从springboot 2.3.9升级到2.6.6后，我的测试失败，出现以下错误：

java.lang.AssertionError: 
Expecting:
 <Unstarted application context org.springframework.boot.test.context.assertj.AssertableApplicationContext[startupFailure=org.springframework.beans.factory.UnsatisfiedDependencyException]>
to have a single bean of type:
 <com.air.dx.range.application.RangeApplicationService>:
but context failed to start:
 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'IRoRangeRepository': Unsatisfied dependency expressed through method 'setDialect' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.data.relational.core.dialect.Dialect' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

字符串
升级后的一个观察，
spring-boot-test jar中的类ConfigFileApplicationContextInitializer修改为ConfigDataApplicationContextInitializer。
