springcloud实战篇二之Eureka-client(服务提供者)创建

上篇已经搭建好了Eureka客户端,接下来为大家演示如何把利用Eureka-client把服务提供者注册进Eureka-server

下图为工程的目录结构

接下来再贴出主要的代码,其中简单的业务逻辑我就不贴了

1.application.yml文件

server:
  port: 8001
  
mybatis:
  config-location: classpath:mybatis/mybatis.cfg.xml        # mybatis配置文件所在路径
  type-aliases-package: com.yxf.springcloud.entities    # 所有Entity别名类所在包
  mapper-locations:
  - classpath:mybatis/mapper/**/*.xml                       # mapper映射文件
    
spring:
   application:
    name: MICROSERVICECLOUD-DEPT                        #对外暴露的服务(微服务)
   datasource:
    type: com.alibaba.druid.pool.DruidDataSource            # 当前数据源操作类型
    driver-class-name: org.gjt.mm.mysql.Driver              # mysql驱动包
    url: jdbc:mysql://localhost:3306/clouddb1              # 数据库名称
    username: root
    password: 123456
    dbcp2:
      min-idle: 5                                           # 数据库连接池的最小维持连接数
      initial-size: 5                                       # 初始化连接数
      max-total: 5                                          # 最大连接数
      max-wait-millis: 200                                  # 等待连接获取的最大超时时间
      
eureka:
  client: #客户端注册进eureka服务列表内
    service-url: 
      defaultZone: http://localhost:1001/eureka
  instance:
    instance-id: 127.0.0.1    
    prefer-ip-address: true     # 访问路径可以显示IP地址     
 
info: 
  app.name: yxf-mymicroservicecloud
  company.name: www.yxf.com
  build.artifactId: $project.artifactId$
  build.version: $project.version$

2.pom.xml文件

3.服务启动类

package com.yxf.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

import com.yxf.springcloud.EurekaServer1001;

/**
 * EurekaServer服务器端启动类,接受其它微服务注册进来
 * 
 * @author yangxf  
 */
@SpringBootApplication 
@EnableEurekaServer    //表明这个eureka的服务端
public class EurekaServer1001
{
	public static void main(String[] args)
	{
		SpringApplication.run(EurekaServer1001.class, args);
	}
}
