启动Spring Boot应用程序时liquibase出现问题

Question

我有一个Spring Boot应用程序与liquibase，我第一次创建表没有问题，但当我再次启动它时，我有一个我无法解决的问题。

这是错误：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2021-03-21 12:22:27.294 ERROR 8828 --- [           main] o.s.boot.SpringApplication               : Application run failed

我尝试了以下方法，但未能解决问题：

-

-

<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>8.0.22</version>
</dependency>

-

但我试过的方法都没有解决这个问题。我如何解决这个问题才能顺利启动应用程序？

Answer 1

这是Spring Boot 2.4.3的一个已知问题。过来看：https://github.com/liquibase/liquibase/issues/1639

您可以使用Spring Boot 2.4.2（我就是这么做的），也可以将Liquibase更新到4.3.1版。

<dependency>
    <groupId>org.liquibase</groupId>
