测试运行：1，失败：0，错误：1，跳过：0，所用时间：0.547 s为什么在新项目中执行此操作而不是使用现代标准的Spring Boot？是的。我学的是没有springboot的spring，别这样。Spring Boot的发明就是为了避免这种情况的发生，它已经成为标准产品好几年了。这些错误通常来自于这样一个事实，即混合了来自不同Spring版本的罐子。检查您的依赖关系。另外，您的@Configuration
注释类也有缺陷，不要捕获异常，而是让Spring处理它们（否则您的应用程序将处于非法状态），并且您正在数据源方法中泄漏连接（如果您执行getConnection
您也应该关闭它），而且它也不会测试任何东西，所以请将其删除。
