一、在pom中添加依赖
<dependencies><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.33</version></dependency></dependencies>
然后同步一下
二、编写代码
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;public class Test {public static void main(String[] args) {Connection connection = null;String url = "jdbc:mysql://localhost:3306/test";String user = "root";String password = "root";try {Class.forName("com.mysql.cj.jdbc.Driver");connection = DriverManager.getConnection(url, user, password);} catch (Exception e) {System.out.println("Exception." + e.getMessage());} finally {// Close the connectionif (connection != null) {try {System.out.println("Success to connection.");connection.close();} catch (SQLException e) {System.out.println("Failed to close connection.");e.printStackTrace();}} else {System.out.println("Failed to connection.");}}}
}
