Question

我有两个使用相同数据库的Spring Boot应用程序。主要应用程序充分利用了数据库，另一个应用程序用于报告（基本上是读取主要应用程序创建的数据）。

主应用程序使用envers（org.hibernate：hibernate-envers：5.3.1.Final），它创建审核表以跟踪更改（表由liquibase创建）。我需要通过报表应用读取历史数据，因此我也向该应用添加了envers。以下是报告应用程序的一些摘要。

实体示例：

@Entity
@Table(name = "applications")
@Audited
@AuditOverride(forClass = BaseEntity.class)
@EqualsAndHashCode(callSuper = true)
@Getter
public class ApplicationEntity extends BaseEntity {

    @ManyToOne(optional = false)
    @JoinColumn(name = "client_id")
    private ClientEntity client;

    private BigDecimal amount;
}

超类：

@MappedSuperclass
@EntityListeners({PreventModificationsListener.class})
@ToString(of = "id")
@EqualsAndHashCode(of = "id")
@Getter
public abstract class BaseEntity {

    @VisibleForTesting
    @Setter(PACKAGE)
    @Id
    private Long id;

    @Version
    private Long version;
}

配置：

spring:
  jpa:
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQL95Dialect
        id:
          new_generator_mappings: true
        defaultSchema: public
        order_updates: true
        jdbc:
          fetch_size: 0
        hbm2ddl:
          auto: validate
        show_sql: false
        format_sql: false
        enable_lazy_load_no_trans: true
      org.hibernate:
        envers:
          audit_table_prefix: audit_
          audit_table_suffix:

结果报告应用在模式验证启动期间失败：

我们非常感谢您的帮助和建议。

我的一位同事指出了两个应用程序之间的差异，事实证明这是缺少的链接。

修订实体类：

@Entity
@Table(name = "audit_revisions")
@SequenceGenerator(name = "seq_gen", sequenceName = "audit_revisions_seq", allocationSize = 1)
@RevisionEntity
@EntityListeners(AuditingEntityListener.class)
@Getter
public class AuditRevision {
    @Id
    @GeneratedValue(generator = "seq_gen", strategy = SEQUENCE)
    @RevisionNumber
    private Long id;

    @RevisionTimestamp
    private Date revisionDate;

    @CreatedBy
    private String createdBy;
}

具有envers的应用程序在架构验证上失败：REV列的类型错误-找到[int8（Types＃BIGINT）]，但是期望[int4（Types＃INTEGER）]
