1. idea创建springboot父工程
File--》 New--》 Project...--》Spring Initializr--》Project sdk选择jdk版本一般是1.8,所以你要按照1.8版本才好使用springcloud》next--》修改一下Group为com.wlg.springcloud和Artifact为springcloud--》next--》弹框的顶部可以切换springboot的版本,我这里选的是2.3.1,在左边依赖列表中选择Web,在中间窗口选中Spring Web(有的idea是Spring Web Starter) --》 next--》Finish。
由于这个是主模块,所以我的pom.xml文件要修改一下packaging改成pom,把springcloud依赖放到dependencyManagement,其他子模块就可以继承springcloud的依赖:
