node microservices architecture

About Spring CloudSpring Cloud is a spring boot-based cloud application development tool for configuration management, service discovery, circuit breakers, intelligent routing, micro-agents, control buses, global locks, decision-making campaigns, Operations such as distributed sessions and cluster state management provide a simple way to develop.Spring Cloud contains multiple sub-projects (for many different open source products involved in distributed systems), such as spring Cloud Config, Spri

Spring Cloud combines today's more mature, proven service framework with the spring boot style for re-encapsulation, masking complex configuration and implementation principles, and ultimately integrating a simple, easy-to-deploy and maintainable Distributed system architecture platform.Spring Cloud's sub-projects can be broadly divided into two categories: the package and abstraction of Spring boot for existing mature frameworks, and the largest numb

instance Pom.xml to turn on the monitoring-related endpoint and ensure that the dependency Spring-cloud-starter-hystrix for the circuit breaker has been introduced:Ensure that the @enablecircuitbreaker or @enablehystrix annotations have been used in the main class of the service instance to turn on the circuit breaker function.All the configurations have been completed, the "Eureka-consumer-ribbon-hystrix" monitoring has been initiated and the "Monitor Stream" button has been clicked.From now o

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

Let's explore how the Spring cloud architecture
