MySQL ConnectorJDBC 线程安全吗

MySQL Connector/JDBC是MySQL官方提供的Java编程语言的驱动程序，用于连接和操作MySQL数据库。在开发过程中，线程安全是一个非常重要的考虑因素，因为多线程环境下的并发访问可能会导致数据不一致或者其他问题。那么，MySQL Connector/JDBC是否线程安全呢？接下来我们将进行探讨。

java
import java.sql.*;
public class DatabaseThread extends Thread {
    private static final String URL = "jdbc:mysql://localhost:3306/test";
    private static final String USERNAME = "root";
    private static final String PASSWORD = "password";
    @Override
    public void run() {
        try {
            Connection connection = DriverManager.getConnection(URL, USERNAME, PASSWORD);
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery("SELECT * FROM users");
            while (resultSet.next()) {
                System.out.println(resultSet.getString("username"));
            }
            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) {
        // 创建多个线程
        Thread thread1 = new DatabaseThread();
        Thread thread2 = new DatabaseThread();
        // 启动线程
        thread1.start();
        thread2.start();
    }
}
