Question

我正在尝试执行集成测试，并且我的带有@Transactional注释的类无法自动连接到具有NoSuchBeanDefinitionException的测试类。我评论了它并检查了加载的bean列表，我的服务就在那里，只是没有注入。

org.springframework.beans.factory.BeanCreationException：创建名为“com.icsynergy.scim.service.DBIntegrationServiceTest”的bean时出错：注入自动连接的依赖项失败;嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配字段：private com.icsynergy.scim.service.DBIntegrationService com.icsynergy.scim.service.DBIntegrationServiceTest._service;嵌套异常是

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.icsynergy.scim.service.DBIntegrationService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

如果删除此注释，则会注入，但没有事务支持。

这是我的班级

@Slf4j
@Service(value = 'integrationService')
@EnableConfigurationProperties(DBIntegrationConfig.class)
//@Transactional
class DBIntegrationService implements IntegrationService, HealthIndicator {...

我尝试将其注入

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
class DBIntegrationServiceTest {

@Autowired
DBIntegrationService _service
...

以下是Application.class

@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = [
    "com.icsynergy.scim.repository",
    'com.icsynergy.scim.service',
    "com.icsynergy.scim.web",
    "com.icsynergy.scim.config"
], excludeFilters = [
    @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value =   OktaSCIMService.class),
    @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = DBIntegrationService.class)
])
@ImportResource("config.xml")
@EnableTransactionManagement
public class Application { 
....

这是来自config.xml的片段

<bean name="integrationService" class="com.icsynergy.scim.service.DBIntegrationService"/>

<bean name="service" class="com.icsynergy.scim.service.OktaSCIMService">
    <property name="service" ref="integrationService"></property>
    <property name="implementedUserManagementCapabilities">
        <list value-type="com.okta.scim.server.capabilities.UserManagementCapabilities">
            <value>GROUP_PUSH</value>
        </list>
    </property>
</bean>

编辑：找到了解决方法。由于我的服务实现了IntegrationService，因此注入它实际上有助于避免异常。仍然不明白我的原始注射有什么问题

将欣赏任何想法，TIA

你最好使用接口而不是具体的类，所以你应该像这样编写代码：

@Autowired
IntegrationService _service

如果您没有界面，则应创建一个。

@Transactional带注释的类无法自动装配
