3.Springcloud 搭建服务提供者注册到eureka

1.添加依赖

2.配置文件

#端口号
[email protected]@
# 配置的应用名称
spring.application.name=tour-account-service
#注册到eureka
eureka.client.service-url.defaultZone=http://@eureka.host@:@server.eureka.port@/eureka

#端口号
server:
  port: @server.account.port@
# 配置的应用名称
spring:
  application:
    name: tour-account-service
#注册到eureka
eureka:
  client:
    service-url:
      defaultZone: http://@eureka.host@:@server.eureka.port@/eureka

3.服务

@RestController
public class AccountApiController {
   
    @RequestMapping("/hello")
    public String testHello(String name){
        return "你好！ "+name+" 我是带一个String类型的参数的方法！";
    }
}

4.启动项目

@SpringBootApplication
@EnableEurekaClient
public class AccountServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(AccountServiceApplication.class,args);
    }
}
