Question

我正在尝试处理由于Javers表创建错误而无法启动的应用程序（问题归因于应用程序数据库问题）。有没有一种方法可以防止Javers在应用程序启动期间创建表（如jv_commit之类的表），以便我可以在DBA修复数据库问题的同时在该应用程序上工作（这需要时间）？

我在application.yml中添加了以下内容（不确定其正确方法）

  Javers:
           sqlSchemaManagementEnabled: false
           auditableAspectEnabled: false
           springDataAuditableRepositoryAspectEnabled: false

我也在所有存储库类中都注释掉了@JaversSpringDataAuditable。

使用Javers依赖项

 <dependency>
                <groupId>org.javers</groupId>
                <artifactId>javers-spring-jpa</artifactId>
                <version>5.7.0</version>
            </dependency>

sqlSchemaManagementEnabled开关由JaVers Spring Boot启动程序管理，请参见https://javers.org/documentation/spring-boot-integration/

如果您不使用启动器，则不会读取该开关，但是仍然可以在构建Javers实例时设置此开关：

        def javers = JaversBuilder.javers()
                .registerJaversRepository(sqlRepository()
                .withConnectionProvider({ DriverManager.getConnection("jdbc:h2:mem:empty-test") } as ConnectionProvider)
                .withSchemaManagementEnabled(false)
                .withDialect(getDialect())
                .build()).build()
