Почему Spring не может воссоздать таблицы в отношениях @ManyToMany?

/ 10 марта 2020

Я использую Spring с базой данных H2 и JPA. У меня есть отношение @ManyToMany между пользователем и ролью.

Пользователь: 

@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;

    private String lastName;

    private String email;

    @ManyToMany(cascade = CascadeType.ALL )
    @JoinTable(
            name = "User_Role",
            joinColumns = { @JoinColumn(name = "user_id") },
            inverseJoinColumns = { @JoinColumn(name = "role_id") }
    )
    private Set<Role> roles;
}

Роль: 


@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
public class Role {

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

    private String roleName;

    @ManyToMany(mappedBy = "roles")
    @Cascade(value = org.hibernate.annotations.CascadeType.ALL)
    private Set<User> users;
}

В @ManyToMany необходимо создать дополнительную таблицу .

В application.properties я хочу воссоздать таблицы при запуске приложения. 

spring.jpa.hibernate.ddl-auto = create

Ошибка, которую я имею:

Проблема в том, что таблица Роль не может быть отброшен, потому что от этого зависит другая таблица. Единственный способ, который мне помог, - это вручную удалять файл .mv.db каждый раз, прежде чем я хочу запустить приложение.

PS Это мой первый пост. Извините, если я неясно описал это.
