Using the Morphia framework to manipulate MongoDB

1. Install MongoDB under Mac

sudo brew update

sudo brew install MongoDB

sudo brew services MongoDB start

2. Create a mapping class

Package Mongodbdemo;import Org.mongodb.morphia.annotations.entity;import org.mongodb.morphia.annotations.Id; Use Morphia's annotation to annotate @entitypublic class User {    @Id    private long Id;        private String name;    Private Boolean sex;    private int age;    Private String address;        Public user () {    } public    user (long ID, string name, Boolean sex, int age, string address) {        super ();        This.id = ID;        this.name = name;        This.sex = sex;        This.age = age;        this.address = address;    }    Getter, setter        @Override public    String toString () {        return this.id + "#" + THIS.name + "#" + This.age + "# "+ This.sex +" # "+ this.address;    }}

3. Test code

Package Mongodbdemo;import Org.mongodb.morphia.datastore;import Org.mongodb.morphia.morphia;import Com.mongodb.mongoclient;public class Demo {public        static void Main (string[] args) {        Morphia Morphia = new Morphia ();    Tell Morphia where to find your class    //Can make multiple calls to different packages or classes    morphia.mappackage ("Mongodbdemo");    Create Datastore, and connect to the specified database    //datastore has two parameters, the first one to connect to MongoDB, and the second is the name of the database.    final Datastore Datastore = Morphia.createdatastore (new mongoclient ("localhost"), "morphia_example");    Datastore.ensureindexes ();        Final User user = new User (0, "Zhansan", false,20, "Home");    Datastore.save (user);}        }

After running, view the database
