如何在spring jpa中以一对多关系插入数据

Question

我是春天的新手。我想将数据插入到AUDIT 表中。 USER 和 AUDIT 表之间存在一对多关系。

对于每个登录和注销数据都应该插入到AUDIT 表中。我该怎么做？

用户实体：

@Table(name="USER")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="USERID")
    private Long id;

    private String username;

    private String email;

    private Long phone;

    private String password;

    private int OTP;

    private boolean activation_flag;

    @OneToMany(cascade=CascadeType.ALL)
    @JoinColumn(name="USERID")
    private Set<Audit> audit;

    @ManyToOne
    @JoinColumn(name="ADDRESSID")
    private Address address;

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(
            name = "USER_AUTHORITY",
            joinColumns = {@JoinColumn(name = "USER_ID", referencedColumnName = "USERID")},
            inverseJoinColumns = {@JoinColumn(name = "AUTHORITY_ID", referencedColumnName = "ID")})
    private List<Authority> authorities;

审计实体：

@Entity
@Table(name="AUDIT")
public class Audit {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="AUDITID")
    private long auditid;

    @Column(name="GEOLOCATION")
    private String geolocation;

    @Column(name="ACTION")
    private String action;

    @Column(name="DATETIME")
    private Date datetime;

    @Column(name="DEVICEID")
    private long deviceid;

    @Column(name="ACTIONSUCCESS_FAIL")
    private boolean actionsuccess_fail;

    @Column(name="JWT_TOKEN")
    @Type(type="text")
    private String JWT_token;

    @ManyToOne
    private User user;

审计存储库：

public interface AuditRepository extends JpaRepository<Audit, Long> {
}

用户存储库：

public interface UserRepository extends JpaRepository<User, Long> {

    User findByUsername(String username);
    User findByEmail(String email);
    User findByPhone(Long phone);
    User findById(Long id);

}

将审核添加到您希望审核关联的用户，然后保存。
