1 Caused by: org.hibernate.AnnotationException: No identifier specified for entity: com.xxx.ProjectDTO
@MappedSuperclass标注为映射的父类，即可解决上述问题
@Entity

@MappedSuperclass
public class BaseDTO { ... }

Caused by: org.hibernate.MappingException: Could not determine type for: com.asing1elife.teamnote.dto.ProjectGroupDTO, at table: al_project, for columns: [org.hibernate.mapping.Column(project_group)]
@ManyToOne还是@OneToMay，或其他对象映射规则@Entity @Table(name = "al_project") public class ProjectDTO extends BaseDTO { @Column private ProjectGroupDTO projectGroup; }
java.sql.SQLSyntaxErrorException: Table ‘asl_station.hibernate_sequence‘ doesn‘t exist
public class BaseDTO { @Id @GeneratedValue private Long id = 0L; }
@GeneratedValue直接指定生成规则，就会抛出上述异常GeneratedType.AUTOauto_increment，这对应的应该是GenerationType.IDENTITYpublic class BaseDTO { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id = 0L; }

hibernateLazyInitializer属性，改属性在进行JSON转换时抛出异常com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.asing1elife.teamnote.core.bean.ResponseData["data"]->com.asing1elife.teamnote.dto.OrganizationDTO$HibernateProxy$f3Tr4vBI["hibernateLazyInitializer"])
@JsonIgnoreProperties("hibernateLazyInitializer")，确保数据转换时会过滤掉休眠生成的属性
@JsonIgnoreProperties("hibernateLazyInitializer")
public class BaseDTO { ... }
disable SerializationFeature.FAIL_ON_EMPTY_BEANS可以尝试将JSON转换时的以下属性设置为falsespring: jackson: serialization: fail-on-empty-beans: false
(although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)
