MySQL Connector Java Maven Dependency

MySQL Connector/J is the official JDBC driver for MySQL. It provides a standard Java interface to connect to MySQL databases. In this tutorial, we will cover how to include the MySQL Connector/J as a Maven dependency, how to download the JAR file manually, and how to find the latest version of the Maven dependency.

Adding MySQL Connector/J as a Maven Dependency

If you are using Maven to manage your project's dependencies, you can easily include the MySQL Connector/J in your pom.xml file. Here’s how you can do it:

Step 1: Add Dependency to pom.xml

To add the MySQL Connector/J to your Maven project, include the following dependency in your pom.xml file:

                <dependency>
                    <groupId>com.mysql</groupId>
                    <artifactId>mysql-connector-j</artifactId>
                    <version>9.0.0</version> <!-- Use the latest version available -->
                </dependency>
            

Example pom.xml

Below is an example of a complete pom.xml file with the MySQL Connector/J dependency:

    <project xmlns="http://maven.apache.org/POM/4.0.0" 
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.example</groupId>
        <artifactId>myapp</artifactId>
        <version>1.0-SNAPSHOT</version>
        
        <dependencies>
            <dependency>
                <groupId>com.mysql</groupId>
                <artifactId>mysql-connector-j</artifactId>
                <version>9.0.0</version>
            </dependency>
        </dependencies>

        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.8.1</version>
                    <configuration>
                        <source>21</source>
                        <target>21</target>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </project>

Finding the Latest Version of MySQL Connector/J

To ensure you are using the latest version of MySQL Connector/J, you can check the Maven Central Repository or the official MySQL Connector/J page. Here's how to find the latest version:

Step 1: Visit Maven Central Repository

1. Go to Maven Central Repository.
2. In the search bar, type mysql mysql-connector-j and press Enter.
3. You will see a list of available versions. The latest version will be at the top of the list.

Step 2: Visit MySQL Connector/J Page

1. Go to the official MySQL Connector/J page.
2. Click on the "Download" link to see the latest versions available for download

Downloading the MySQL Connector/J JAR File Manually

If you are not using Maven or want to download the JAR file manually, follow these steps:

Step 1: Visit the MySQL Connector/J Website

Go to the official MySQL Connector/J page: https://dev.mysql.com/downloads/connector/j/

Step 2: Download the JAR File

1. On the MySQL Connector/J page, click on the "Download" link.
2. Choose the version of the driver you want to download (preferably the latest one).
3. Download the JAR file to your local machine.

Step 3: Add the JAR to Your Project

1. Copy the downloaded JAR file to your project's lib directory.
2. Add the JAR file to your project's classpath. This can usually be done in your IDE (like IntelliJ IDEA or Eclipse) by right-clicking the JAR file and selecting the option to add it to the project's classpath.

Example Usage

Here's a simple Java program that demonstrates how to connect to a MySQL database using the JDBC driver:

import java.sql.Connection;
            import java.sql.DriverManager;
            import java.sql.ResultSet;
            import java.sql.Statement;
            
            public class MySQLExample {
                public static void main(String[] args) {
                    String url = "jdbc:mysql://localhost:3306/mydatabase";
                    String user = "myuser";
                    String password = "mypassword";
            
                    try {
                        Connection conn = DriverManager.getConnection(url, user, password);
                        Statement stmt = conn.createStatement();
                        ResultSet rs = stmt.executeQuery("SELECT VERSION()");
            
                        if (rs.next()) {
                            System.out.println(rs.getString(1));
                        }
            
                        rs.close();
                        stmt.close();
                        conn.close();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }

In this example, replace mydatabase, myuser, and mypassword with your actual database name, username, and password.

Conclusion

Adding the MySQL Connector/J to your project is straightforward, whether you are using Maven or downloading the JAR file manually. By following the steps outlined above, you can easily set up the MySQL Connector/J and start interacting with your MySQL database from your Java applications.
