2、springcloud基本构建(Eureka)-服务提供者

项目工程目录如下

启动类EurekaClientApplication（增加了注解@EnableDiscoveryClient）注意跟注册中心服务注解不一样。。。。

package com.cloud.client;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaClientApplication {

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


}

application.properties

server.port=8092

spring.application.name=client-service
eureka.instance.hostname=localhost
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:8090/eureka

Demo类

package com.cloud.client.business;

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;


@RestController
@RequestMapping("/client/hello")
public class DemoController {

    @PostMapping("/world")
    public String helloWorld(@RequestParam("str") String str) {
        System.out.println("hello world");
        return str + " clientService";

    }


}

访问注册中心：http://localhost:8090/  该服务已在注册中心eureka注册成功
