【问题描述】：

您好，我正在使用带有 Spring Boot 2.3.5.RELEASE 版本的 MongoDB 事务功能。我收到以下异常。我正在用控制器类编写集成测试。

下面给出的例外。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.app.cat.resource.Test0': Unsatisfied dependency expressed through field 'controller'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.dell.pde.resources.NVTValidationCategoryController' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:643) ~[spring-beans-5.2.10.RELEASE.jar:5.2.10.RELEASE]
    at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:130) ~[spring-beans-5.2.10.RELEASE.jar:5.2.10.RELEASE]
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPost

我在下面提供代码sn-p。

@Profile("test")
@ActiveProfiles("test")
@DataMongoTest(excludeAutoConfiguration = MongoDBTxnConfiguration.class)
@Import(TestMongoConfig1.class)

@EnableAutoConfiguration(exclude={ SecurityAutoConfiguration.class, DataSourceAutoConfiguration.class, RedisAutoConfiguration.class,
    RedisRepositoriesAutoConfiguration.class,  
    SecurityFilterAutoConfiguration.class, SecurityAutoConfiguration.class })

@SpringBootApplication(scanBasePackages = {"com.app.cat"})
public class Test0 {
    
    @Autowired
    private CategoryController controller;
    
    @Autowired
    @Qualifier("validations")
    private ValidationService vldnService;
    
    @Test
    void testAllValidationsBeforeEntry() {
        System.out.println("controller : " + vldnService);
        assertEquals(true, true);
    }
}

请指导我做错了什么。请帮帮我。

【解决方案1】：

@DataMongoTest 注解也使用@AutoConfigureDataMongo、@ImportAutoConfiguration。如果您提供自动配置的类，它将发生冲突。您必须使用@DataMongoTest 排除其他要加载和运行的类。因为它是一个测试类，所以不要使用@SpringBootApplication(scanBasePackages = {"com.app.cat"})。最后我提供了可能对你有帮助的位码sn-p。

@DataMongoTest(excludeAutoConfiguration = {SecurityAutoConfiguration.class, 
        SecurityFilterAutoConfiguration.class, 
        SecurityAutoConfiguration.class, ... <any other configuration>})
@Profile("test")
@ComponentScan(basePackages = {"com.app.cat"}, excludeFilters={
          @ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, 
                  value= {MongoDBTxnConfiguration.class,SecurityCloudConfig.class})})

public class Test {
    @Autowired
    private YourControler ctrlr;
    
    
    @Test
    void test1() {
        // Logic for testing
    }
}
