Spring Boot@SpringBootTest给出了noClassDefFounderRor:…DataAccessException

Question

@SpringBootApplication.

@RunWith(SpringRunner.class)
@SpringBootTest

@Configuration
public class YadaYadaFilterConfigurer
{
    @Bean
    public FilterRegistrationBean<YadaYadaFilter> createYadaYadaFilter() 
    {...}

    ...
}

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.web.servlet.FilterRegistrationBean]: 
...
nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: URL [jar:file:...org.springframework.boot/spring-boot-test-autoconfigure/2.0.6.RELEASE/b0eb15474e795850dfa59b01ee6a83d7a39e3645/spring-boot-test-autoconfigure-2.0.6.RELEASE.jar!/org/springframework/boot/test/autoconfigure/jdbc/JdbcTest.class]; nested exception is java.lang.NoClassDefFoundError: org/springframework/dao/DataAccessException

dependencies {
    implementation('org.springframework.boot:spring-boot-starter-web')
    testImplementation('org.springframework.boot:spring-boot-starter-test')
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class JsonvalidationApplicationTests {

    @Test
    public void contextLoads() {
    }
}

原因：org.springframework.beans.beanInstantiationException：无法实例化[org.springframework.boot.web.servlet.FilterRegistrationBean]:工厂方法“Createyadayada Filter”引发异常；嵌套异常是org.springframework.beans.factory.beanDefinitionStoreException:未能读取候选组件类:URL[jar:file://c://users/66122872/.gradle/caches/modules-2/files-2.1/org.springframework.boot/spring-boot-test-autoconfigure/2.0.6.release/b0eb15474e795850dfa59b01ee6a83d7a39e3645/spring-boot-test-autoconfigure-2.0.6.嵌套异常是java.lang.noClassDeFounderRor：org/springframework.beans.factory.support.simpleInstantiationStrategy.Instantiate（SimpleInstantiationStrategy.java:185)在org.springframework.beans.factory.support.ConstructorResolver.InstantiateUsingFactoryMethod(constructorResolver.java:583)...67更多原因是：.1/org.springframework.boot/spring-boot-test-autoconfigure/2.0.6.release/b0eb15474e795850dfa59b01ee6a83d7a39e3645/spring-boot-test-autoconfigure-2.0.6.release.jar！/org/springframework/boot/test/autoconfigure/jdbctest.class]；嵌套异常是java.lang.noClassDefFounderRorr：org/springframework/dao/dataAccessException

Answer 1

对不起，经过进一步的调查，我发现问题出在我的FilterRegistrationBean上。

exeption被扔到这里。

ClassPathScanningCandidateComponentProvider provider = createComponentScanner();
provider.findCandidateComponents("").stream()...

我将回答这个线程，并创建一个新的。
