Java Junit测试和spring@配置中的自动连线失败

我有两个

@Configuration

类。我需要一个从一个配置类到另一个配置类的bean。我已将配置1自动连接到2。一切正常。当执行单元测试时，我得到以下异常

setUpContext(com.trafigura.titan.framework.services.messaging.loader.SpringLoadTest)
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.xxx.MessagingServicesConfig': Injection of autowired dependencies failed; 
nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.xxx.EMSJMSConfig com.xxx.MessagingServicesConfig.emsJmsConfig; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type[com.xxx.EMSJMSConfig] 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)}

还有什么我需要做的额外工作，使这个工作

下面是测试的设置

@Configuration
@Import({MessagingServicesConfig.class,...,EMSJMSConfig.class
})
public class MessagingConfig {}

@Profile("EMS-MESSAGING")
@Configuration
public class EMSJMSConfig {
    @Bean
    public javax.jms.ConnectionFactory jmsSubscriberConnectionFactory() throws JMSException {
        SingleConnectionFactory singleConnectionFactory = new SingleConnectionFactory(tibjmsConnectionFactory());
        return singleConnectionFactory;
    }
}

@Configuration
public class MessagingServicesConfig {
    @Autowired
    private EMSJMSConfig emsJmsConfig;
    @Bean(destroyMethod = "shutdown")
    public MessagingService messagingService() throws JMSException {
        ...
        ConnectionFactory cf=emsJmsConfig.jmsSubscriberConnectionFactory(); // Getting NPE at this line.
    }
}

最后是测试类

public class MessagingServicesConfigTest {
    private MessagingServicesConfig config;
    private EMSJMSConfig emsJmsConfig;
    @BeforeMethod
    public void setUp() throws Exception {
        config = new MessagingServicesConfig();
        ... //what needs to be done here to have the EMSJMSConfig
    }
    @Test
    public void testBuildsCorrectService() throws JMSException {
        MessagingService service = config.messagingService();   
        ...
    }
}

通过调用

new

您自己正在创建对象，Spring对此一无所知

此外，您应该有一个测试配置，它将知道您的bean

使用适当的

Runner

加载

SpringContext

@ContextConfiguration(classes = TestConfig.class)
@RunWith(SpringRunner.class)
class Tests {

    @Autowired // if needed
    private MessagingServicesConfig config;
}

在

TestConfig

中，您可以创建

bean

或从应用程序导入配置：

@Configuration
@Import({MessagingServicesConfig.class})
public class TestConfig {}

@Configuration
@Import({EMSJMSConfig.class})
public class MessagingServicesConfig {}

或者，您可以直接参考配置类：

@ContextConfiguration(classes = {MessagingServicesConfig.class, EMSJMSConfig.class})

这不会有帮助，也不会加载配置。使用适当的

@ContextConfiguration

注释指定要加载的内容。然后请告诉我如何加载它？如果看不到您现在正在做什么，很难判断。但是您应该使用

SpringRunner

来运行测试，并使用

@ContextConfiguration

来指定要加载的类。如果没有

@ContextConfiguration

，这将不会有多大作用（我怀疑会发出警告和错误）。@M.Deinum，我的坏，发布不完整。
