我在春季启动项目中使用的是func captureOutput(_ output: AVCaptureOutput!, didOutput sampleBuffer: CMSampleBuffer!, from connection: AVCaptureConnection!)
，但我有lombok 1.18.6，但仍然有@NoArgsConstructor
下面是我的org.springframework.orm.jpa.JpaSystemException: No default constructor for entity: : com.validation.entity.Client; nested exception is org.hibernate.InstantiationException: No default constructor for entity: : com.validation.entity.Client] with root cause实体
Client下面是我的import lombok.AccessLevel
import lombok.Data
import lombok.NoArgsConstructor
import org.hibernate.annotations.Fetch
import org.hibernate.annotations.FetchMode
import org.hibernate.annotations.Nationalized
import javax.persistence.CascadeType
import javax.persistence.Column
import javax.persistence.Entity
import javax.persistence.GeneratedValue
import javax.persistence.GenerationType
import javax.persistence.Id
import javax.persistence.OneToMany
@Data
@NoArgsConstructor(access = AccessLevel.PUBLIC)
@Entity
class Client implements Serializable {
private static final long serialVersionUID = 1L
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id
@Nationalized
@Column(unique = true, nullable = false)
private String name
@Column(nullable = false)
private boolean active
@Nationalized
@Column(unique = true, nullable = false)
private String externalId
@Fetch(value = FetchMode.SELECT)
@OneToMany(mappedBy="client", cascade=CascadeType.ALL, targetEntity = RuleSet.class)
private Set<RuleSet> ruleSets
Client(String name, boolean active, String externalId){
this.name = name
this.active = active
this.externalId = externalId
}
}
ClientRepository有人可以帮我，为什么即使有import com.validation.entity.Client
import com.validation.entity.RuleDefinition
import org.springframework.data.repository.CrudRepository
import org.springframework.data.repository.PagingAndSortingRepository
import org.springframework.data.repository.query.Param
interface ClientRepository extends PagingAndSortingRepository<Client, Long> {
Client findByName(@Param("name")String name)
Client findByNameIgnoreCase(@Param("name")String name)
Client findByExternalId(@Param("lawId")String id)
Client findByExternalIdIgnoreCase(@Param("lawId")String id)
Client findByRuleSetsId(Long id)
Set<Client> findByNameIgnoreCaseOrExternalIdIgnoreCase(@Param("name")String name,@Param("lawId")String id)
Set<Client> findByNameContainingIgnoreCase(@Param("name")String name)
}
我也得到No default constructor for entity
下面是我提出请求@NoArgsConstructor(access = AccessLevel.PUBLIC)时的完整stacktrace

Client答案 0 :(得分：4)
基于反编译的输出，您正在使用Groovy，而不是Java。 Lombok doesn't work well with Groovy。您的反编译代码显示了这一点，没有Lombok增强，例如@Data不会创建吸气剂。
如果计划继续将Lombok与Groovy混合使用，则需要重新访问项目设置。我个人不会将这两件事混在一起。
答案 1 :(得分：0)
就像上面和Lombok doesn't work well with Groovy中所述，Lombok不能很好地与Java配合使用是不正确的。
在Groovy代码中使用带有Lombok注释的Java对象没有问题，请参见此处的示例 here
Groovy代码中的Lombok批注将被忽略。 Groovy不支持Lombok批注。因此，这不仅仅是Groovy的问题，反之亦然。
使相对论不同时使用。我认为这就是基于JVM的语言的全部要点：“相对”的良好互操作性（Java，Groovy，JRuby，Kotlin等）。
