启动ApplicationContext时出错。创建bean时出现问题

Question

我也有同样的问题。在从书中学习 Java Spring 时，当我将数据库连接到我的应用程序时，我遇到了错误：

Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

之前Sql出现了问题，但她似乎能够通过mySql和DBNavigator连接数据库，但同样一切都没有按计划进行。这是我的 pom：

Answer 1

根据错误信息，似乎

schema.sql

中的sql初始化脚本为空或丢失。因此，如果您确定要运行初始化脚本，请确保指定其位置并正确填写。或者，如果您不愿意运行初始化，您可以在配置文件中将其关闭。
