在多线程场景中，使用Tomcat JDBC DataSource对象的静态实例是否安全？

public class MyThread implements Runnable {
    private DataSource dataSource;

    public MyThread(DataSource dataSource) {
        this.dataSource = dataSource;
    }

    @Override
    public void run() {
        Connection connection = null;
        try {
            connection = dataSource.getConnection();
            // 使用连接执行数据库操作
        } catch (SQLException e) {
            // 处理异常
        } finally {
            if (connection != null) {
                try {
                    connection.close();
                } catch (SQLException e) {
                    // 处理异常
                }
            }
        }
    }
}

// 在多线程环境中创建和启动线程
DataSource dataSource = createDataSource(); // 创建DataSource实例
ExecutorService executorService = Executors.newFixedThreadPool(10); // 创建线程池
for (int i = 0; i < 10; i++) {
    executorService.execute(new MyThread(dataSource));
}
executorService.shutdown();
