Question

我正在尝试使用Netflix Hystrix Fallbackmethod＆amp;有一个简单的春季计划。我遵循了一些教程中描述的所有基本步骤，但我仍然收到错误，

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

任何人都知道是否缺少任何配置？以下是代码段。

我的主要，

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

我的控制器，

@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;
    }
}

当我运行我的Main类时，我收到此错误，

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

我的依赖，

Answer 1

我已经以某种方式解决了这个问题。我在Maven中使用了AOP Jars，它工作得很好!!

 <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

此错误可能是由maven依赖冲突引起的。

您最好使用spring-cloud-starter-parent来避免依赖冲突：

    <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>

Hystrix后备方法给出了错误
