Formating errormessage in thymeleaf template

[Pieter Vandevelde]

Hi All
This is my first post on this forum, so don't shoot me if I posted in the wrong topic.
I have a springboot MVC app, which has a registerform, when there is wrong input from the user the controller add's an error message to the model which is then shown on the bottom of the page.
Everything is working fine, but for some reasson my message is concatenated all together.
I tried "\n", System.lineSeparator() and even knowing html is not redered, I also tried <br>, non of these worked.
When I print the errormessage to the console it's formatted corectly, so the prob is in my template.
I use a StringBuilder tobuild the message and then call the toString method when passing it to the model.
Anyone an idea how to solve my issue?

Welcome to the Ranch!

Can you show the part of your Thymeleaf template where you render this error?

 <div>
        <h3>
            <!--/*@thymesVar id="errorMessage" type="myApp"*/-->
            <div th:if="${errorMessage}">
                <span style="background-color: #99ccff" th:text="${errorMessage}"></span>
            </div>
        </h3>
    </div>

an example of something being appende to the errormessage:

 for (String emailS : repo.selectEmails()) {
     if (emailS.equalsIgnoreCase(user.getEmail())) {
         errorMessage.append("This e-mail is already registered.")
                    .append("\r\n")
                    .append("Did you forget your password?");
     }
 }

the ("\r\n") is the last thing I tried, I tried them separetly too, aswell as <br> and the System.lineSeperator()

I found a Thymeleaf tutorial online and poked around in it for a few minutes. Looks like your answer is here: Unescaped Text.

[Rob Spoor]

I think Paul is right. Thymeleaf escapes your input when you use th:text. Note that whitespace like line breaks don't matter because in HTML these show up as a single space. The <br> tag is the way to go as long as you tell Thymeleaf not to escape it.
