springCloud当中Eureca服务提供者Provider的部署
服务提供者的部署
马克-to-win@马克java社区:做个普通的maven project,quickstart archetype。改成jdk.8。运行程序后会出现:EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.这个提示跟保护模式相关,和我们的Helloworld例子无关,这里就略过了。马克-to-win@马克java社区:当然,可以在前面的server配置文件处,把它关了,enable-self-preservation:false。马克-to-win@马克java社区:另外,Eureka本身是一个基于REST的服务,所以你会发现大家通常的服务或消费微服务,都做成是基于REST的服务。马克- to-win:马克 java社区:防盗版实名手机尾号: 73203。

/*EnableEurekaClient的意思是让你的应用成为eureca的客户,你在用它,你是他的客户,你没在用别人,没有它,不报错,但是8761服务器发现不了这个client。整个euraka的helloworld三个项目,包括服务器,provider,consumer不能正确配合工作。*/
@SpringBootApplication
@EnableEurekaClient
@RestController
public class Application {
@RequestMapping("/")
public String home() {
return "Hello world 马克-to-win";
}
@RequestMapping("/acquire")
public String acquire() {
return "Hello 马克-to-win acquire";
}
public static void main(String[] args) {
SpringApplication.run(Application.class,args);
}
}
运行结果:
以上是我们独立用浏览器测试服务提供者。没什么问题,以下我们可以在程序中测试以上服务提供者。
