我是 spring-boot 的新手。因此,在从 spring initializr 引导一个项目之后,我试图在 intellij 上运行它。但是我在启动时遇到错误。
以下是版本:
Java : 8
Spring 启动:2.0.6
我曾尝试更改 spring boot 版本,但没有帮助。
还更改了 application.properties 中的服务器端口,但这也没有帮助。

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

最佳答案
由于您尚未向此项目添加任何数据库,因此请从您的 pom.xml 文件中删除 data-jpa
依赖项,
它造成了依赖冲突。
删除后它将正常运行。
关于启动 tomcat 上下文的 Spring-boot 错误。创建名称为 'servletEndpointRegistrar' 的 bean 时出错,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/54721530/
