La méthode de repli Hystrix donne une erreur

Question

J'essaie d'utiliser la méthode de repli Netflix Hystrix & avec un programme de ressort simple. J'ai suivi toutes les étapes de base comme décrit en cours d'instruction, mais je reçois l'erreur,

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hystrixCommandAspect' defined in class path resource [org/springframework/cloud/netflix/hystrix/HystrixCircuitBreakerConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to inst 

Quelqu'un sait si une configuration est manquante? Voici l'extrait de code ci-dessous.

Mon principal,

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

Mon contrôleur,

@RestController 
@Component 
public class TestController { 

    @RequestMapping(value = "/hello", method = RequestMethod.GET) 
    @HystrixCommand(fallbackMethod="Error") 
    public String Hello() { 
     String text = "Hi Hello, you have come to correct place"; 

     //creating an exception to trigger fallBackMethod!!! 
     if(text != "something") 
      throw new RuntimeException(); 

     return text; 
    } 

    public String Error() { 
     String text = "Error - this is an backup text"; 

     return text; 
    } 
} 

Quand je lance ma classe principale, je reçois cette erreur,

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hystrixCommandAspect' defined in class path resource [org/springframework/cloud/netflix/hystrix/HystrixCircuitBreakerConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.hystrix.contrib.javanica.aop.aspectj.HystrixCommandAspect]: Factory method 'hystrixCommandAspect' threw exception; nested exception is java.lang.NoClassDefFoundError: org/aspectj/lang/JoinPoint

Mes dépendances,

Answer 1

J'ai en quelque sorte résolu ce problème. J'ai utilisé des pots AOP à Maven, et ça marche bien !!

<dependency> 
      <groupId>org.aspectj</groupId> 
      <artifactId>aspectjrt</artifactId> 
      <version>1.7.1</version> 
     </dependency> 
     <dependency> 
      <groupId>org.aspectj</groupId> 
      <artifactId>aspectjweaver</artifactId> 
      <version>1.7.1</version> 
     </dependency> 
     <dependency> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-aspects</artifactId> 
     </dependency> 

Answer 2

Cette erreur peut résulter d'un conflit de dépendance maven.

Vous feriez mieux d'utiliser-parent nuage-démarreur printemps pour éviter les conflits de dépendance:

<parent> 
     <groupId>org.springframework.cloud</groupId> 
     <artifactId>spring-cloud-starter-parent</artifactId> 
     <version>Camden.SR7</version> <-- release version --> 
     <relativePath/> <!-- lookup parent from repository --> 
    </parent> 

    ... 

    <dependency> 
     <groupId>org.springframework.cloud</groupId> 
     <artifactId>spring-cloud-starter-hystrix</artifactId> 
     <!--<version>1.3.6.RELEASE</version>--> <-- no need --> 
    </dependency>
