Problem Description:

tip: version dependency is the worst problem

Solution:

Introduce spring cloud loadbalancer dependency

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-loadbalancer</artifactId>
    <version>3.0.3</version>
</dependency>

Due to the version problem, some must exclude ribbon dependencies from Nacos, otherwise the loadbalancer is invalid

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    <!--Client-side load balancing without Ribbon-->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
        </exclusion>
    </exclusions>
</dependency>
