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 documents = vr.getResults();

for (Document document : documents) {

System.out.println(document.toString());

}

}
