解决方案

• 如果使用的是Eureka需要引入ribbon依赖

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
            <version>2.2.9.RELEASE</version>
        </dependency>

• 如果使用的是Nacos，引入了spring-cloud-starter-alibaba-nacos-discovery，则不再需要引入ribbon，其包含了ribbon。

如果你在nacos项目中使用了LoadBalancer，需要引入如下依赖。如果没有则不需要。

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
        </dependency>
