Kafka监听器集成JPA启动崩溃问题求助

尝试将数据库集成到Kafka监听器中时，程序启动即崩溃，核心错误为Hibernate抛出的org.hibernate.AnnotationException: No identifier specified for entity。

实体类LogQuestor #

package br.com.ottimizza.ListenerServico.domain.model;

import java.math.BigInteger;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Table;

import org.springframework.data.annotation.Id;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.NoArgsConstructor;
import lombok.Data;

@Data
@Entity
@Builder(toBuilder = true)
@AllArgsConstructor
@NoArgsConstructor
@Table(name = "ot_log_questor_post_baixa")
public class LogQuestor {
  
  @Id
  @Column
  @GeneratedValue(strategy = GenerationType.AUTO)
  private BigInteger id;

  @Column
  Date ot_created_at;
  
  @Column
  Body ot_objeto_questor;
  
  @Column
  String ot_objeto_texto_questor;

  @Column
  String ot_status_req;

  @Column
  String ot_token_usuario;

} 

Body实体类 #

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Body implements Serializable {

  private static final long serialVersionUID = 1L;
  
  String fileLink;

  String zenTokenUsuario;

  String domain;

  String filename;

  String cnpj;

  HashMap<String, String> propriedades;

}

Repository接口 #

package br.com.ottimizza.ListenerServico.repository;

import java.math.BigInteger;
import java.util.Optional;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import br.com.ottimizza.ListenerServico.domain.model.LogQuestor;

@Repository
public interface LogQuestorRepository extends JpaRepository<LogQuestor, BigInteger> {
  
  public Optional<LogQuestor> findById(BigInteger id);
}

保存方法 #

import org.springframework.stereotype.Service;
import org.springframework.beans.factory.annotation.Autowired;

  @Autowired
  LogQuestorRepository repository;

  public void saveToDB(String message, String status, String token) {
    LogQuestor reqToSv = new LogQuestor();
    //assignment of carachteristics
    repository.save(reqToSv);
  } 

注：代码省略了部分无关内容，确认无错误。

问题原因及修复 #

核心错误为**org.hibernate.AnnotationException: No identifier specified for entity**，原因是LogQuestor实体类错误使用了org.springframework.data.annotation.Id注解，Hibernate作为JPA实现，只能识别JPA标准的主键注解。

修复方式：将LogQuestor类中的import org.springframework.data.annotation.Id替换为import javax.persistence.Id，修改后的主键代码片段如下：

import javax.persistence.Id;

// ...

@Id
@Column
@GeneratedValue(strategy = GenerationType.AUTO)
private BigInteger id;
