MongoDB副本集（Java）

还是蛮简单的，驱动把任务全部做掉了

package com.djhu.mongodb.test;

import java.util.Arrays;

import org.bson.Document;

import com.mongodb.MongoClient;
import com.mongodb.ServerAddress;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;

public class ReplTest
{
	private static void testInsert() 
	{
		MongoClient mongoClient = new MongoClient(Arrays.asList(
				   new ServerAddress("172.16.172.4", 27017),
				   new ServerAddress("172.16.172.4", 27018),
				   new ServerAddress("172.16.172.4", 27019)));

		MongoDatabase db = mongoClient.getDatabase("test");
		MongoCollection collection = db.getCollection("person");
		
		Document doc = new Document();
		doc.put("name", "tuzi");
		doc.put("age", 27);
		doc.put("sex", "Female");
		collection.insertOne(doc);
	}

	public static void main(String[] args)
	{
		testInsert();
	}
}

如果遇到下面的错误，是因为用了localhost作为replSet的地址，重新config一下就好了
