public class TransactionInfoService implements DataInterface {
    private String info;
    private JdbcTemplate jdbcTemplate;

    public void connect() {
        // Connect To Database
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        // dataSource.setUrl("jdbc:mysql://localhost:3306/dashboard");
        dataSource.setUrl("jdbc:mysql://xx.1.1.xx:3306/dashboard");
