第二次生成"JHipster-UML"

Question

我正在尝试使用 "JHipster-UML"。我第一次运行它在我的 xmi 文件中运行良好。然后我修改了我的模式（使用 GenMyModal），导出并在修改后的 xmi 文件上重新运行 "JHipster-UML" 然后重新启动。然后我在启动时出错。我错过了一步吗？

Exception in thread "main" org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.boot.context.embedded.EmbeddedServletContainerException: Unable to start embedded Tomcat

原因：

Answer 1

我想你没有在开发模式下使用 H2 数据库，所以这意味着数据库更改被持久化并且 Liquibase 发现你的更改日志的校验和与之前运行和中记录的不同这是正确的。如果你想克服这个问题，你必须删除你的架构并重新启动应用程序。

当然，在开发中使用H2就没有这些问题了
