Use Spring-Cloud to build a microservice architecture

To build a microservice architecture, I personally feel that the following modules must be used:

• config-service
• api-gateway
• circuit-breaker
• registry
• monitor
• ***-service

The first step is to build config-service, log in to http://start.spring.io/, select gradle, maven, basic information, and more importantly, select the required dependencies

	<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-server</artifactId>
		</dependency>

 

If you need to customize the port and repo address, here I declare that the port is 8877, and the repo is local. Assuming that you follow the CI, you can read the url address. There is no need for native here, but the git.uri address is required.

spring:
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/profiles

server:
  port: 8877

 

After the build is complete, the first config-service is completed

 

 

Build registry-service, a very important point EnableEurekaServer

 

spring:
  application:
    name: registry
  cloud:
    config:
      uri: http://localhost:8877
      fail-fast: true
      password: 123456
      username: user

eureka:
  instance:
    prefer-ip-address: true
  client:
    registerWithEureka: false
    fetchRegistry: false
    server:
      waitTimeInMsWhenSyncEmpty: 0

 How to solve the fuse? It can be done by fallbackmethod

@Override
    @HystrixCommand(groupKey = "say", fallbackMethod = "fallBackCall")
    public String ping() {
        return service2.ping();
    }
