无法将 MapStruct 映射器注入 spring-boot JUnit 测试中

Question

我正在尝试使用componentModel="spring"为 MapStruct 映射器编写单元测试。

该应用程序运行良好，包括映射器注入。 问题是映射器没有注入到测试类，我收到以下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.onap.sdc.workflow.api.mapping.WorkflowMapperTest': Unsatisfied dependency expressed through field 'workflowMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.onap.sdc.workflow.services.mappers.WorkflowMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

我正在使用智能IDEA和目标\生成源被标记。

下面是映射器类：

@Mapper(componentModel = "spring")
public interface WorkflowMapper {
@Mapping(source = "properties", target = "category", qualifiedByName = "propertiesToCategoryMapper")
Workflow itemToWorkflow(Item item);
@Mapping(source = "category", target = "properties", qualifiedByName = "categoryToPropertiesMapper")
@InheritInverseConfiguration
Item workflowToItem(Workflow workflow);
@Named("propertiesToCategoryMapper")
default String customPropertiesToCategoryMapper(Map<String, Object> properties) {
return String.class.cast(properties.get(WorkflowProperty.CATEGORY));
}
@Named("categoryToPropertiesMapper")
default Map<String, Object> customCategoryToPropertiesMapper(String category) {
return Collections.singletonMap(WorkflowProperty.CATEGORY, category);
}

我在以下代码片段中使用此映射器：

@Service("workflowManager")
public class WorkflowManagerImpl implements WorkflowManager {
private WorkflowMapper workflowMapper;
@Autowired
public WorkflowManagerImpl(WorkflowMapper workflowMapper) {
this.workflowMapper = workflowMapper;
}
...some code

单元测试类：

@ContextConfiguration(classes = 
WorkflowMapperTest.WorkflowMapperSpringTestConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class WorkflowMapperTest {
@Configuration
@ComponentScan(basePackageClasses = WorkflowMapperTest.class)
public static class WorkflowMapperSpringTestConfig { }
@Autowired
WorkflowMapper workflowMapper;
@Test
public void shouldMapItemPropertyToWorkflowCategory() {
...some code...
}

任何帮助将不胜感激。

一目了然，您没有将要测试的 Bean 作为组件扫描的一部分包括在内。

您需要更新@ComponentScan配置以包含它。

@ComponentScan(basePackageClasses = {WorkflowMapperTest.class,
WorkflowMapper.class,
WorkflowMapperImpl.class})
