mongomongo | Java ODM framework for MongoDB | SQL Database library

I suppose you use it in a standard Servlet Container like Tomcat,Jetty. In order to make MongoMongo work properly, you will write a filter like follows(the core code is in init.The name of filter as yourself). and then modify your web.xml file,add your filter to web.xml. MongoMongo configuration can be done through a yaml file that specifies your options and database sessions. The normal configuration is as follows, which sets the default session to "127.0.0.1:27017" , provides a single database in that session named "wow", put documents in com.example.document package. Documents are the core objects in MongoMongo and any object that is to be persisted to the database must extends net.csdn.mongo.Document. The representation of a Document in MongoDB is a BSON object that is very similar to a Java Map or JSON object. But cause of the rigid grammar in Java,it's a really tough thing to operate MongoDB using MongoDB Java Driver. Extends net.csdn.mongo.Document will make your document more powerful and just like you are using a ORM. Documents can be stored in their own collections in the database, or can be embedded in other Documents n levels deep. You can configure your document in 'static block'.As a Javaer maybe you prefer using Annotation,but 'static block' is more flexible. Annotation have too much limitation,for example,can not hold a complex object. storeIn("blogs") means you store you data in 'blogs' collection when using Blog. You can configure your document in 'static block'.As a Javaer maybe you prefer using Annotation,but 'static block' is more flexible. Annotation have too much limitation,for example,can not hold a complex object. then MongoMongo will create a index for name field called ssh_index. MongoMongo will save userName as _id in MongoDB. ###Fields Even though MongoDB is a schemaless database, most usage will be with web applications where form parameters always come to the server as strings. MongoMongo provides an easy mechanism for transforming these strings into their appropriate types through the definition of fields in your document. And the other benefit is ,you can manipulate a object field instead of a Map key. As we know,it's hard to operate Map in Java.
