public class DBUtils {
    private static DataSource dataSourcec3p0;
    static {
        try {
            dataSourcec3p0 = new ComboPooledDataSource("shoppingc3p0");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public static Connection getConnectionc3p0() throws IOException,SQLException
    {
        // 建立连接
        Connection connection = dataSourcec3p0.getConnection();
        return connection;
    }
    
｝
