Question

我有两个模型，即公司和用户。公司可以有很多用户。我使用Spring数据jpa与数据库进行交互。

用户模型：

REQ/REP

公司模式

@Entity
public class User {

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

    @Column(length = 50, unique = true)
    @NotNull
    @Size(min = 4, max = 50)
    private String username;

    @NotNull
    @Size(min = 8)
    private String password;

    @Column(length = 50)
    @NotNull
    @Size(min = 4, max = 50)
    private String firstName;

    @Column(length = 50)
    @NotNull
    @Size(min = 4, max = 50)
    private String lastName;

    @Column(length = 50, unique = true)
    @NotNull
    @Size(min = 4, max = 50)
    private String email;

    private Boolean enabled = true;

    @Temporal(TemporalType.TIMESTAMP)
    @UpdateTimestamp
    private Date lastPasswordReset;

    @Column(nullable = false, updatable = false)
    @Temporal(TemporalType.TIMESTAMP)
    @CreatedDate
    private Date createdAt = new Date();

    @Column(nullable = false)
    @Temporal(TemporalType.TIMESTAMP)
    @UpdateTimestamp
    @LastModifiedDate
    private Date updatedAt = new Date();

    @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinTable(
            name = "user_authority",
            joinColumns = {@JoinColumn(name = "user_id", referencedColumnName = "id")},
            inverseJoinColumns = {@JoinColumn(name = "authority_id", referencedColumnName = "id")})
    private List<Authority> authorities;

    @ManyToOne(optional = false, fetch = FetchType.LAZY, cascade = CascadeType.REMOVE)
    @JsonBackReference
    private Company company;

... Getter and Setters
}

所以我使用Spring Data JPA来保存公司，它也负责创建用户。所以今天如果由于某种原因导致用户的创建因某些异常而失败，那么公司记录仍然存在。所以我需要，如果创建用户失败，则不会创建公司（回滚）。我怎样才能做到这一点。

SpringBoot：如果子项创建失败，如何回滚创建父项？
