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).

我的项目环境:
springcloud+Nacos+mybatisPlus
解决形式:
搜寻解决形式, 有网友说是: 在多模块的 maven 我的项目中 springboot 没有读到配置文件造成的,所以只用在此模块的最外层 pom 文件中增加 <build> … </build> 配置, 应用后并不失效.
排查 N 久后发现, 在 nacos 中, 导入其余我的项目的残缺配置文件后 我的项目是能够失常启动的,证实是配置文件的问题!!!!!! 删除与以后模块无关的配置文件后, 发现, 以后子模块的配置的 nacos 分组是本人设置的个性化分组, 而不是默认的 ”DEFAULT_GROUP”,
在以后我的项目的 .yml 文件中并没有指定以后应用的分组是个性化分组:
nacos 配置:
批改 yml 文件:
重启, 失效!!!!!
也能够通过 注解形式 实现:
在启动类上减少注解:
@SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
须要留神 : 应用注解还要把 allow-bean-definition-overriding 的值设为 true
spring.main.allow-bean-definition-overriding=true
如果不失效, 能够试试手写的:
public static void main(String[] args) {SpringApplication app = new SpringApplication(TestApplication.class);
app.setAllowBeanDefinitionOverriding(true);
app.run(args);
}
