I was facing the similar issue, mine was due to maven dependency import. Try starting the application by adding the following dependencies:


<dependency>
    <groupId>org.springframework.cloud</groupId>        
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
    <version>2.2.2.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-circuitbreaker-reactor-resilience4j</artifactId>
</dependency>

and also remove the existing dependency:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix</artifactId>
    <version>1.4.7.RELEASE</version>
</dependency>
