我跟随这个链接用spring数据实现r2dbc。该项目有巨大的pom，因为它演示了其他功能。所以我试着只依赖spring引导和r2dbc与h2。
我的pom是：

            <artifactId>spring-boot-starter</artifactId>

        <!---->
<dependencies>

我将存储库定义为：

public interface ReactiveFeatureRepository extends ReactiveCrudRepository<Feature, UUID> {
}

要素是实体类。
我在src/test/resources的application.properties中配置了h2：

spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:db;DB_CLOSE_DELAY=-1
spring.datasource.username=sa
spring.datasource.password=sa

试验中：

@ExtendWith(SpringExtension.class)
@SpringBootTest
public class ReactiveFeatureRepositoryTest {

    @Autowired
    ReactiveFeatureRepository rfr;

    @Autowired
    DatabaseClient client;

    @Autowired
    H2ConnectionFactory factory;
...
...
}

但是当我尝试运行测试时，我得到了大量的日志，其中列出了“积极匹配”和“消极匹配”，最后：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 
'x.y.z.ReactiveFeatureRepositoryTest': Unsatisfied dependency expressed 
through field 'rfr'; nested exception is 
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 
'x.y.z.ReactiveFeatureRepository' available: expected at least 1 bean which 
qualifies as autowire candidate. Dependency annotations: 
{@org.springframework.beans.factory.annotation.Autowired(required=true)}
    at

与示例项目相比，我缺少什么？
