+# spring-boot-demo-mongodb
+
+> 此 demo 主要演示了 Spring Boot 如何集成 MongoDB，使用官方的 starter 实现增删改查。
+
+## 注意
+
+作者编写本demo时，MongoDB 最新版本为 `4.1`，使用 docker 运行，下面是所有步骤：
+
+1. 下载镜像：`docker pull mongo:4.1`
+2. 运行容器：`docker run -d -p 27017:27017 -v /Users/yangkai.shen/docker/mongo/data:/data/db --name mongo-4.1 mongo:4.1`
+3. 停止容器：`docker stop mongo-4.1`
+4. 启动容器：`docker start mongo-4.1`
