mongodb+spring +morphia完整版框架搭建

• 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/from MongoDB 库.Morphia 提高了通过注解的方式 来保存mongodb collection。

• @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 @Entity  classMyEntity {  @Id  ObjectId id; String name;  }  2.
• 初始化morphia  Mongo mongo = new Mongo("localhost");//连接到本地mongoDB数据库  Morphiamorphia = new Morphia();  morphia.mapPackage("MyEntity");//
• 告诉Morphia映射哪些类 Datastore ds = 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  MyEntity e = ...;  ds.save(e);//将MyEntity对象持久化到mongoDB数据库中  4. 查询  MyEntity e =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。

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
