ヒストリックフォールバックメソッドでエラーが発生する

Question

Netflix Hystrixフォールバックメソッド&を簡単なスプリングプログラムで使用しようとしています。任意の構成が欠落している場合

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 

誰もが知っている、いくつかのチュートリアルで説明したように私はすべての基本的な手順に従ったが、まだ私はエラーを取得していますか？以下はコードスニペットです。

私のメイン、

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

私のコントローラ、

@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; 
    } 
} 

私は私のメインクラスを実行すると、私はこのエラーを取得し、

私の依存関係、

ています

Answer 1

私は何とかこの問題を解決しました。 MavenでAOP Jarsを使用しましたが、うまくいきました！

<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

このエラーは、依存関係の競合が原因で発生する可能性があります。

が

あなたはより良い依存関係の競合を避けるために、スプリング・クラウド・スターター・親を使用したい：あなたがしているように、私はので、いくつかの記事でHystrixにあなたの答えを見

<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>
