Distributed, microservices, cloud architectureJava language development, cross-platform, high-performance, high-availability, secure, service-based, modular, component-driven development modelFrom 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 scholars. Let's explore how

Application {public static void main(String[] args) {new SpringApplicationBuilder(ComputeServiceApplication.class).web(true).run(args);}}After we have completed the implementation of the service content, we will continue to do some configuration work for Application.properties, as follows:spring.application.name=eureka-clientserver.port=2001eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/With the Spring.application.name property, we can specify that the name of the

restore the original master logic? For this problem, Hystrix also realized the automatic recovery function for us. When the circuit breaker opens, the main logic of the fuse, Hystrix will start a sleep time window, in this time window, the demotion logic is temporary into the primary logic, when the sleep time window expires, the circuit breaker will enter the semi-open state, release a request to the original master logic, if the request returned normally, Then the circuit breaker will continu

Microservices-webapi implementation, separation from iis, and tomcat-webapitomcatPreface Microservice, as its name implies, is a tiny, single service program, a single process, a single release, development and deployment can be independent; This is my understanding; However, web-based services, such as webservice and webapi, must be based on iis or tomcat, This article describes how to deploy plain text programs based on http services by bypassing ii
