() {
// do the stuff
}
但是当我试图坚持新的Mestre时，会出现异常。
Detalhe d = new Detalhe();
Mestre m = new Mestre();
m.setDescricao("mestre");
d.setMestre(m);
d.setDescricao("detalhe");
m.getDetalhes().add(d);
em.persist(m);
