Ошибка создания bean с именем 'bindingService' - Eureka & Bus AMQP

Question

Я пытаюсь интегрировать Hystrix в мое текущее весеннее облако & Проект микросервиса Netflix OSS.

У меня есть свежий Spring загрузочной версии 1.4.0.RELEASE проект с двумя зависимостями:

<dependency> 
     <groupId>org.springframework.cloud</groupId> 
     <artifactId>spring-cloud-starter-eureka</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.cloud</groupId> 
     <artifactId>spring-cloud-starter-bus-amqp</artifactId> 
    </dependency> 

При запуске проекта я получаю это исключение:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bindingService' defined in class path resource [org/springframework/cloud/stream/config/ChannelBindingServiceConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.stream.binding.ChannelBindingService]: Factory method 'bindingService' threw exception; nested exception is java.lang.NoClassDefFoundError: javax/validation/Validator 

Это исключение происходит только тогда, когда и Eureka & Зависимости между шинами AMQP.

Конфигурация не установлена ​​в приложении или bootstrap .yml/.properties.

Единственный класс настоящее Java является один порождена Spring Boot:

@SpringBootApplication 
public class DummyProjectApplication { 

    public static void main(String[] args) { 
     SpringApplication.run(DummyProjectApplication.class, args); 
    } 
}

Answer 1

Я думаю java.lang.NoClassDefFoundError: javax/validation/Validator должен быть ключ. Этот класс не включен в две (довольно странные) зависимости. Мы могли бы сидеть и обсуждать, следует ли включать его, или вы можете просто включить его самостоятельно (например, через spring-boot-starter-web, который является обычным источником, или spring-boot-starter-validation, если вам не нужны веб-материалы).
