MongoDB與Spring、Maven整合

最近在研究mongoDB的在項目中使用的優缺點，也一直在思考，作為nosql的經典之作的mongoDB ，能不能在一個項目中完全取代成熟優秀的關聯式資料庫的傑出代表mysql,作為資料存放區的介質；或者，需要將兩者結合起來使用，才能發揮他們最大的威力。
Spring與各種關聯式資料庫的ORM架構（如Hibernate/MyBatis）的整合方案非常成熟，也是我們在項目開發中最為常用的方式。本文介紹的是在Spring中如何使用spring-data-mongodb來簡化mongoDB資料庫的訪問工作。 建立maven項目，並引入spring-data-mongodb的依賴包，這裡我把我項目pom.xml檔案列出來。
