从零开始构造一个微服务

创建一个 spring boot 的程序

目录结构如下

wangchunye@wangchunye hello-micro-service$ tree
.
├── pom.xml
└── src
    ├── main
    │   ├── java
    │   │   └── wcy123
    │   │       └── org
    │   │           └── hello
    │   │               ├── HelloServerStarter.java
    │   │               └── SayHello.java
    │   └── resources
    └── test
        └── java
