前言:
环境描述:
docker部署的consul
在搭建工程中，试过很多种玩法，行得通与不通，都去了解下，本文章提供的肯定是完善的一种模式。搭建中会遇到一些错误.
比如:
Connect to localhost:8500 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] f
其实打开浏览器访问等都是可以的，那么为什么项目中启动会报此错误呢。

这个时候，先不要忙着觉得是不是docker什么端口，宿主机什么通不通，什么防火墙端口之类的，直接忽略，这不浏览器访问都正常，那就先从项目中下手。
1.直接创建一个单独项目，启动正常，看来就是版本整合的问题了，切记，springboot+cloud整合时候，版本问题一定要注意，可以网上找资料看下版本对应。
单独测试项目如下:

=======main启动========
package com.king;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class clouddemoApplication {
public static void main(String[] args) {
SpringApplication.run(clouddemoApplication.class, args);
}
}
=====pom配置======

二：完整简单父子工程实例:
2.1搭建父工程

2.2创建好后，删除src目录:

父工程pom文件如下:

下一步选择初始化加载的一些引入，先什么都不选，后面自己加。接着在下一步，

至此：搭建完毕，子工程代码如下:
========main=======
package com.king;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WorldCloudAdminApplication {
public static void main(String[] args) {
SpringApplication.run(WorldCloudAdminApplication.class, args);
}
}
