Java网络商城项目 SpringBoot+SpringCloud+Vue 网络商城（SSM前后端分离项目）三（后台搭建）

一、开发环境

后端技术：

• 基础的SpringMvC、Spring 5.0和MyBatis3
• Spring Boot 2.0.4版本
• Spring Cloud最新版
• Finchley.SR1
• Redis-4,.0
• RabbitMQ-3.4
• Elasticsearch-5.6.8
• nginx-1.10.2
• FastDFS- 5.0.8
• MyCat
• Thymelcaf
• JWT

为了保证开发环境的统一，希望每个人都按照我的环境来配置∶

IDE:我们使用ldea

JDK:统一使用JDK1.8.151

项目构建: maven3.3.x

以上版本即可

二、工程的搭建

1、创建父工程

创建统一的父工程: leyou，用来管理依赖及其版本，注意是创建project，而不是moudle

2、引入依赖

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3、创建EurekaServer

（1）创建子工程（ly-registry）

（2）引入Eureka的依赖

  <dependencies>
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-serverartifactId>
        dependency>
  dependencies>

（3）编写启动类（并添加注解）

package com.leyou;

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

@EnableEurekaServer
@SpringBootApplication
public class LyRegistry {

    public static void main(String[] args) {

        SpringApplication.run(LyRegistry.class);

    }
