eureka 服务搭建

1.新建一个springboot的项目。
2.添加pom.xml 内容：

<?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"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

3.添加配置文件 application.yml

# server (eureka 默认端口为：8761)
server:
  port: 9999

# spring
spring:
  application:
    name: comm-eku

# eureka
eureka:
  client:
    # 是否注册到eureka
    register-with-eureka: true
    # 是否从eureka获取注册信息
    fetch-registry: false
    availability-zones:
      honghu: honghuZone
      #Eureka Server注册服务的地址
    service-url:
      honghuZone: http://honghu:123456@localhost:8761/eureka/
      defaultZone: http://honghu:123456@localhost:8761/eureka/
  instance:
    prefer-ip-address: true
    hostname: localhost
    metadataMap:
      zone: honghuZone
      user: ${security.user.name}
      password: {security.user.password}

  # 指定环境
  environment: dev
  #指定数据中心
  datacenter: honghu
  # 关闭自我保护模式
  server:
    enable-self-preservation: false
  #设置清理无效节点的时间间隔，默认60000，即是60s
    eviction-interval-timer-in-ms: 60000

# 服务认证
security:
  basic:
    enabled: true
  user:
    name: honghu
    password: 123456

management:
  security:
    enabled: false



4.给主类添加注解：
package com.boce.dfs;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.RequestMapping;

@ComponentScan(value = "com.boce")
@EnableEurekaServer
@SpringBootApplication
public class CommEkuApplication {

@RequestMapping("/hello")
private String greeting() {
return "Hello World!";
}

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





package com.boce;

import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

/**
* Created by gjp on 2017/11/7.
*/
@Component
@Configuration
public class ConfigBase {

    @LoadBalanced
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}






package com.boce.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.client.RestTemplate;

import javax.annotation.Resource;

/**
* Created by gjp on 2017/11/7.
*/

@Controller
public class DemoController {

    @Resource
    private RestTemplate restTemplate;

    @ResponseBody
    @RequestMapping("/demo/test")
    public String test(){
        System.out.println("test.................");
        return "test";
    }
}
