Spring测试需要控制器不使用的几个bean

我有一个关于Spring（v2.2.2.RELEASE）控制器的测试，它失败了，因为它需要一些控制器不需要的bean。为什么需要这些豆子

控制器

@Api(description = "Exercises")
@CrossOrigin(origins = ["*"])
@RestController
@RequestMapping("/api/exercises")
class ExerciseController(
        val repo: ExerciseRepository,
        val userAuditing: UserAuditing
) : ResourceRestController<Exercise, String>(repo)  {
    @PostMapping("")
    override fun create(@RequestBody resource: Exercise): Mono<ResponseEntity<Exercise>> {
        // TODO Free Coaches members just can create public exercises!
        return super.create(resource)
    }
}

abstract class ResourceRestController<T : Resource, ID>(private val repository: ReactiveMongoRepository<T, ID>) {
   @PostMapping
   open fun create(@RequestBody resource: T) = repository.save(resource)
            .map { o -> ResponseEntity(o, HttpStatus.CREATED) }
            .onErrorMap { err ->
                log.error("Error occurred while creating the resource", err);
                HttpServerErrorException(HttpStatus.INTERNAL_SERVER_ERROR, "Error occurred while creating the resource")
   }
}

结果

如果没有在ExerciseController中使用mocking Training Repository，为什么我需要它？

例如@JBNizet注释，我创建了两个配置类并移动了注释

此类将替换后端应用程序中的@EnableWebFlux：

@配置
类WebfluxConfig:WebFluxConfiger{
重写fun addResourceHandlers（注册表：ResourceHandlerRegistry）{
registry.addResourceHandler（“/swagger ui.html**”）
.addResourceLocations（“类路径：/META-INF/resources/”）
registry.addResourceHandler（“/webjars/**”）
.addResourceLocations（“类路径：/META-INF/resources/webjars/”）
}
}

此类将替换后端应用程序中的@EnableReactiveMongorPositories:

@配置
@EnableReactiveMongorPositories
MongoConfig类{
}

因此，主要类别：

@springboot应用程序
类后端应用程序
趣味主线（args:Array）{
运行应用程序（*args）
}

培训库

不是问题所在，无法找到

reactiveMongoTemplate

。您有一个

SpringRunner

注释，用于加载ApplicationContext，无论您在测试中是否使用它，它都是训练库及其所需的所有依赖项的一部分。@Matt否：这是一个WebFluxTest，因此它只应添加控制器层所需的控制器和bean（对象映射器等）。该测试应该提供模拟依赖项。这是一个切片测试。@Fran您确定UserAuditing对TrainingRepository没有依赖项吗？找到注入TrainingRepository的所有bean。@jbnize，哦，我明白了。我的错。您的后端应用程序同时具有EnableWebFlux和EnableReactiveMongorPositories。创建两个separate配置类，每个类只有一个注释（即，每个片段一个注释）。实际上，只创建一个注释，因为Spring引导应用程序不应该使用EnableWebFlux，除非您不希望引导自动配置webflux，而是希望自己配置所有注释。
