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

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.7.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>

 

<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Brixton.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

 

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>
