java - 使用复合主键映射 OneToOne 关系时出现 stackoverflow 错误
问题描述
我正在尝试使用三个表编写 OneToOne 关系： Owner、Property 和 OwnerProperty OwnerProperty 具有由属性和所有者图的 2 个外键组成的复合主键：
业主等级：
@Setter
@Getter
@Entity
@Table(name = "Owner")
public class Owner {
@Id
@GeneratedValue
private Long id;
@OneToOne(mappedBy="ownerPropertyKey.owner", cascade = CascadeType.ALL)
@JsonIgnoreProperties(value = "ownerPropertyKey.owner", allowSetters = true)
private OwnerProperty ownerProperty;
属性类：
@Setter
@Getter
@Entity
@Table(name = "Property")
public class Property {
@Id
@GeneratedValue
private Long id;
@OneToOne(mappedBy="ownerPropertyKey.property", cascade = CascadeType.ALL)
@JsonIgnoreProperties(value = "ownerPropertyKey.property", allowSetters = true)
private OwnerProperty ownerProperty;
所有者属性类：
@Setter
@Getter
@Entity
@Table(name = "OwnerProperty")
public class OwnerProperty {
@EmbeddedId
private OwnerPropertyKey ownerPropertyKey;
public OwnerProperty(OwnerPropertyKey ownerPropertyKey){
this.ownerPropertyKey = ownerPropertyKey;
}
public OwnerProperty(){
}
}
OwnerPropertyKey 类：
@Data
@Setter
@Getter
@Embeddable
public class OwnerPropertyKey implements Serializable {
@OneToOne
@JoinColumn(name = "owner_id", referencedColumnName = "id")
@JsonIgnoreProperties(value = "ownerProperty", allowSetters=true)
private Owner owner;
@OneToOne
@JoinColumn(name = "property_id", referencedColumnName = "id")
@JsonIgnoreProperties(value = "ownerProperty", allowSetters=true)
private Property property;
public OwnerPropertyKey(Owner owner, Property property){
this.owner = owner;
this.property = property;
}
public OwnerPropertyKey(){
}
}
当我尝试保存 ownerProperty 时出现错误：org.springframework.web.util.NestedServletException: Handler dispatch failed; 嵌套异常是 java.lang.StackOverflowError
