基于Eureka的服务注册和发现 provider-eureka

目录

application.yml

server:
  port: 7070

spring:
  application:
    name: provider-eureka

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8888/eureka/

ProviderEurekaApplication

@SpringBootApplication
@EnableEurekaClient
public class ProviderEurekaApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProviderEurekaApplication.class, args);
    }

}

EchoServiceController

@RestController
@RequestMapping("/pe")
public class EchoServiceController {
    @Autowired
    private EchoService echoService;

    @GetMapping("/echo")
    public String echo(@RequestParam String name) {
        return echoService.echo(name);
    }
}

基于Nacos的服务注册和发现 provider-nacos

目录
