本教程主要详细讲解Spring Data MongoDB,它向MongoDB提供Spring Data平台的抽象.
MongoDB是基于文档的存储,以持久保存数据,并可用作数据库,缓存,消息代理等.
基础环境

| 技术 | 版本 |
|---|
| Java | 1.8+ |
| SpringBoot | 2.x.x |
| DataJPA | 2.x.x |
| MongoDB | 3.6.3-cmongo- |

配置支持MongoDB
—
- 在
/src/main/java/com/edurt/sli/slidmt目录下创建config目录,并在该目录下新建MongoDBConfig文件
