mongodb+spring +morphia完整版框架搭建

LemonSnm 2016-09-09

  • Morphia是一个开放源代码的对象关系映射框架,它对MongoDB数据库java版驱动进行了非常轻量级的对象封装,使得Java程序员可以随心所欲的使用对象编程思维来操纵MongoDB数据库,也让Java程序员可以从复杂数据库设计中脱离出来,从而将更多的精力投入到业务逻辑中去。Morphia是一个轻量级的类型安全的Java对象to/fromMongoDB库.Morphia提高了通过注解的方式来保存mongodbcollection。
  • @Id注释指示Morphia哪个字段用作文档ID。如果试图持久保存对象(其@Id注释的字段为null),则Morphia会自动生成ID值。@Entity@Entity注释是必需的。其声明了在专用MongoDB集合上该类作为文档将持久保存。在默认情况下,Morphia使用类名称来命名集合。@Embedded@Embedded注释说明Morphia将此对象实例嵌入到另一个对象中去。而不单独的放到一个MongoDB集合。@Reference@Reference注释说明对象是对另外一个集合中的文档的引用。在从MongoDB集合中加载对象时,Morphia遵循着这些引用来建立对象关系。@Indexed类属性标记@Indexed注释,表明为此属性增加索引。@Property类属性标记@Property注释,表明为此属性在MongoDB数据库取一个别名。@Transient类属性标记@Transient注释则表明这个字段将不被持久化到数据库。4.Morphia编程模型
  • 1.定义被持久类@EntityclassMyEntity{@IdObjectIdid;Stringname;}2.
  • 初始化morphiaMongomongo=newMongo("localhost");//连接到本地mongoDB数据库Morphiamorphia=newMorphia();morphia.mapPackage("MyEntity");//
  • 告诉Morphia映射哪些类Datastoreds=morphia.createDatastore(mongo,"myDB");//创建名为“myDB”数据库,
  • mongo最好使用单实例模式ds.ensureIndexes();//在标记为@Id的类属性上创建索引ds.ensureCaps();//设置默认的mongoDB集合容量3.保存被持久化类MyEntitye=...;ds.save(e);//将MyEntity对象持久化到mongoDB数据库中4.查询MyEntitye=ds.find(MyEntity.class).get();//通过类型取的第一个数据项MyEntitye=ds.find(MyEntity.class).field("name")

Datastore接口把Java对象保存到MongoDB或从MongoDB中访问Java对象提供了安全类型的方法。它提供了get/find/save/delete方法为你操作Java对象。

来看代码吧。

这里自己没有搭建集群分片,读写目前用的一个mongodb数据库。另外可以MongoVUE管理工具,比较好用。当然命令用习惯了,用命令也是一样。下载地址:http://www.baidu.com/link?url=IF-yXcmW-RgoE2hPr4kNGoPwSIkRljqJhPR_gOuEwZPloaUsI9V-t-iMTFN8eAQR

mongodb下载地址:https://www.mongodb.com/download-center安装搭建什么的比较简单。百度一下都有啦。这里就不做介绍了。基本环境算是搭建起来了。现在用下morphia的增删改查方法吧。

这里自己用的缓存,和一些工具类的使用,结合公司的一些写法。封装了了一下公共类的使用。如果需要搭建框架的朋友直接那过去用吧
