How to Use MySQL Connector/J 8.0.32.jar?
After installing MySQL Connector/J 8.0.32.jar, you can use it in your Java code to connect to MySQL databases and perform various operations.
Connection URL format
The connection URL is a string that specifies how to connect to a MySQL database using Connector/J. The general format of the connection URL is:
jdbc:mysql://[host1][:port1][,[host2][:port2]]...[/[database]][?propertyName1=propertyValue1[&propertyName2=propertyValue2]...]
The connection URL consists of several parts:
The prefix jdbc:mysql: indicates that the driver is Connector/J.
The host and port specify the address and port number of the MySQL server. You can specify multiple hosts and ports for load balancing and failover purposes, separated by commas.
The database is the name of the database to connect to. If omitted, no database is selected by default.
The properties are optional parameters that control various aspects of the connection, such as user name, password, SSL mode, character set, and more. You can specify multiple properties separated by ampersands (&).
Connection examples
Here are some examples of connection URLs using Connector/J:
ExampleDescription
jdbc:mysql://localhost:3306/test?user=root&password=secretConnects to the test database on localhost using port 3306, with user name root and password secret.
jdbc:mysql://db1.example.com,db2.example.com:3307/sales?user=sales&password=sales123&useSSL=trueConnects to the sales database on db1.example.com using port 3306 or db2.example.com using port 3307, with user name sales and password sales123, using SSL encryption.
jdbc:mysql://localhost/test?useUnicode=true&character Encoding=UTF-8Connects to the test database on localhost using port 3306, with default user name and password, using Unicode and UTF-8 character encoding.
To create a connection object using Connector/J, you need to use the DriverManager class and pass the connection URL as a parameter. For example:
import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class MySQLConnectionExample public static void main(String[] args) // Connection URL String url = "jdbc:mysql://localhost:3306/test?user=root&password=secret"; // Connection object Connection conn = null; try // Load the driver class Class.forName("com.mysql.cj.jdbc.Driver"); // Create the connection conn = DriverManager.getConnection(url); // Print the connection status System.out.println("Connection successful: " + conn); catch (ClassNotFoundException e) // Handle driver class not found exception e.printStackTrace(); catch (SQLException e) // Handle SQL exception e.printStackTrace(); finally // Close the connection if (conn != null) try conn.close(); catch (SQLException e) e.printStackTrace();
