Thymeleaf cannot parse URL query parameters

Question

I'm using Thymeleaf version 2.1.4 and I want to print a string when sending query parameters to the URL. But it prints a string object, like this [Ljava.lang.String;@767a8ed5. I try to print it like this in HTML:

<p th:text="${param.message}"></p>

The URL is like this:

http://localhost:8000/about?message=This is about page.

Appreciate the error in my code and hope for help.

Answer 1

The Param object returns an array of strings for each parameter, even if the parameter has only one value, which is why you see the object reference [Ljava.lang.String;@767a8ed5. You can access the first element of the array using indexing like this:

<p th:text="${param.message[0]}"></p>
