【问题描述】：

我想使用活动配置文件“firza”运行我的项目，但它给了我以下错误。在谷歌上搜索后，我尝试了所有可能的修复，但没有任何效果：| 有谁能够帮我？

application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/MySportsAcademy?createDatabaseIfNotExist=true
spring.datasource.username=admin
spring.datasource.password=ivl123
spring.data.rest.basePath=/api

        </dependency>

错误

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

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "firza" are currently active).

【问题讨论】：

如果不存在也添加这个依赖：org.springframework.bootspring-boot-starter-data-jpa

spring.datasource.driver-class-name=com.mysql.jdbc.Driver 在 application-firza.properties 中丢失

@Afridi 已经在场

@Chids 它没有任何区别..错误仍然存​​在：|

在您的主应用程序类中添加这一行：@EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class) 检查：journaldev.com/13830/…

【参考方案1】：

确保资源文件夹中有 application.properties 和所需的数据库参数

这里是例子

spring.datasource.platform=mysql
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://vaquarkhan.com:3307/vk01?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=xyz
spring.datasource.password=xyzwe
spring.datasource.initialization-mode=never
#spring.datasource.schema=schema.sql
logging.level.org.springframework.integration=DEBUG
