运行 使用@SpringApplicationConfiguration 的多模块项目中域的测试抛出NoSuchBeanDefinitionException?

Running domain's tests in multi-module project with @SpringApplicationConfiguration throws NoSuchBeanDefinitionException?

我的多模块项目结构如下:

project-example (parent)
-- project-example-domain: contains DAOs and Services
-- project-example-service: contains Controllers

服务模块将域作为依赖项,因此服务知道域,但反之则不然。

所以,为了测试 ClientDAO 的完整性(在本例中),我有这个测试:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = DAOConfiguration.class)
public class ClientDAOTests {

    @Autowired
    private ClientDAO dao;

    @Test
    public void testFindClient() {
          ...
    }

}

当我 运行 它时,我得到这个异常:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] 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)}
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1301)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1047)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:942)
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:533)
    ... 51 more

最后是我的 DAOConfiguration

@Configuration
@PropertySource("classpath:persistence.properties")
@EnableJpaRepositories(basePackages = {"com.example.movies.domain.feature"})
@EnableTransactionManagement
public class DAOConfiguration {

    @Autowired
    private Environment env;

    @Autowired
    private DataSource dataSource;

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder) {
        LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
        entityManager.setDataSource(this.dataSource);
        entityManager.setPackagesToScan(new String[] {"com.example.movies.domain"});
        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        entityManager.setJpaVendorAdapter(vendorAdapter);
        return entityManager;
    }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);
        return transactionManager;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }

}

当我 运行 来自服务的服务器工作正常时,Spring 生成 DataSource bean。但是当我 运行 我在域中进行测试时,我得到了前面提到的异常。

所以我认为我的问题是我将不正确的参数传递给@SpringApplicationConfiguration。我不明白我必须传递什么...我应该将带有 @SpringBootApplication 注释的 Application class 传递给它吗?在这种情况下,这是在服务模块内部,所以域不知道这个 class。您能解释一下 SpringApplicationConfiguration 应该将什么作为参数使我的测试失败吗?提前致谢!


编辑

这是我的 ApplicationRunner class 位于服务层:

@SpringBootApplication
@Import({ServicesConfiguration.class, CustomDataBindingConfiguration.class, CustomMappingConfiguration.class})
@PropertySource(value = {"application.properties"})
public class ApplicationRunner {

    public static void main(String[] args) {
        SpringApplication.run(ApplicationRunner.class, args);
    }

}

我解决了同样的问题。

问题来自@SpringApplicationConfiguration(classes = DAOConfiguration.class)。 您必须引用带有 @EnableAutoConfiguration 注释的 class,以便 Spring Boot 自动注入数据源。 (这个注解一般继承自@SpringBootApplication

您有多种选择:

  • 引用您的应用程序 class,并在 @SpringApplicationConfiguration

  • 中用 @SpringBootApplication 注释
  • @EnableAutoConfiguration添加到DAOConfigurationclass

  • ...(你懂的)
