如何在Spring Boot的集成测试中自动连接存储库？

Question

我正在尝试编写集成测试，但在测试中自动装配存储库时遇到问题。

我收到此异常： org.springframework.beans.BeanInstantiationException：无法实例化[org.observer.media.repository.ArticleRepository]：指定的类是一个接口。

编辑： 我在@EnableJpaRepositories中添加了PersistenceConfig.class，代码如下。这导致异常org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available

我也尝试添加Application.class在@SpringBootTest（类= {}在包罗万象的尝试，但抛出Error creating bean with name 'articleRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class org.observer.media.model.Article

ScraperRunnerIntegrationTest（在配置类仅包含域类的豆） ：

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringBootTest(classes = { 
     ApplicationConfig.class, 
     PersistenceConfig.class, 
     DeMorgenTestConfig.class, 
     Article.class, 
     ScraperRunner.class, 
     DeMorgenWebsiteScraper.class, 
     ArticleService.class, 
     DeMorgenPageScraper.class, 
     JsoupParser.class, 
     DeMorgenArticleScraper.class, 
     GenericArticleScraper.class, 
     ImageMetaScraper.class, 
     ArticlePrinter.class, 
     ArticleRepository.class 
}) 
public class ScraperRunnerIntegrationTest { 

    private final static Article EXPECTED_ARTICLE_1 = anArticle().withHeadline("headline1").build(); 
    private final static Article EXPECTED_ARTICLE_2 = anArticle().withHeadline("headline2").build(); 

    @Autowired 
    private ScraperRunner scraperRunner; 
    @Autowired 
    private DeMorgenWebsiteScraper deMorgenWebsiteScraper; 

    @Autowired 
    private ArticleRepository articleRepository; 

    @Test 
    public void run() { 
     scraperRunner.run(deMorgenWebsiteScraper); 

     assertThat(articleRepository.findAll()).containsOnly(EXPECTED_ARTICLE_1, EXPECTED_ARTICLE_2); 
    } 

库：

import org.observer.media.model.Article; 
import org.springframework.data.jpa.repository.JpaRepository; 
import org.springframework.data.jpa.repository.Query; 
import org.springframework.data.repository.query.Param; 
import org.springframework.stereotype.Repository; 

import java.util.List; 

@Repository 
public interface ArticleRepository extends JpaRepository<Article, Long> { 

    List<Article> findAll(); 

    Article findByHash(String hash); 

    Article findByHeadline(String headline); 

    List<Article> findArticleByHeadlineAndCompanyName(String headline, String companyName); 

    @Query("SELECT CASE WHEN COUNT(a) > 0 THEN true ELSE false END FROM Article a WHERE a.hash = :hash") 
    boolean existsByHash(@Param("hash") String hash); 
} 

PersistenceConfig.class：

package org.observer.media.config; 

import org.springframework.context.annotation.Configuration; 
import org.springframework.data.jpa.repository.config.EnableJpaRepositories; 

@Configuration 
@EnableJpaRepositories("org.observer.media.repository") 
public class PersistenceConfig { 
} 

Answer 1

您只需提供类别，注释为@Configuration至@SpringBootTest。

我已将原始示例从here修改为使用@SpringBootTest注释。 所以下面的配置工作：

@Configuration 
@ComponentScan("hello") 
public class AppConfig { 

} 

注意@ComponentScan注解。 然后在我的测试：

@RunWith(SpringRunner.class) 
@SpringBootTest(classes={AppConfig.class}) 
public class CustomerRepositoryTests { 
    @Autowired 
    private CustomerRepository customerRepository; 
} 

它做到了一招。你可以尝试在你的例子中做同样的事情。
