springboot从2.3.9升级到2.6.3后遇到错误

Question

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

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: {}
    

升级后的一项观察，

spring-boot-test jar 中的ConfigFileApplicationContextInitializer类被修改为ConfigDataApplicationContextInitializer。

Answer 1

是的，这是一个法律假设，事实也是如此。实际上，在 spring-boot 2.4.0 中，ConfigFileApplicationContextInitializer 已经被标记为 deprecated，取而代之的是ConfigDataApplicationContextInitializer。请注意，ConfigFileApplicationContextInitializer从 3.0.0 开始，它不再存在于 spring-boot 中。
所以你可以切换到ConfigDataApplicationContextInitializer这应该足够了。
