Question

我正在使用Hibernate Envar进行审核。

这是我的代码和配置

hibernate.cfg.xml文件配置

<!-- Audit -->
        <listener class="org.hibernate.envers.event.AuditEventListener" type="post-insert"/>
        <listener class="org.hibernate.envers.event.AuditEventListener" type="post-update"/>
        <listener class="org.hibernate.envers.event.AuditEventListener" type="post-delete"/>
        <listener class="org.hibernate.envers.event.AuditEventListener" type="pre-collection-update"/>
        <listener class="org.hibernate.envers.event.AuditEventListener" type="pre-collection-remove"/>
        <listener class="org.hibernate.envers.event.AuditEventListener" type="post-collection-recreate"/>

使用@Audited

注释的一个示例实体

@Entity
@Table(name = "Users")
@Audited
public class User extends GenericDomain implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Column(length=100)
    private String name;
    @Column(length=60)
    private String username;
    @Column(length=130)
    private String password;
    // Getter and setter with more fields
}

我创建了一个RevistionEntity来记录已登录用户的审核，我们正在为其审核审核

@Entity
@Table(name = "REVISIONS")
@RevisionEntity(CustomRevisionListener.class)
public class CustomRevisionEntity {

    @Id
    @GeneratedValue
    @RevisionNumber
    private int id;
    @RevisionTimestamp
    private long audit_timestamp;
    private String username;
    private Long userid;
    // Getter and Setter
}

这是我的听众课程

public class CustomRevisionListener implements RevisionListener {

    public void newRevision(Object revisionEntity) {
        CustomRevisionEntity revision = (CustomRevisionEntity) revisionEntity;
        revision.setUsername("username"); //for testing
    }
}

对于插入/删除，它可以正常工作。

但是对于Update查询，它提供以下异常

这是我所有实体的通用更新代码

public E update(E entity) {
        getSession().update(entity);
        return entity;
    }

不幸的是，没有完整的堆栈跟踪和表的SQL定义，很难说这里发生了什么。这些是我要检查的事情：

审计表上的约束/ PK？ - 您的主键是否可能缺少修订号和修订类型 - 我发生这种情况是因为更新和删除发生在特定实体的同一会话中（我认为它与Cascade操作有关，但我现在不记得了），我期望实体表的修订号+ PK足以唯一地标识审计表中的每一行。
请记住，默认情况下，已删除的实体仅包含修订号，修订类型和原始实体的ID / PK。如果审计表上有NOT NULL约束，则可能导致失败。您可以将org.hibernate.envers.store_data_at_delete属性设置为true。
