@集成测试中的@Autowired and UnsatisfiedDependencyException

问题描述 投票：0回答：1

我有一个带有Spring Boot和外部服务器Weblogic的多模块项目。

这些是模块：

  • dao
  • 服务

  • web

    pom.xml（dao）。

这是数据库（存储库，实体）的工作

    这是处理来自客户端（Contoroller和RestControllers）的请求的工作。

应用程序中有一个入口点。

进入Web模块是test-dir。

  • src / test / java / com / web

这里是存储库

  • src / test / java / com / web / dao / repository / company / CompanyReadRepositoryTest.java
public interface CompanyReadRepositoryTest extends CrudRepository<Company, Long> {

    String nameTable = "company";
    String lastEntryQueryFor =
            "select * from (select t.* from " + nameTable + " t order by 1 desc) where rownum = 1";

    @Query(value =lastEntryQueryFor, nativeQuery = true)
    Optional<Company> getLastEntry();
}

我有一个测试班。

@RunWith(SpringRunner.class)
@SpringBootTest
@Sql({
        "classpath:sql/create_sequence_different_types.sql",
        "classpath:sql/create-company.sql",
        "classpath:sql/insert_company.sql"
})
public class CompanyReadServiceTest {


    private static final Logger LOGGER = LoggerFactory.getLogger(CompanyReadServiceTest.class);

    private static String NAME_METHOD_READ_BY_NAME_BOOLEAN = "isByName";


    @Autowired
    private CompanyReadService companyReadService;

    @Autowired
    private CompanyReadRepositoryTest companyReadRepositoryTest;


    @Test
    public void getById() {
...

在类启动期间，bean CompanyReadRepositoryTest将不会加入。

java.lang.IllegalStateException：无法加载ApplicationContext

at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:132)
at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:123)
at org.springframework.test.context.web.ServletTestExecutionListener.setUpRequestContextIfNecessary(ServletTestExecutionListener.java:190)

...

原因：org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为'companyReadServiceTest'的bean时出错：通过字段'companyReadService'表示的不满足的依赖关系；嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为'com.service.read.company.CompanyReadService'的合格Bean：至少应有1个可以作为自动装配候选的Bean。依赖性注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）}在org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor $ AutowiredFieldElement.inject

任何想法是什么错误？请。

在您的情况下，CompanyReadRepositoryTest不会使用任何bean定义注释（例如@Component和对其进行扩展的注释）进行注释。 Spring无法识别所需类型的任何bean，因此无法将其注入到您的属性中。

如您所见，存在“ NoSuchBeanDefinitionException”，表示没有单个bean符合自动装配候选条件。

只需使用@Component（或任何bean定义注释）注释CompanyReadRepositoryTest，就可以了。

在您的情况下，最好的注释是@Repository。

看看@Repository和其他bean定义注释之间有什么区别。
