Hystrix fallback method gives error - spring-cloud

Question

I am trying to use Netflix Hystrix Fallbackmethod & with a simple spring program. i followed all the basic steps as described in some tutorials, but still I am getting error,
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
Anyone know if any configuration is missing? Below is the code snippet.
My Main,
#SpringBootApplication
#EnableCircuitBreaker
public class SpringBootHelloWorldApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootHelloWorldApplication.class, args);
}
}
My Controller,
#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;
}
}
When i run my Main class, I am getting this error,
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

My Dependencies,

Answer 1

I have somehow solved this issue.
I used AOP Jars in Maven, and it is working fine!!
<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

This error may result from maven dependency conflict.
You'd better use spring-cloud-starter-parent to avoid dependency conflict:
<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>
