The Problem:
When running a discovery server with specific dependencies(spring cloud and spring boot), an error occurs: java.lang.IllegalStateException: Error processing condition on org.springframework.cloud.loadbalancer.config.LoadBalancerAutoConfiguration.loadBalancerClientFact
The Solutions:
Solution 1: Use Spring Cloud version 2021.0.x
Explanation:
The error message indicates that it fails to introspect a method or class from the org.springframework.cloud.loadbalancer.config.LoadBalancerAutoConfiguration class due to a missing dependency or class definition.
The specific missing class mentioned is org.springframework.beans.factory.aot.BeanRegistrationAotProcessor, which is part of Spring’s Ahead-of-Time (AOT) compilation capabilities, which are only supported in recent versions of Spring Framework and Spring Boot.
By using Spring Cloud version 2021.0.x, which is compatible with Spring Boot 2.7.x-SNAPSHOT, you can avoid this error as it does not rely on the AOT compilation features.
