我也面临着类似的问题，我的问题是由于maven依赖项导入造成的。尝试通过添加以下依赖项来启动应用程序：

<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>

并删除现有的依赖关系：

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