Hi there and welcome! In this unit, you’ll learn how to connect to an Atlas cluster by using the MongoDB Java driver.
I’m Xixi Zhang
MongoDB makes it easy for us to connect a Java application to an Atlas cluster. All we need is a connection string, the MongoDB Java driver, and an application.
By using the MongoDB Java driver, you can seamlessly integrate your Atlas cluster into a variety of applications.
For example, we can use Atlas to host data that’s delivered to users by using a REST API built with Java.
MongoDB is powerful on its own, but pairing it with a programming language like Java opens up even more possibilities. We’ll explore these possibilities throughout the course.
The lessons in this unit consist of video lectures followed by quiz questions or labs so that you can practice what you learned.
First, we’ll explain what MongoDB drivers are and how they are used to connect applications to MongoDB.
Then, we’ll install the MongoDB Java driver by using Maven. We’ll create a MongoClient instance in our Java code, and then connect to an Atlas cluster.
Finally, we will troubleshoot a few of the most common connection problems such as: Incorrect user credentials, network access issues, and incorrectly entered connection string.
Before you begin this unit, you should have a basic understanding of Java, the MongoDB database and document model, and Atlas.
You will also need to set up an Atlas account with a free tier cluster.
By the end of this unit, you will be able to install the MongoDB Java driver, use your connection string to connect your Java application to Atlas, and troubleshoot common connection errors.
Let's get started!
