其实我是Spring-boot概念的新手，我的问题是当我在eclipse中运行我的程序时我得到了如下所示的错误，问题是我得到了错误是什么以及如何解决这个问题。 ，所以有人帮我解决了这个错误

有很多堆栈跟踪可供查看，无需调试代码。但是对我来说突出的一个部分就是说＆＃34;如果你想要一个嵌入式数据库，请在类路径上放一个支持的数据库。＆＃34;。
因为您只共享堆栈跟踪而没有代码，所以我只能推测发生了什么，但看起来好像需要数据源，但是无法创建，因为类路径上没有合适的嵌入式数据库库（如H2，Hypersonic或Derby）。我无法肯定地说，但我相信关于设置Spring Security过滤器的部分只是没有数据源的副作用。
但是，再次，不知道是什么，如果你配置了任何bean（Boot是在做所有的autoconfig还是你明确配置了任何bean？）我只能指出数据源错误。
