Oracle spring启动休眠查询无效用户错误

嗨，我是春天靴子的新手。我尝试连接到Oracle并列出相关记录。我的代码在存根环境中工作，也就是说没有连接到数据库。当我试图从Spring连接到db时，我得到了编辑2中给出的错误：

HomeController

package blog.controllers;

import blog.models.Post;
import blog.services.PostService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;
import java.util.stream.Collectors;

@Controller
public class HomeController {

    @Autowired
    private PostService postService;

    @RequestMapping("/")
    public String index(Model model){

        List<Post> latest5Posts = postService.findLatest5();
        model.addAttribute("latest5posts", latest5Posts);

        List<Post> latest3Posts = latest5Posts.stream()
                .limit(3).collect(Collectors.toList());
        model.addAttribute("latest3posts", latest3Posts);

        return "index";

    }
}

用户实体类

package blog.models;

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

@Entity
@Table(name = "POSTS")
public class Post {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(nullable = false, length = 300)
    private String title;

    @Lob @Column(nullable = false)
    private String body;

    @ManyToOne(optional = false, fetch = FetchType.LAZY)
    private User author;

    @Column(nullable = false)
    private Date creation_date = new Date();

    public Long getId() {return id;}
    public void setId(Long id) {this.id = id;}
    public String getTitle() {return title;}
    public void setTitle(String title) {this.title = title;}

    public void setAuthor(User author) {this.author = author;}
    public Date getCreation_date() {return date;}
    public void setCreation_date(Date creation_date) {this.creation_date = creation_date;}

    public Post() { }

    public Post(Long id, String title, String body, User author) {

        this.id=id; this.title=title; this.body=body; this.author=author;
    }

    @Override
    public String toString() {
        return "Post{" + "id=" + id + ", title='" + title + '\'' +

p、 我还通过更改存储库尝试了以下方法：

@Query(value = "SELECT * FROM POSTS aa LEFT JOIN USERS bb ON aa.AUTHOR_ID=bb.ID", nativeQuery = true)

这次我出现了以下错误：

JPA查询的错误行（未使用本机查询时）

---

问题似乎如下：

由于这一特性：

spring.jpa.properties.hibernate.hbm2ddl.auto = update

由于Posts实体已更改为引用用户，Hibernate尝试添加外键约束：

alter table posts add constraint FK6xvn0811tkyo3nfjk2xvqx6ns foreign key (author_id) references users

但是得到这个错误：

ORA-02268: referenced table does not have a primary key

不确定为什么hibernate不向该表添加主键，因为@Id注释显然在那里

尝试手动向Users.id列添加主键约束：

ALTER TABLE users
 ADD CONSTRAINT users_pk PRIMARY KEY (id);

更新

package blog.services;

import blog.models.Post;
import org.springframework.stereotype.Service;

import java.util.List;


@Service
public interface PostService {

    List<Post> findAll();
    List<Post> findLatest5();
    Post findById(Long id);
    Post create(Post post);
    Post edit(Post post);
    void deleteById(Long id);
}

package blog.services;

import blog.models.User;

import java.util.List;

public interface UserService {

    List<User> findAll();
    User findById(Long id);
    User create(User user);
    User edit(User user);
    void deleteById(Long id);
}

在order by子句中使用Post.data映射时，可能会出现问题

医生说：

必须为持久字段或属性指定此批注 类型为java.util.Date和java.util.Calendar。可能只是 为这些类型的字段或属性指定

在使用java.util.Date时，需要添加以下内容：

@Temporal(TemporalType.DATE)
private Date date = new Date();
