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
Java1.8+
SpringBoot2.x.x
DataJPA2.x.x
MongoDB3.6.3-cmongo-

创建项目


  • 初始化项目
mvn archetype:generate -DgroupId=com.edurt.sli.slidmt -DartifactId=spring-learn-integration-datajpa-mongodb-template -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false
  • 修改pom.xml增加mongodb的支持

配置支持MongoDB


  • /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

  • 在resources资源目录下创建一个application.properties的配置文件,内容如下

custom.mongodb.database=test

操作MongoDB数据


  • /src/main/java/com/edurt/sli/slidmt目录下创建model目录,并在该目录下新建MongoDBModel文件
