测试代码：

package com.couchdb;

import java.net.MalformedURLException;

import org.ektorp.CouchDbConnector;
import org.ektorp.CouchDbInstance;
import org.ektorp.http.HttpClient;
import org.ektorp.http.StdHttpClient;
import org.ektorp.impl.StdCouchDbConnector;
import org.ektorp.impl.StdCouchDbInstance;

public class CouchDBTest {

	public static void main(String[] args) throws MalformedURLException {
		
		HttpClient httpClient = new StdHttpClient.Builder().url("http://192.168.11.124:5984").build();
		CouchDbInstance dbInstance = new StdCouchDbInstance(httpClient);
		CouchDbConnector db = new StdCouchDbConnector("mydatabase", dbInstance);
		db.createDatabaseIfNotExists();

		Sofa sofa = db.get(Sofa.class, "id_1");
		if(sofa != null) db.delete(sofa);
		
		sofa = new Sofa();
		sofa.setId("id_1");
		sofa.setColor("red");
		db.create(sofa);
		
		Sofa tmpSofa = db.get(Sofa.class, "id_1");
		System.out.println(tmpSofa.getRevision() + " : " + tmpSofa.getColor());
		tmpSofa.setColor("blue");
		db.update(tmpSofa);
		tmpSofa = db.get(Sofa.class, "id_1");
		System.out.println(tmpSofa.getRevision() + " : " + tmpSofa.getColor());
	}
}

CouchDB4J：

package com.yuxipacific;

import java.util.List;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.Session;
import com.fourspaces.couchdb.ViewResults;

public class CouchDB4J {

	public static void main(String[] args) {
		
		Session session = new Session("192.168.11.124",5984);
		Database database = session.getDatabase("mydatabase");
		ViewResults vr = database.getAllDocuments();
		System.out.println(vr.toString());
		
		JSONArray jsonData = (JSONArray)vr.get("rows");
		for (Object object : jsonData) {
			JSONObject jsonObject = (JSONObject) object;
			System.out.println(jsonObject.get("key"));
		}
		
		List<Document> documents = vr.getResults();
		for (Document document : documents) {
			System.out.println(document.toString());
		}
	}
