上面代码不完整。

```
@Data
@Entity
public class User {
@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(
name = "user_role",
joinColumns = @JoinColumn(name = "user_id"),
inverseJoinColumns = @JoinColumn(name = "role_id")
)
private List<Role> roles;
}

@Data
@Entity
public class Role {
@JsonIgnore
@ManyToMany(mappedBy = "roles")
List<User> users;
}
```

刚在 Spring Boot 2.7.16 测了，也不行。貌似只能用 `@Transient` 了？
