使用spring boot Jpa插入mysql无法正常工作

问题描述 投票：0回答：1

我试图在春季启动时使用JpaRepository将数据持久化到Mysql数据库中，但是我一直收到以下错误，不确定是怎么回事

   java.sql.SQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails (`pool`.`cart`, CONSTRAINT `cart_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`))

我的模型类看起来像这样

@Entity
@Table(name = "cart")
public class Cart {

    @Id
    @Column(name = "id", unique = true, nullable = false)
    private String id;
    @Column(name = "user_id")
    private int userId;

    public Cart() {
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }
}

我的控制器

    @RequestMapping("/api/v1/cart")
@RestController
public class CartController {

    @Autowired
    CartRepository cartRepository;


    @PostMapping(value = "/postCart")
    public String postCart(@RequestBody Cart cart){
        cartRepository.save(cart);
        return "Success";
    }
}

我的存储库

    @Repository
public interface CartRepository extends JpaRepository<Cart, String> {


}

我在做什么错，有没有更好的方法来保留数据

更新：这是邮递员正在使用的数据

{
    "id": "QWERTY",
    "user_id": 1
}

但是当我记录以上数据时，它返回上面的id，但是user_id总是返回0

mysql spring-boot jpa spring-data-jpa

编辑：看到堆栈跟踪之后，这似乎也有所帮助：could not execute statement SQL constraint [id] nested exception is org.hibernate.exception.ConstraintViolationException

同样，这个问题似乎是因为cart.user_id是引用用户类中user.id的外键，这违反了一些约束。
