Spring Boot 的 Flyway 迁移错误详细信息

Question

我们有一个使用 Spring Boot 和 Flyway 的项目。

当我们运行失败的迁移且日志级别全部设置为 DEBUG 时，我们只收到以下消息：

[DEBUG] org.flywaydb.core.internal.command.DbValidate - Validating migrations ...
[DEBUG] org.flywaydb.core.internal.scanner.Scanner - Filtering out resource: db/migration/V1/V1_202103081030__account.sql (filename: V1_202103081030__account.sql)

[INFO ] org.apache.catalina.core.StandardService - Stopping service [Tomcat]

Caused by: org.flywaydb.core.api.exception.FlywayValidateException: Validate failed: Migrations have failed validation

没有关于失败原因的更多详细信息（失败的查询、不匹配的校验和……）。

我查看了spring.flyway应用程序属性，但发现没有任何帮助。

我们应该怎么做才能在服务器启动时在日志中显示 Flyway root 错误？

编辑：要明确的是，问题不是失败本身（在 Flyway 类中设置断点可以揭示源错误）。问题是日志中缺少错误详细信息。

Answer 1

我遇到了同样的问题，发现它与我使用的 Flyway 版本有关（Spring Boot 2.4.3，它使用 Flyway 7.1.1）。这是一个已知问题2987 - 在异常中显示所有验证消息，已在 Flyway 7.2.0中修复。

他们建议将运行flyway validate -outputType=json作为解决方法来获取详细的错误消息。我尝试了，但仍然没有收到详细的错误消息。

对我有用的解决方案是通过在我的 pom 文件中指定版本来升级到 Flyway 7.2.0：

<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-core</artifactId>
    <version>7.2.0</version>
</dependency>
