Spring Thymeleaf Whitelabel-CodePudding

I was trying to build a simple spring web app. The app works correctly but I am not being able to connect to the web server when using a Thymeleaf template.

The controller class is the following one:

@Controller() public class BookController { 
private final BookRepository bookRepository;
public BookController(BookRepository bookRepository) {
    this.bookRepository = bookRepository;
}

@GetMapping("/books")
public String getBooks(Model model){
    model.addAttribute("bookList", bookRepository.findAll());
    return "books/list";
}
}

The HTML template:

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8"/>
    <title>Spring Web App</title>
</head>
<body>
<h1>Book List</h1>

<table>
    <tr>
        <th>ID</th>
        <th>Title</th>
        <th>Publisher</th>
    </tr>
    <tr th:each="book : ${bookList}">
        <td th:text="${book.id}">123</td>
        <td th:text="${book.title}"> Spring in Action</td>
        <td th:text="${book.isbn}">Wrox</td>
    </tr>
</table>

</body>
</html>

My directory tree is the following one:

I don´t get any error or exception, I just get the following blank page:

I´ve tried both '@GetMapping' and '@RequestMapping' and followed a few tutorials but i can´t figure out what is the issue. I would be so thankful if someone could help me with this.

I managed to map the error and I only get the status code: try your folder structure like this in the screen short

CodePudding user response：

The problem was that the package controller was over the rest while the IDE interpretated like it was at the same level.

I just had to move the package to the same level and it works.
