No data insertion to Html Table View

Viewed 18

Hello I have a mail batch and inside the mail text I have an html block. I have a table and inside I am giving data with a for loop. But I want to add inside not only one row of data, but also if there are more records I also want to include them. I am adding screenshot and code below. When you look at the pictures it will be more clear I think. Thank you from now for your advices.

 public String createMailBody(List<VposNotificationBatchDto> notificationList) {

    String mailBody = "Merhaba,<br/><br/>Güvenlik Raporu için günlük işlem sayıları detayları aşağıdaki gibidir.";
    String errorBody = "errorBody";
    mailBody += errorBody;
    mailBody += "<br/><br/><br/>";

    mailBody += "<html><head><style>table{font-family: arial, sans-serif;border-collapse: collapse;width: 75%;}th{background-color: #9A9A9A;}";
    mailBody += "td,th{border: 1px solid #dddddd;text-align: left;padding: 8px;}tr:nth-child(even){background-color: #dddddd;}</style>";
    mailBody +=  "</head><body><h3>Job Çalışma Detayları : </h3><table><tr><th>MID</th><th>MD STATUS</th><th>BIN</th><th>COUNT</th><th>RATIO</th><th>MERCHANT NAME</th></tr>";

    for (int i = 0; i < notificationList.size(); i++) {

        mailBody += "<tr><td>" + notificationList.get(i).getMid() + "</td>";
        mailBody += "<td>" + notificationList.get(i).getMdStatus() + "</td>";
        mailBody += "<td>" + notificationList.get(i).getBin() + "</td>";
        mailBody += "<td>" + notificationList.get(i).getCount() + "</td>";
        mailBody += "<td>" + notificationList.get(i).getRatio() + "</td>";
        mailBody += "<td>" + notificationList.get(i).getMerchantName() + "</td></tr>";

        mailBody += endOfHtmlString;
        //mailBody += "<br/><br/><br/><br/>";
        //mailBody += createMetricDetails(vposNotificationBatchDtoList,i);

        String currentMailSubject = batchProps.getJobProps().get(jobName).getAlertProps().getMailSubject();

        if (severity == Constants.SEVERITY_SUCCESS) {
            mailBody = mailBody.replace("th{background-color: #9A9A9A;}","th{background-color: #5FA8CC;}");
            mailBody = mailBody.replace("errorBody","");
        } else if (severity == Constants.SEVERITY_ERROR) {
            mailBody = mailBody.replace("th{background-color: #9A9A9A;}","th{background-color: #DE0202;}");
            mailBody = mailBody.replace("errorBody","<br/><br/><br/><div style=\"width: 75%;\">"
                    + "<h4 style=\"background-color:yellow; color:#701500; border: 1px solid\">Lütfen aşağıda belirtilen "
                    + "metrikleri kontrol ediniz : <br/><br/>" + reportErrorMessage + "</h4></div>");
        } else if (severity == Constants.SEVERITY_WARNING) {
            mailBody = mailBody.replace("th{background-color: #9A9A9A;}","th{background-color: #E96A06;}");
            mailBody = mailBody.replace("errorBody","<br/><br/><br/><div style=\"width: 75%;\">"
                    + "<h4 style=\"background-color:yellow; color:#701500; border: 1px solid\">Lütfen aşağıda belirtilen metrikleri "
                    + "kontrol ediniz : <br/><br/><h3>" + reportErrorMessage + "</h4></div>");


            break;
        }
    }

    mailBody += endOfHtmlString;

    return mailBody;
}
