Failed to configure a DataSource: 'url' attribute is not specified spring boot3.0启动时候报错

 spring boot的配置文件名由application.yml改为bootstrap.yml或者bootstrap.properties

报错：

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

然后在启动类加了后仍然报错

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

报错：

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

 

我使用的是spring boot3.0，原因是需要在pom中添加如下，并且启动类去掉exclude = DataSourceAutoConfiguration.class

<!--如果配置文件是bootstrap.properties，必须的加这个-->
