Print List object from Spring Boot controller to view (HTML)

Question

This is my controller mapping, I need to print all the properties of the list objects in my view.

@RequestMapping(value = "/get" , method = RequestMethod.GET)
@ModelAttribute("todolist")
public List<Todo> getuser() {
    return  (List<Todo>) todoRepository.findAll();
}

This is my View, and a link to my GitHub project.

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head lang="en">
    <head>
    </head>
<body>
<table>
    <tr th:each="message : ${todolist}">
        <td th:text="${todolist.title}">Title</td>
        <td th:text="${todolist.description}">Description</td>
    </tr>
</table>
</body>
</html>

You need to use message instead of todolist

<tr th:each="message : ${todolist}">
    <td th:text="${message.title}">Title</td>
    <td th:text="${message.description}">Description</td>
</tr>

Because th:each will iterate through the list of todolist and puts the value inside message property. Means message is your variable name for one element of the list. Would be better to call it todo for example.

I'm trying to get data from mysql and render it in my HTML view. I fetched it as object list and got stuck here. I don't know how to send these objects to my view for printing it. I can submit the data from html to database from the same controller. The controller works well. New to Stack overflow sorry :P.
