springboot初搭建（一）

1.登录http://start.spring.io/，界面如下：

 

然后点击绿色的按钮下载。

2.打开idea，选择你解压的文件，导入

3.配置maven仓库（如果本地没有的话，请下载一个并配置环境变量）

 

4.在idea右侧栏咱如图所示操作，加载jar包，当出现右边的图  则编译成功

                                      

注意：如果出现多口号冲突，则在application.properties中修改端口号，如下图所示：

5.这样一个项目就搭建好了，找到SpringBootDemoApplication（入口文件），右键启动，则可以进入系统了。
