# Ribbon timeout setting # ribbon: # ConnectTimeout: 500 # ReadTimeout: 3000 Hystrix is a configuration pitfall for a long time. The Spring Cloud I use is Dalston SR1, Which is newer than other materials on the Internet, because Feign's support for Hystrix is disabled by default in the new version, therefore, manually enable feign through configuration. hystrix. enabled = true, so that service downgrade and other functions will be effective.

certain load balancing policy through Ribbon. (4) If the Feign, service client, and services need to access each other, you can use RestTemplate or Feign client. By default, it uses Ribbon for load balancing. (5) Hystrix, monitoring and circuit breaker. We only need to add the Hystrix tag to the service interface to implement monitoring and circuit breaker functions for this interface. (6) Hystrix Dashboard, monitoring panel, which provides an interface to monitor the time consumed by service c

I. OverviewOne of the most popular features in Springboot is the automatic configuration. Springboot helps us to configure the entire development environment based on automatic configuration, which allows us to not have to do the repetitive configuration work every time.In this, we will analyze the principle of automatic configuration.Two. program start-Up class@SpringBootApplication Public class Springbootrunnerclass { publicstaticvoid main

ObjectiveIn the first few chapters we have seen the springboot for us to do automatic configuration, indeed convenient and fast, but for beginners, if not understand springboot internal starting principle, will inevitably suffer.
