- In this Demo ,"A new Student document is created with properties nad added to the student database".

import java.util.HashMap;
import java.util.Map;
import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.Session;
public class CouchDBTest {
/*These are the keys of student document in couch db*/
public static final String STUDENT_KEY_NAME ="name";
public static final String STUDENT_KEY_MARKS ="marks";
public static final String STUDENT_KEY_ROLL="roll";
public static void main(String[] args){
/*Creating a session with couch db running in 5984 port*/
Session studentDbSession = new Session("localhost",5984);
/*Selecting the 'student' database from list of couch database*/
Database studentCouchDb = studentDbSession.getDatabase("student");
/*Creating a new Document*/
Document newdoc = new Document();
/*Map for list of properties for the new document*/
Map<String , String> properties = new HashMap<String,String>();
properties.put(STUDENT_KEY_NAME, "saan");
properties.put(STUDENT_KEY_MARKS, "67");
properties.put(STUDENT_KEY_ROLL, "12");
/*Adding all the properties to the new document*/
newdoc.putAll(properties);
/*Saving the new document in the 'student' database */
studentCouchDb.saveDocument(newdoc);
}
}
- We can open the Futon and verify that the document is added to "student" Database.The screenshot,
