使用Morphia架構操作mongodb

標籤：

1.  mac 下 安裝mongodb

sudo brew update

sudo brew install mongodb

sudo brew services mongodb start

 

2.  建立映射類

package mongodbDemo;import org.mongodb.morphia.annotations.Entity;import org.mongodb.morphia.annotations.Id; //利用morphia的annotation進行註解@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.  測試代碼

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();    // 告訴Morphia在哪裡找到你的類    // 可以為不同的包或者類進行多次的調用    morphia.mapPackage("mongodbDemo");    //建立datastore，並串連到指定資料庫    //datastore有兩個參數，第一個用來串連到MongoDB，第二個是資料庫的名字。    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);        }}

運行後，查看資料庫
