如何解决ClassNotFoundException：com.mongodb.connection.BufferProvider？

我正在尝试编写简单的java代码，该代码在控制台上显示MongoDB集合。我已经在我的类路径中添加了mongodb-driver-3.0.0.jar。

I am trying to write simple java code which shows the MongoDB collections on console. I have added mongodb-driver-3.0.0.jar in my classpath.

但是当我尝试执行代码时，它会给我以下错误：数据库连接：

But when I try to execute the code, it is giving me following error at the line of Database connection:

线程main中的异常java.lang.NoClassDefFoundError：

以下是我的code snippet：

Following is my code snippet:

public static void main(String[] args) 
    {
        MongoClient mongoClient = new MongoClient("localhost", 27017); //Exception

        @SuppressWarnings("deprecation")
        DB db = mongoClient.getDB("mydb");
        System.out.println("Database connection successfull.");
        ...
        ...
    }

什么是问题在这里？我是否需要在类路径中添加另一个jar或存在一些版本问题？

What is the problem here? Do I need to add another jar in classpath or there is some version problem?
