我将多对一映射问题。它看起来像是代码中的一个非常简单的错误,但我无法找到它...... 日志查询工作正常。
国家:
@Data
@Entity
@Table(name = "COUNTRIES", schema = "HR")
public class Country {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "COUNTRY_ID")
private Long id;
@Column(name = "COUNTRY_NAME")
private String name;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="REGION_ID")
private Region region;
}
区:
@Data
@Entity
@Table(name = "REGIONS", schema = "HR")
public class Region {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "REGION_ID")
private Long id;
@Column(name = "REGION_NAME")
private String name;
}
CountryRepository:
public interface CountryRepository extends CrudRepository<Country, Long> {
}
RegionRepository:
public interface RegionRepository extends CrudRepository<Region, Long> {
}
countryRepo.findAll();

答案 0 :(得分:0)
对我来说很好,但我删除了@Data
和@Table
注释。
