Question

我创建了一个springboot（2）webflux项目，如下所示：

JPA实体

@Entity
@Table(name = "users")
public class User implements Serializable
{
...
}

Spring存储库

public interface UserRepository extends CrudRepository<User, Long>
{
}

服务

@Service
public class UserService
{
    @Autowired
    private UserRepository userRepo;
    ...
}

Webflux Handler

@Component
public class UserHandler
{
    @Autowired
    private UserService userService;

    public Mono<ServerResponse> getUser(ServerRequest request)
    {
    ...
    }
}

RouteConfiguration

@Configuration
public class RouteConfiguration
{
    @Bean
    public static RouterFunction<ServerResponse> userRoutes(UserHandler userHandler)
    {
        return RouterFunctions.route(RequestPredicates.GET("/user"), userHandler:: getUser);
    }

Web应用程序

@SpringBootApplication
public class WebApplication
{
    public static void main(String[] args)
    {
        SpringApplication.run(WebApplication.class);
    }
}

POM

</dependencies>

一切正常，我可以启动我的服务器并使用它。我现在想编写一些测试代码。这是我做的：

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = WebApplication.class)
public class UserHandlerTest
{
    @Autowired
    private ApplicationContext context;
    @MockBean
    private UserService userService;
    private WebTestClient testClient;

    @Before
    public void setUp()
    {
        testClient = WebTestClient.bindToApplicationContext(context).build();
    }

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

我尝试了什么，在＆＃34; mvn clean install＆＃34;中出现了hibernate依赖关系的错误。过程：

[ERROR] testUser（... UserHandlerTest）经过的时间：0秒＆lt;＆lt;＆lt;错误！ java.lang.IllegalStateException：无法加载ApplicationContext 引起：org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; entityManagerFactory＆＃39;的bean时出错在类路径资源中定义[org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaConfiguration.class]：调用init方法失败;嵌套异常是java.lang.NoClassDefFoundError：无法初始化类org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl 引起：java.lang.NoClassDefFoundError：无法初始化类org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl

我知道JPA以阻塞的方式工作，但我想避免在这个项目中使用NoSQL DB。我错过了什么？非常感谢你的帮助！

可能您缺少我们需要在src / main / resources下为数据源提供的详细信息。你可以查看https://github.com/hantsy/spring-reactive-sample/blob/master/boot-data-mongo/src/main/resources/application.yml。这可能对你有帮助。

为了测试我的Spring Webflux控制器，我最终使用了WebFluxTest注释。它按预期工作：

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {RouteConfiguration.class, UserHandler.class})
@WebFluxTest
public class UserHandlerTest
{
    @Autowired
    private ApplicationContext context;
    @MockBean(name="userService")
    private UserService userService;
    private WebTestClient testClient;

    @Before
    public void setUp()
    {
        testClient = WebTestClient.bindToApplicationContext(context).build();
    }

    ...

由于我不使用RestController注释，而是使用功能端点，我必须使用ContextConfiguration并手动实例化WebTestClient。
