Spring Boot中@Controller与Thymeleaf视图正常运行但代码标红求助

我的Spring Boot应用启动后，@Controller可正常与Thymeleaf视图配合工作，但编写HTML文件时，Thymeleaf相关代码被标红，导致难以排查HTML错误。

控制器代码 #

package com.nikita.al_fp.controllers;

import com.nikita.al_fp.entity.Book;
import com.nikita.al_fp.entity.Person;
import com.nikita.al_fp.service.BookService;
import com.nikita.al_fp.service.PersonService;
import com.nikita.al_fp.util.BookValidator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;

@Controller
@RequestMapping("/book")
public class BookController {

    private final BookValidator bookValidator;
    private final PersonService personService;
    private final BookService bookService;
    public static final String BOOK_REDIRECT_PAGE = "redirect:/book";

    @Autowired
    public BookController(BookValidator bookValidator, PersonService personService, BookService bookService) {
        this.bookValidator = bookValidator;
        this.personService = personService;
        this.bookService = bookService;
        personService.startProgramProcessPerson();
        bookService.startProgramProcessBook();
    }

    @GetMapping
    public String selectBook(Model model) {
        model.addAttribute("books", bookService.findAll());
        return "/book/select_book";
    }
}

HTML视图代码 #

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

<div th:each="book : ${books}">
    <a th:href="@{/book/{id}(id=${book.getId()})}"
       th:text="${book.getName() + ', ' + book.getAuthor() + ', ' + book.getYear()}">book</a>
    <br/>
</div>

<br/>
<hr/>

<a href="/book/new">Add book</a>
<br>
<a href="/people">Show User List</a>

</body>
</html>
