Как повесить метод delete на кнопку в Thymeleaf

Question

Есть контроллер

package ru.hiik.documentsite.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import ru.hiik.documentsite.dao.DocumentRepo;
import ru.hiik.documentsite.models.Document;

@Controller
@RequestMapping("documents")
public class DocumentController {

    @Autowired
    DocumentRepo documentRepo;

    @GetMapping
    public String getAllDocuments(Model model){
        model.addAttribute("documents", documentRepo.findAll());
        return "document-page";
    }

    @RequestMapping("/create")
    public String createDocuments(Model model){
        model.addAttribute("document", new Document());
        return "create";
    }

    @PostMapping("/create/submit")
    public String submitDocument(@ModelAttribute Document document){
        documentRepo.save(document);
        return "redirect:../";
    }

    @DeleteMapping("/delete")
    public void deleteDocument(@RequestBody Document document){
        documentRepo.delete(document);
    }
}

Есть шаблон Thymeleaf

Подскажите, как правильно повесить метод delete на кнопку "Удалить"?

Answer 1

Используйте отправку данных через форму и метод POST

<div class="main">
    <div th:each="document:${documents}">
        <div class="card">
            <div class="card-body">
                <form action="/documents/delete" method="post">
                    <h5 class="card-title" th:text="${document.title}"/>
                    <p class="card-text" th:text="${document.body}"/>
                    <input type="hidden" value="${document}">
                    <button type="submit">Удалить</button>
                </form>
            </div>
        </div>
    </div>
</div>
