问题描述

我尝试连接springboot；当我运行时，出现错误“Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured."”

application.yml 应用程序.yml

datasource:
    druid:
      driver-class-name: com.mysql.cj.jdbc.driver
      url: jdbc:mysql://localhost:3306/dbName
      username: root
      password: ********(pass)

Output 输出

***************************
APPLICATION FAILED TO START
***************************

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).

解决方案

删除application.yml中的druid

datasource:
      driver-class-name: com.mysql.cj.jdbc.driver
      url: jdbc:mysql://localhost:3306/dbName
      username: root
      password: ********(pass)
