MappingMongoConverter 不可用于使用 @EnableMongoAuditing 进行单元测试的自动装配

Question

我有一个 Spring Boot 应用程序，我在其中启用了 mongo 审核。应用程序启动正常，并存储带有所有审核字段（createdDate、updatedDate 等）的 mongo 文档。但是，在运行单元测试时，出现以下异常：

java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoAuditingHandler': Cannot create inner bean '(inner bean)#115c946b' of type [org.springframework.data.mongodb.config.MongoAuditingRegistrar$MongoMappingContextLookup] while setting constructor argument; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '(inner bean)#115c946b': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.data.mongodb.core.convert.MappingMongoConverter' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '(inner bean)#115c946b': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.data.mongodb.core.convert.MappingMongoConverter' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.data.mongodb.core.convert.MappingMongoConverter' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

这是我的主要课程

@SpringBootApplication
@EnableMongoAuditing
public class TestApplication {
    public static void main(String[] args) {
        SpringApplication.run(PatientstoreApplication.class, args);
    }
}

这是我的测试课：

@WebMvcTest(TestController.class)
public class TestTest {
    @Autowired MockMvc mockMvc;
    @MockBean TestService testService;

    @Test
    public void test() {

    }
}

我的问题是：是否缺少任何配置？我应该为我的测试用例手动创建 MappingMongoConverter 类型的 bean 吗？

Answer 1

我遇到了同样的情况。

在您的@WebMvcTest班级中，尝试添加测试配置，例如：

    @TestConfiguration
    static class TestConfig {
        @Bean
        public MappingMongoConverter mongoConverter() {
            return new MappingMongoConverter(mock(DbRefResolver.class), mock(MappingContext.class));
        }
    }
