This article mainly explains the "basic deployment tutorial of eureka+zuul in Micro Services". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and study the "basic deployment tutorial of eureka+zuul in Micro Services".

Some time ago, when I encountered a work crisis, I almost realized the importance of technology, so I began to understand and learn about micro-services on the advice of the company architect. The first thing I learned was the zuul gateway and the eureka registry. Because there was a lot of work and development during the day, I had to study at night. Now I can simply deploy a set of environment and run it successfully. Although these can be regarded as scratching the surface for the veteran, it is still a pleasure for me.

On the relevant introduction of zuul and eureka, I will not say more about a large number of search, directly on the configuration.

1. First create the Spring boot.

Next, change the project name.

And then continue to the next step, I directly skip the selection of components in the middle, or add it in pom after creation.

two。 Introduce dependency

Eureka:

Org.springframework.cloud spring-cloud-starter-netflix-eureka-client

Dome1 、 dome2:

Org.springframework.cloud spring-cloud-starter-netflix-eureka-client org.springframework.boot spring-boot-starter-web

3. Startup class annotation

Eureka:

@ EnableEurekaServer

Zuul:

@ EnableZuulProxy

Dome1 、 dome2:

@ EnableEurekaClient

4: configuration fil

Eureka:application.properties

Whether server.port=8080eureka.instance.hostname=127.0.0.1# registers its own eureka.client.register-with-eureka=false# with the service center, retrieves the configuration content of the service eureka.client.fetch-registry=falseeureka.instance.prefer-ip-address=true# service registry, and specifies the location of the service registry eureka.client.service-url.defaultZone= http://${eureka.instance.hostname}:${server.port}/eureka/

Zuul:application.yml

Server: port: 8084 # Service port spring: application: name: api-zuul # Service name eureka: client: registry-fetch-interval-seconds: 5 # cycle of getting service list: 5s service-url: defaultZone: http://127.0.0.1:8080/eureka # eureka address zuul: prefix: / api # add routing prefix all access routes plus this prefix retryable: true # whether it is on Enable retry function routes: api: # casually use path: / service/** # access address with service request will be forwarded to service-provider-A serviceId: service-provider-A # if both service names are registered with service-provider-A to eureka Zuul will forward it randomly.

Dome1, dome2:application.properties (different ports, same service name)

# Registration address of the registry eureka.client.service-url.defaultZone= http://127.0.0.1:8080/eureka/# service name-- the method spring.application.name=service-provider-Aserver.port=8081 that invokes the service based on its name when called

The above configuration is cloud load balancer configuration. Reverse proxy can add a name to the configuration under routes in zuul, and path and serviceid can be another service name.

Dome1 and dome2 each need to create a test class.

Package com.example.eurekaclientdemo.controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map;@RequestMapping ("/ users") @ RestControllerpublic class UserController {@ GetMapping ("/ {name}") public Map getUser (@ PathVariable ("name") String userName) {Map data = new HashMap () Data.put ("id", userName); data.put ("from", "provider-A-1"); return data;}} package com.example.eurekaclient2demo.controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map @ RequestMapping ("/ users") @ RestControllerpublic class UserController {@ GetMapping ("/ {name}") public Map getUser (@ PathVariable ("name") String userName) {Map data = new HashMap (); data.put ("id", userName); data.put ("from", "provider-A-2"); return data;}}

After the above configuration is completed, start eureka, zuul, dome1, and dome2 in turn. View registered services after entering http://127.0.0.1:8080 in the browser

Then type http://127.0.0.1:8084/api/service/users/sdffsd in the browser and need to refresh to see the effect.

Thank you for your reading. the above is the content of the basic deployment tutorial of eureka+zuul in Micro Services.
