我将 Hibernate Envar 用于审计目的。

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"/>

一个使用@Audited 注释的示例实体

@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 来为已登录用户记录审计,我们将审计记录为

@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

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,它工作正常。

但是对于更新查询,它给出了以下异常

[ERROR] [http-8080-1 06:05:26] (JDBCExceptionReporter.java:logExceptions:101) Duplicate entry '1085-3' for key 1

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:

  1. 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特定实体在同一会话中发生了更新和删除(我认为它与级联操作有关,但我现在不记得了),我期望实体表的修订号 + PK 足以唯一标识审计表中的每一行。

  2. 请记住,默认删除的实体仅包含修订号、修订类型和原始实体的 ID/PK。如果您对审计表有 NOT NULL 约束,则可能会导致失败。您可以通过将org.hibernate.envers.store_data_at_delete属性设置为来解决此问题true
