这个问题已经在这里有了答案： > hibernate column name issues 9个
使用Spring JPA无法将数据保存到数据库中的表.
我有这样的实体类：
@Entity
@Table(name = "topics")
public class TopicBean implements Serializable {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "topicId")
private String topicId;
@Column(name = "title")
private String title;
@Column(name = "details")
private String details;
@Column(name = "username")
private String username;
@Column(name = "userImage")
private String userImage;
@Column(name = "dayPosted")
private String dayPosted;
//Getters and setters
}
服务接口：
public interface TopicService {
TopicBean findById(long id);
TopicBean findByName(String name);
void saveTopic(TopicBean topicBean);
void updateTopic(TopicBean topicBean);
TopicBean findByTopicId(String id);
void deleteTopicById(long id);
List<TopicBean> findAllTopics();
void deleteAllTopics();
public boolean isTopicExist(TopicBean topicBean);
}
服务Impl：
@Component
public class TopicServiceImplementation implements TopicService {
@Autowired
private TopicRepository topicRepository;
@Override
public TopicBean findById(long id) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public TopicBean findByName(String name) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public void saveTopic(TopicBean topicBean) {
topicRepository.save(topicBean);
}
@Override
public void updateTopic(TopicBean topicBean) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public void deleteTopicById(long id) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public List<TopicBean> findAllTopics() {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public void deleteAllTopics() {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public boolean isTopicExist(TopicBean topicBean) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
@Override
public TopicBean findByTopicId(String id) {
return topicRepository.findByTopicId(id);
}
}
仓库：
@Repository
public interface TopicRepository extends JpaRepository<TopicBean, Long> {
TopicBean findByTopicId(String topicId);
}
休息电话：
@RequestMapping(path = "/new_topic", method = RequestMethod.POST)
public ResponseEntity new_topic(@RequestBody TopicBean topics) throws Exception {
System.out.println("new topic called java: " + topics);
topicService.saveTopic(topics);
HttpHeaders headers = new HttpHeaders();
headers.add("success", "topic added");
return new ResponseEntity(headers, HttpStatus.OK);
}
DB中的表结构：
id
topicId
title
details
dayPosted
username
userImage
尝试保存数据时出现错误.一切看起来都不错,但仍然会引发有关数据库中列的错误,即我在数据库中没有的topic_id.

解决方法:
这可能是因为,Spring Boot使用改良的NamingStrategy作为默认命名策略.
您可以尝试使用以下配置将命名策略更改为默认设置.
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.DefaultNamingStrategy
