Spring Boot＆amp; Swagger 2：UnsatisfiedDependencyException - 存储库测试不起作用

时间：2017-12-02 21:43:09

标签： spring-mvc spring-boot swagger spring-test swagger-2.0

我有一个我一直在使用的Spring Boot Rest API，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：

$(document).ready(function(){
  
  // listen for change to #submitted element
  $('#answer').change(function(){
// things to do on change

if ( $('#answer').val() === '7' ){
  // things to do if the #answer text is 7
  $('#submitted').removeClass('disabled');
} else {
  // things to do if the #answer text is not 7
 $('#submitted').addClass('disabled');
};
  });
});

我不知道为什么会发生这种错误，因为这些测试与Swagger无关。

配置代码如下：

POM文件是这样的，使用Swagger 2.3.1：

@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", "", "", "", "", "");
    }
}

测试非常简单：

<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>
你能帮帮我吗？其余的测试工作正常。 谢谢！

问题是您的中央配置类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相关的基础架构。但是...... @EnableSwagger2创建的一些bean期望MVC基础架构到位，@DataJpaTest不是这样。

因此，为了从Spring Boot的测试切片支持（即@DataJpaTest）中受益，您需要将Swagger和MVC配置移动到一个单独的@Configuration类。

我也在这里回答了 [https://stackoverflow.com/a/52670119/8553816][1]

1。。使用WebMvcConfigurerAdapter适配器扩展swagger，并覆盖如下所述的addResourceHandlers方法和swagger配置方法：

UPDATE data SET value = 0.9234 WHERE fId = 47616 AND modDate = '2018-09-24'  AND valueDate = '2007-09-01'  AND last_updated < '2018-10-01';

注意： WebMvcConfigurerAdapter 在春季5中已弃用，因此请在春季5及更高版本中使用 WebMvcConfigurationSupport 。

2。。确保测试类也用@ SpringBootTest，@ RunWith（SpringRunner.class）以及@datajpatest进行了注释。

提示： ：创建一个自定义批注，并添加其他批注，例如@transactional等，并在回购测试类上使用此自定义批注。

3。最好使用不同的spring配置文件来运行测试用例，并且不要忘记使用@ActiveProfiles（“ profileHere”）注释测试类。

希望解决方案有效！

此外，请确保将您的 swagger 配置排除在 @SpringBootApplication 类之外，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 {

    // ...
}
