To Setup Eureka Server And Register A Microservice
Posted By : Manish Kumar Narang | 28-Feb-2018
In this blog, we shall see how to make a spring boot application act as eureka server and register a spring boot application in it as eureka client which will in turn act as a microservice.
Now first we will setup a Eureka Server.
package com.example.eurekasetup;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
@EnableZuulProxy
@EnableEurekaServer
@SpringBootApplication
public class EurekaServiceApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServiceApplication.class, args);
}
}
In the application.yml we will configure the port number and put other details. Observe that the eureka.client parameters have been disabled since this spring boot application will act as a Eureka server.
spring:
application:
name: eureka-server
server:
port: 8302
eureka:
client:
registerWithEureka: false
fetchRegistry: false
server:
waitTimeInMsWhenSyncEmpty: 0
zuul:
#Service will be mapped under the /api URI
prefix: /api
routes:
service1:
path: /service1/**
url: http://localhost:8300
Now we will create a spring boot application which we will act as a Eureka client and we will register it with the Eureka server.
package com.example.service1;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@EnableEurekaClient
@SpringBootApplication
public class DbServiceApplication {
public static void main(String[] args) {
SpringApplication.run(DbServiceApplication.class, args);
}
}
In the application.properties,
spring.application.name=service1
server.port=8300
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password =root
spring.datasource.tomcat.testWhileIdle=true
spring.datasource.tomcat.validationQuery=SELECT 1
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming.implicit-strategy=-strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
In the application.yml, configure this as a eureka client by enabling the eureka.client parameters and by mentioning the url of eureka server as below.
eureka:
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://localhost:8302/eureka/
instance:
hostname: localhost
