Java Mongodb BasicDBObject Example

Storing Java Object in Mongodb

Java Mongodb driver basically gives you to options when storing data in MongoDB . Either subclass BasicDBObject which is the general database object, or implement the DBObject interface.
Example
BasicDBObject contact = new BasicDBObject();
contact.put("name", "pretech");
contact.put("address", "bangalore");
or
public class xxx extends BasicDBObject and put the values

Create a Maven project and add below dependency in pom.xml

<dependency>
   <groupId>org.mongodb</groupId>
   <artifactId>mongo-java-driver</artifactId>
   <version>3.1.1</version>
  </dependency>

Create a Java class 

package com.vinod.mongo.crud;

import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.Mongo;
import com.mongodb.MongoException;

public class MongoBasicDbObjectExample {

 public static void main(String[] args) {
  try {
           System.out.println("BasicDBObject insert example...");
   // Creating mongoinstance
           Mongo mongo = new Mongo("localhost", 27017);
   // Creating database instance
           DB db = mongo.getDB("mydb");

   // Creating collection object
           DBCollection collection = db.getCollection("customer");

           Customer customer = new Customer("vinod", "se", "wipro", "bangalore");

           collection.insert(customer);

   // Retrieving collection details
           DBCursor cursorDoc = collection.find();
           while (cursorDoc.hasNext()) {
               System.out.println("Address details " + cursorDoc.next());
           }
           } catch (MongoException e) {
                    e.printStackTrace();
           }
      }

}

class Customer extends BasicDBObject {
 private static final long serialVersionUID = 1L;
 public String name;
 public String designation;
 public String employer;
 public String address;

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public String getDesignation() {
  return designation;
 }

 public void setDesignation(String designation) {
  this.designation = designation;
 }

 public String getEmployer() {
  return employer;
 }

 public void setEmployer(String employer) {
  this.employer = employer;
 }

 public String getAddress() {
  return address;
 }

 public void setAddress(String address) {
  this.address = address;
 }

 public static long getSerialversionuid() {
  return serialVersionUID;
 }

 public Customer() {
 }

 public Customer(String name, String designation, String employer, String address) {
  put("name", name);
  put("designation", designation);
  put("employer", employer);
  put("address", address);

 }

}

Output

Address details { "_id" : { "$oid" : "568f6d92f5d3c83e9d64a8b5"} , "name" : "vinod" , "designation" : "se" , "employer" : "wipro" , "address" : "bangalore"}
