如何用spring boot为postgres sql设计一个包含图片和多种文本字段的表

@Entity
@Table(name = "posts")
public class Post {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Lob
    private byte[] image;

    @Column(length = 1000)
    private String text1;

    @Column(length = 1000)
    private String text2;

    // 省略构造函数、Getter和Setter方法
}

@Repository
public interface PostRepository extends JpaRepository<Post, Long> {
}

@RestController
@RequestMapping("/posts")
public class PostController {
    @Autowired
    private PostRepository postRepository;

    @PostMapping
    public Post createPost(@RequestBody Post post) {
        return postRepository.save(post);
    }

    @GetMapping("/{id}")
    public Optional<Post> getPost(@PathVariable Long id) {
        return postRepository.findById(id);
    }

    @PutMapping("/{id}")
    public Post updatePost(@PathVariable Long id, @RequestBody Post post) {
        post.setId(id);
        return postRepository.save(post);
    }

    @DeleteMapping("/{id}")
    public void deletePost(@PathVariable Long id) {
        postRepository.deleteById(id);
    }
}
