我有一个spring启动应用程序，它的文件层次结构：

src/
└── main/
    └── java/
    |      ├── com.example/
    |      |         ├── config/ 
    |      |         |     └──R2DBCConfiguration.java
    |      |         ├── dao/
    |      |         |     └── UnitR2DBCRepository.java
    |      |         └── R2DBCApplication.java
    |      └──resources/
    |             └── application.yml
    └── test
        └── java/
               ├── com.example/
               |         └── dao/
               |               └── R2DBCTest.java
               └──resources/
                      └── application.yml

r2dbcconfiguration.java文件

@Configuration
@AllArgsConstructor
public class R2DBCConfiguration {
    @Bean
    public ConnectionFactory connectionFactory() {
        return new PostgresqlConnectionFactory(PostgresqlConnectionConfiguration.builder(). ... .build());
    }

    @Bean
    public DatabaseClient databaseClient() {
        return DatabaseClient.builder().connectionFactory(connectionFactory()).build();
    }
}

unit2rdbcrepository.java文件

@Repository
public interface UnitR2DBCRepository extends ReactiveCrudRepository<Unit, UUID> { }

r2dbcaplication.java文件

@SpringBootApplication
public class R2DBCApplication{
    public static void main(String... args) {
        SpringApplication.run(R2DBCApplication.class, args);
    }
}

测试.java

@SpringBootTest
@ContextConfiguration(classes = R2DBCConfiguration.class)
public class R2DBCTest {

    @Autowired
    private DatabaseClient client;
    @Autowired
    private UnitR2DBCRepository unitR2DBCRepository;

    @Test
    public void test() {
        ...
    }
}

运行r2dbctest时，出现错误：
nosuchbeandefinitionexception:没有类型为“com.example.dao.unitr2dbcRecepository”的限定bean可用：至少需要1个符合autowire候选的bean。依赖项注解：{@org.springframework.beans.factory.annotation.autowired（required=true）}
