This article is about how to implement service registration consul in Spring Cloud. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
A brief introduction to consul
Consul has the following properties:
Service Discovery: consul registers services through http, and services and services interact with each other.
Service health monitoring
Key/value storage
Multiple data centers
Consul can run on machines such as mac windows linux.
II. Consul installation
Linux
$mkdir-p $GOPATH/src/github.com/hashicorp & & cd $! $git clone https://github.com/hashicorp/consul.git$ cd consul$ make bootstrap$ make bootstrap
Install under windows:
See how to install consul under windows
III. Construction project
Build a springboot project for consul-miya, and import the dependent pring-cloud-starter-consul-discovery, which depends on the file:
4.0.0 com.forezp consul-miya 0.0.1-SNAPSHOT jar consul-miya Demo project for Spring Boot org.springframework.boot spring-boot-starter-parent 1.5.2.RELEASE UTF-8 UTF-8 1.8 org.springframework.cloud spring-cloud-starter-consul -discovery org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.springframework.cloud spring-cloud-dependencies Dalston.RELEASE Pom import org.springframework.boot spring-boot-maven-plugin
Add the annotation @ EnableDiscoveryClient to its entry file ConsulMiyaApplication to enable service discovery:
@ SpringBootApplication@EnableDiscoveryClient@RestControllerpublic class ConsulMiyaApplication {@ RequestMapping ("/ hi") public String home () {return "hi, IBM miya";} public static void main (String [] args) {new SpringApplicationBuilder (ConsulMiyaApplication.class) .web (true) .run (args);}}
Specify the port of the consul service in its configuration file application.yml as 8500:
Spring: cloud: consul: host: localhost port: 8500 discovery: healthCheckPath: ${management.contextPath} / health healthCheckInterval: 15s instance-id: consul-miya application: name: consul-miyaserver: port: 8502
Start the project, visit localhost:8500, and you can find that consul-miya is registered.
