Spring Boot@SpringBootTest给出了noClassDefFounderRor:...DataAccessException

Question

我无法解决这个问题。我有一个spring boot应用程序。

用

@SpringBootApplication.

使用以下注释的测试类：

@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() {
    }
}
