springBoot-cloud的错误

报错如下:

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).

错误产生原因:

公共工程下使用了数据库,而其他工程引入公共工程时,未添加相关依赖和数据库链接信息

解决示例:

 
	 com.baomidou
	 mybatis-plus-boot-starter
	 ${mybatisplus.version}



	mysql
	mysql-connector-java
	8.0.23

# 配置数据库相关链接
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/bill-manager
    username: root
    password: root
