我计划使用Cassandra来React式地保存数据。为此，我编写了以下接口：

@Repository
public interface ContributorStatRepository extends ReactiveCrudRepository<ContributorStat, Long> {
    Flux<ContributorStat> findByAkonId(String akonId);
}

上面的异常被抛出：

com.example.sample.controller.ContributorStatControllerTest > shouldReturnBadRequestWithBlankContributorStat FAILED
    java.lang.IllegalStateException
        Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException
            Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException
                Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException

• • 你知道为什么没有为ContributorStatRepository创建合适的bean吗？**

我正在使用Spring boot 2.0.0.M7和这些依赖项：

dependencies {
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('javax.xml.bind:jaxb-api:2.3.0')
    compile('org.springframework.boot:spring-boot-starter-webflux')
    compile('org.springframework.boot:spring-boot-starter-data-cassandra-reactive')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('io.projectreactor:reactor-test')
}

• • 更新**：运行测试：

@Test
public void shouldReturnBadRequestWithBlankContributorStat() throws Exception {
    requestPayload = mapper.writeValueAsString(new ContributorStatDTO());

    this.mockMvc.perform(post(CONTRIBUTOR_STATS_ROUTE)
            .contentType(MediaType.APPLICATION_JSON)
            .accept(MediaType.APPLICATION_JSON)
            .content(requestPayload)).andDo(print())
            .andExpect(status().isBadRequest());
}
