问题：正常安装MongoDB后，java连接MongoDB进行测试，出现错误：缺少依赖包，已解决，文末含依赖包下载地址。

项目目录：

简易代码：

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

public class MongoDBJDBC{
   public static void main( String args[] ){
      try{   
    	  // 连接到 mongodb 服务
         MongoClient mongoClient = new MongoClient( "localhost" , 27017 );
       
         // 连接到数据库
         MongoDatabase mongoDatabase = mongoClient.getDatabase("db");  
         System.out.println("Connect to database successfully");
        
      }catch(Exception e){
        System.err.println( e.getClass().getName() + ": " + e.getMessage() );
     }
   }
}

运行报错：

Exception in thread "main" java.lang.NoClassDefFoundError: com/mongodb/connection/BufferProvider
	at MongoDBJDBC.main(MongoDBJDBC.java:8)
Caused by: java.lang.ClassNotFoundException: com.mongodb.connection.BufferProvider

解决方法：

下载依赖包：bson-3.8.2.jar和mongodb-driver-core-3.8.2.jar,添加到项目构建路径：

再次运行代码（成功！）：

九月 29, 2018 5:37:03 下午 com.mongodb.diagnostics.logging.JULLogger log
信息: Cluster created with settings {hosts=[localhost:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500}
