봄 : 'sessionFactory'라는 이름의 빈을 생성하는 중 오류가 발생했습니다.

Question

봄에 익숙하지 않고 다음과 같은 오류가 계속 발생하며 시간이 지나도 문제가 발견되지 않습니다. 어떤 도움을 주시면 감사하겠습니다!

내 MessagesEntity.java :

package models.entities; 

import javax.persistence.*; 
import java.util.Date; 

@Entity 
@Table(name = "usermessages", schema = "messages", catalog = "`") 
public class MessagesEntity { 
    @Id 
    @GeneratedValue(strategy= GenerationType.AUTO) 
    @Column(name = "id") 
    private long id;

    public String getMessage() {

    public void setUsername(String username) { 
     this.username = username;

    public Date getSentTime() { 
     return sentTime; 
    } 

    public void setSentTime(Date time) { 
     this.sentTime = time; 
    } 

    @Override 
    public boolean equals(Object o) { 
     if (this == o) return true; 
     if (o == null || getClass() != o.getClass()) return false; 

     MessagesEntity that = (MessagesEntity) o; 

     if (message != null ? !message.equals(that.message) : that.message != null) 
      return false;

     return true; 
    } 

    @Override

     int result = message != null ? message.hashCode() : 0; 
     result = 31 * result + (username != null ? username.hashCode() : 0); 
     result = 31 * result + (sentTime != null ? sentTime.hashCode() : 0);

    } 
}

나는 또한 다음과 같은 클래스를 생성 : MessageRepositoryImpl.java

import models.entities.MessagesEntity; 

import org.hibernate.SessionFactory; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Repository; 
import repositories.MessageRepository; 

@Repository 
public class MessageRepositoryImpl implements MessageRepository { 

    @Autowired 
    private SessionFactory sessionFactory; 

    @Override 
    public MessagesEntity getById(long id) { 
     return (MessagesEntity) sessionFactory.getCurrentSession().get(MessagesEntity.class, id); 
    } 
} 

MessageServiceImpl.java

import models.entities.MessagesEntity; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service; 
import org.springframework.transaction.annotation.Transactional; 
import repositories.MessageRepository; 
import services.MessageService; 

@Service 
public class MessageServiceImpl implements MessageService { 

    @Autowired 
    private MessageRepository messageRepo; 

    @Transactional 
    public MessagesEntity get(long id) { 
     return this.messageRepo.getById(id); 
    } 
} 

어떤 아이디어가?

Answer 1

님은 MessagesEntity에 catalog = "`"를 잘못 입력 한 것으로 보입니다. 카탈로그는 사용자가 데이터베이스의 서버 측에서 정의하는 "네임 스페이스"입니다.
