Spring Boot & Swagger 2：UnsatisfiedDependencyException - 存储库测试不工作
Spring Boot & Swagger 2 : UnsatisfiedDependencyException - Repository tests not working
我有一个 Spring Boot Rest API 我一直在工作，上周我添加了 Swagger 和 Swagger-UI。之后，存储库的测试（仅与存储库相关的测试）开始不起作用，当我 运行 它们时，我收到此错误：

我不知道为什么会出现这个错误，因为这些测试与 Swagger 无关。
配置代码是这样的：
@EnableSwagger2
@SpringBootApplication
public class UserServiceApplication extends WebMvcConfigurerAdapter {
public static void main(String[] args) {
SpringApplication.run(UserServiceApplication.class, args);
}
@Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2)
.select().apis(RequestHandlerSelectors.basePackage(getClass().getPackage().getName()))
.paths(PathSelectors.any())
.build()
.apiInfo(generateApiInfo());
}
private ApiInfo generateApiInfo() {
return new ApiInfo("User Service", "User Service", "", "", "", "", "");
}
}
POM文件是这样的，用Swagger 2.3.1：
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>${io.springfox.springfox-swagger2}</version>
</dependency>
<!-- Include swagger for API description UI -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>${io.springfox.springfox-swagger-ui}</version>
</dependency>
而且测试很简单：
@RunWith(SpringRunner.class)
@DataJpaTest
@Transactional
public class UserRepositoryTest {
@Autowired
private TestEntityManager entityManager;
@Autowired
private UserRepository userRepository;
@Test
public void whenPersistingAnUserTheUserAndImageAreSaved(){
UserImage userImage = new UserImage("key","URL");
User user = new User("email@mail.com", "pass","name","lastNmae","description","123123",userImage);
User savedUser = userRepository.save(user);
assertNotNull(savedUser.getId());
assertNotNull(savedUser.getUserImage().getId());
}
你能帮帮我吗？其余测试工作正常。
谢谢！
问题是您的中央配置 class UserServiceApplication 正在设置 Swagger 和 Spring MVC。当您使用 @DataJpaTest 时，您实际上是在告诉 Spring Boot 而不是 加载 Spring MVC 相关基础结构。但是...... @EnableSwagger2 创建的一些 bean 期望 MVC 基础设施到位，而 @DataJpaTest 并非如此。
因此，为了受益于 Spring Boot 的 测试切片 支持（即 @DataJpaTest），您需要移动 Swagger 和MVC 配置到一个单独的 @Configuration class.
我也在这里回答过：
.
1. 使用 WebMvcConfigurerAdapter 适配器扩展 swagger 并重写如下所述的 addResourceHandlers 方法以及 swagger 配置方法：
@Override
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
注意： WebMvcConfigurerAdapter 在 spring 5 中已弃用，因此请使用 WebMvcConfigurationSupport 在 spring 5 及更高版本中。
2. 确保您的测试 class 也使用 @SpringBootTest、@RunWith(SpringRunner.class) 和 @datajpatest 进行注释。
提示： 创建自定义注释并添加一堆其他注释 loke @transactional 等，并在回购测试中使用此自定义注释classes.
3. 最好对 运行 测试用例使用不同的 spring 配置文件，并且不要忘记用 class 注释测试@ActiveProfiles("profileHere").
希望解决方案有效！
此外，请确保您的 swagger 配置不在 @SpringBootApplication class 中，包括 @EnableSwagger2 注释：
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
@Configuration
@EnableSwagger2
public class SwaggerConfig extends WebMvcConfigurationSupport {
