SpringCloud系列使用Eureka进行服务治理 (3)

eureka也引用SpringBoot actuator监控管理，SpringBoot actuator可以参考我之前博客： SpringBoot系列之actuator监控管理极速入门与实践

具体可以进行配置，配置成eureka server的ip，加上actuator

eureka: instance: status-page-url-path: :8761/actuator/info health-check-url-path: :8761/actuator/health

显示ip和实例id配置：

6. Eureka服务消费者 server: port: 8082 spring: application: name: eureka-service-consumer eureka: client: service-url: defaultZone: :8761/eureka/ fetch-registry: true register-with-eureka: false healthcheck: enabled: false instance: status-page-url-path: :8761/actuator/info health-check-url-path: :8761/actuator//health prefer-ip-address: true instance-id: eureka-service-consumer8082

关键点，使用SpringCloud的@LoadBalanced，才能调? 接口的数据，浏览器是不能直接调的

package com.example.springcloud.consumer; import com.example.springcloud.consumer.bean.User; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.loadbalancer.LoadBalanced; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.context.annotation.Bean; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.client.RestTemplate; @SpringBootApplication @EnableEurekaClient @RestController public class SpringcloudServiceConsumerApplication { @Bean @LoadBalanced public RestTemplate restTemplate(){ return new RestTemplate(); } public static void main(String[] args) { SpringApplication.run(SpringcloudServiceConsumerApplication.class, args); } @GetMapping("/findUser/{username}") public User index(@PathVariable("username")String username){ return restTemplate().getForObject("http://EUREKA-SERVICE-PROVIDER/api/users/"+username,User.class); } }
