Core Class

SpringApplication SpringApplicationBuilder BootstrapConfiguration

DiscoveryClient ServiceRegistry LoadBalancerClient

Notes

Cloud核心包： Spring Cloud Context and Spring Cloud Commons and Spring Cloud Load Balancer and Circuit breaker

child contexts inherit property sources and profiles from their parent

common patterns: service discovery, load balancing, and circuit breakers

springcloud common loadbalance and spring cloud loadbalance 区别是什么？

common里面提供的接口，并没有提供实现，而spring cloud loadbalance提供了实现。 service discovery/register 实现：consul,zk,eureka load balancing 实现：spring cloud loadbalance circuit breaker实现：Resilience4J，Sentinel，Spring Retry(Spring Cloud Circuit Breaker)

一些新的endpoint,引入了spring-boot-actuator，refresh，restart，pause，env

Refresh入口类是：RefreshEndpoint，RefreshScope实现了GenericScope，GenericScope实现了Scope类， 也就是@RefreshScope是@Scope("refresh")
