前言

上一节我们搭建起了服务注册中心,为各个服务提供者和消费者提供一个桥梁,这一节我们搭建一个服务提供者,注册到注册中心

新建eureka-client模块

代码结构如下:

代码编写

cppba-spring-cloud-eureka-client > pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <packaging>jar</packaging>
  <name>${project.artifactId}</name>

  <parent>
    <groupId>com.cppba</groupId>
    <artifactId>cppba-spring-cloud</artifactId>
    <version>1.0.0</version>

  <dependencies>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>
  </dependencies>
</project>

SpringCloudEurekaClientApplication.java

package com.cppba;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@EnableEurekaClient
@RestController
public class SpringCloudEurekaClientApplication {

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

  @Value("${server.port}")
  private String port;

  @RequestMapping("/hi")
  public String sayHi(@RequestParam String name) {
    return "hi " + name + ",i am from port:" + port;
  }
}

application.properties

server.port=8764

eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/

spring.application.name=service-say

到此项目搭建完成

启动项目

启动eureka-client之前,我们先启动上一节搭建的eureka-server,两个服务都启动好以后,我们访问注册中心,可以看到:

说明我们服务注册成功!访问一下http://127.0.0.1:8764/hi?name=hornet

到此,eureka-client(服务发现)项目搭建成功。
