环境：spring boot： 1.3.7 spring cloud ： Brixton.SR5

添加
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
添加注解 @SpringCloudApplication
添加 @HystrixCommand(fallbackMethod = "helloFallBack")
后，启动tomcat时报以下错误：
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
看来是jar包有问题了
最后试了n个依赖，最后只添加了下面这个依赖就好了
<dependency>
<groupId> org.aspectj</groupId>
<artifactId> aspectjweaver</artifactId>
<version> 1.6.11</version>
</dependency>
