Eureka服务端:
EurekaApplication.java
package com.packtpub.Eureka; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer; @EnableEurekaServer @SpringBootApplication public class EurekaApplication { public static void main(String[] args) { // SpringApplication.run(EurekaApplication.class, args); new SpringApplicationBuilder(EurekaApplication.class).web(true).run(args); } }
application.properties
server.port=1111 eureka.client.register-with-eureka=false eureka.client.fetch-registry=false eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/
Eureka客户端:
package com.packtpub.EurekaClient; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; @EnableDiscoveryClient @SpringBootApplication public class EurekaClientApplication { public static void main(String[] args) { //SpringApplication.run(EurekaClientApplication.class, args); new SpringApplicationBuilder(EurekaClientApplication.class).web(true).run(args); } }
