, the service will not get the latest configuration information and need to solve this problem to introduce refresh. You can reload the configuration file during the run of the service.When all the configuration files are stored in the configuration center, the configuration center becomes a very important component. If a problem with the configuration center can result in catastrophic consequences, it is recommended that you cluster the configuration center in production to support high availab

implementation of the eureka-client Eureka through the interfaces defined by spring cloud DiscoveryClient . Since spring cloud has done a very good job of abstraction in the service discovery layer, for the above program, we can seamlessly switch from Eureka's service governance system to Consul's service governance s

of the Eureka-client service, and can also observe its load balancing effect by initiating multiple eureka-client services.From now on, I will record the process and the essence of the recently developed Springcloud micro-service cloud architecture, and help more friends who are interested in developing the Spring cloud framework, hoping to help more good schola

return true, so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter.Run: The specific logic of the filter. Here we use Ctx.setsendzuulresponse (false) to make Zuul filter the request, do not route it, and then set its return error code via CTX.SETRESPONSESTATUSCODE (401). Of course, we can also further optimize our return, for example, by Ctx.setresponsebody (body) to return the body content to edit and so on.After impl
