Spring boot and thymeleaf pagination and sorting - spring

Question

I am studying spring boot and making pet project and now I need do pagination and sorting. I am using thymeleaf in html page and I have some problem with Pageable and Sort field.
I have controller
#GetMapping
public String showAllClassrooms(Model model, Pageable page) {
Page<Classroom> classroomPage = classroomService.getAndSort(page);
model.addAttribute("classroomPage", classroomPage);
return "classrooms-page";
}
and Service method
#Transactional
public Page<Classroom> getAndSort(Pageable paging) {
long totalElement = count();
List<Classroom> classrooms = new ArrayList<>();
if (paging.getSort().toString().contains("Address")) {
classrooms = getAndSortByAddress(paging.getPageSize(), (int) paging.getOffset());
} else {
classrooms = getAndSortByCapacity(paging.getPageSize(), (int) paging.getOffset());
}
return new PageImpl<Classroom>(classrooms, paging, totalElement);
}
and naviagion in page
<nav aria-label="..." th:object="${classroomPage}">
<ul class="pagination justify-content-center">
<li class="page-item" th:classappend="*{(getNumber == 0 ? 'disabled' : '' )}">
<a class="page-link" th:href="#{/classrooms/(page=*{getNumber-1}, size = *{size}, sort=*{sort})}">«</a></li>
<li class="page-item" th:classappend="*{(getNumber == getNumber ? 'active' : '' )}">
<a class="page-link" th:text="*{getNumber} + 1" th:href="#{/classrooms/(page=*{getNumber}, sort=*{sort})}" ></a></li>
<li class="page-item" th:classappend="(*{getNumber} == *{getTotalPages}-1 ? 'disabled' : '' )">
<a class="page-link" th:href="#{/classrooms/(page=*{getNumber+1} , size = *{size} , sort=*{sort})}">»</a>
</li>
<li class="page-item">
<form action="#" method="get" th:action="#{/classrooms/}"
>
<div class="input-group">
<input class="w-25 p-1" type="text" name="page" th:value="${classroomPage.getNumber+1}">
<input type="hidden" name="size" th:value="${classroomPage.size}">
<input type="hidden" name="sort" th:value="${classroomPage.getSort}">
<span class="input-group-text" th:utext="${classroomPage.getNumber + 1}" ></span>
</div>
</form>
</li>
</ul>
</nav>
everything is working alright, but I have double direction in address field of browser, like this
http://localhost:8080/classrooms/?page=2&size=5&sort=Capacity:%20ASC:%20ASC:%20ASC:%20ASC:%20ASC:%20ASC:%20ASC:%20ASC
Thank you for you time, and sorry for my bad english :)
