spring-boot - liquibase升级到3.2.2后单元测试打印异常

Question

我有一个 spring boot/liquibase 应用程序，在将 liquibase 升级到 3.2.2 后，单元测试开始打印此异常，但测试仍然通过:

Answer 1

Spring Boot 目前不支持 Liquibase 3.2.2。我没有看到您在问题中发布的确切错误，但我怀疑这是 Liquibase 3.0.x 和 3.2.x 之间不兼容的另一个症状。

为了安全起见，您现在应该坚持使用 Liquibase 3.0.x，尽管我相信 3.1.x 也可以。

有一个开放的Spring Boot issue描述 3.2.x 的一些问题。还有一个开放的Spring Boot pull request提供与 Liquibase 3.2.x 的兼容性。它计划包含在将于 11 月发布的 Spring Boot 1.2 中。
