学习版本

创建父工程

父工程pom文件

创建父工程后mvn install发布到本地仓库供子工程继承。

Maven 的dependencyManagement 和dependencies

微服务服务提供者

创建cloud-provider-payment8001微服务提供者支付Module模块。

创建新模块主要步骤：

建module
改POM
写YML
主启动
业务类

            return new CommonResult(444,"没有对应记录,查询ID: "+id,null);
        }
    }
}

微服务服务消费者

新建cloud-comsumer-order80 服务消费者，通过RestTemplate访问服务提供者。服务消费者使用的不是视频上的80端口，而是8080端口。

工程重构

将服务提供者和服务消费者的公用entity抽取到一个通用cloud-api-commons工程。供所有工程通用。
