如何在Java中的单个服务中调用多个URL？

Question

DBConn dBConn = new DBConn();
PreparedStatement prepareStatement;

Connection con = dBConn.getDBConnectionForPro();
prepareStatement = con.prepareStatement("SELECT * FROM TBL_MASCONFIGTTB WHERE SERVICE_NAME=GUPSHUP AND VALUE=TRUE");

if (prepareStatement.equals("true")) {
    System.out.println(GenerateLinkDaoImpl.sendOTP("90xxxxxxxx", smsBody));
}
else {
    System.out.println(GenerateLinkDaoImpl.SendSms("90xxxxxxxx", smsBody));
}

Answer 1

您不能在PreparedStatement上使用布尔值，而需要首先使用ResultSet。 尝试使用下面的代码。

DBConn dBConn = new DBConn();
PreparedStatement prepareStatement = null;
ResultSet rs = null;

Connection con = dBConn.getDBConnectionForPro();
prepareStatement = con.prepareStatement("SELECT * FROM TBL_MASCONFIGTTB WHERE SERVICE_NAME=GUPSHUP AND VALUE=TRUE");
rs = prepareStatement.executeQuery();

if (rs.next()) {
    System.out.println(GenerateLinkDaoImpl.sendOTP("90xxxxxxxx", smsBody));
}
else {
    System.out.println(GenerateLinkDaoImpl.SendSms("90xxxxxxxx", smsBody));
}
