springcloud使用hystrix断路器错误

原因： spring2.x.x>=2.0.0已经去掉了org/springframework/boot/autoconfigure/web/ServerPropertiesAutoConfiguration.class，如果导入的Jar包需要依赖这个就会报错

解决办法：

 		<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-ribbon</artifactId>
            <version>1.4.2.RELEASE</version>
        </dependency>
        <!--断路器-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix</artifactId>
            <version>1.4.4.RELEASE</version>
        </dependency>

替换成

		<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>
        <!--断路器-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
            <version>2.1.0.RELEASE</version>
        </dependency>
