Spring Boot错误启动tomcat上下文创建名称为“ servletEndpointRegistrar”的bean时出错

如何解决Spring Boot错误启动tomcat上下文创建名称为“ servletEndpointRegistrar”的bean时出错

由于您尚未向该项目中添加任何数据库，因此data-jpa从pom.xml文件中删除了依赖项， 这在创建依赖项冲突。 删除后它将正常运行。

解决方法

我是SpringBoot的新手。因此，在从spring initializr启动项目后，我试图在intellij上运行它。但是启动时出现错误。

以下是 版本 ：
Java：8
Spring-boot：2.0.6
我尝试更改Spring Boot的版本，但没有帮助。
还更改了application.properties中的服务器端口，但这也无济于事。

   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).
