Thymeleaf将参数从html发送到控制器

问题内容：

我是Thymeleaf的新手。我正在尝试创建简单的Crud应用程序。我正在尝试删除按钮上的客户类的对象。如何使用Thymeleaf将参数（例如-
id）设置为调用deleteUser的方法。这是我的控制器。

package controllers;

//imports


@Controller
public class WebController extends WebMvcConfigurerAdapter {

    @Autowired
    private CustomerDAO customerDAO;

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/results").setViewName("results");
    }

    //show all users
    @RequestMapping(value="/users", method=RequestMethod.GET)
    public String contacts(Model model) {
        model.addAttribute("users",customerDAO.findAll());
        return "list";
    }

    //show form
    @RequestMapping(value="/users/add", method=RequestMethod.GET)
    public String showForm(Customer customer) {
        return "form";
    }

    //add user
    @RequestMapping(value="/users/doAdd", method=RequestMethod.POST)
    public String addUser(@RequestParam("firstName") String firstName,
                           @RequestParam("lastName") String lastName,
                           @RequestParam("lastName") String email) {
        customerDAO.save(new Customer(firstName, lastName, email));
        return "redirect:/users";
    }

    //delete user
    @RequestMapping(value="users/doDelete/{id}", method = RequestMethod.POST)
    public String deleteUser (@PathVariable Long id) {
        customerDAO.delete(id);
        return "redirect:/users";
    }
}

这是我的看法。

    <tr>
        <th>Id</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Email</th>
        <th>Action</th>
    </tr>
    <tr th:each="user : ${users}">
        <td th:text="${user.id}">Id</td>
        <td th:text="${user.firstName}">First name</td>
        <td th:text="${user.lastName}">Last Name</td>
        <td th:text="${user.email}">Email</td>
        <td>
            <form th:action="@{/users/doDelete/}" th:object="${customer}" method="post">
                <button type="submit">Delete</button>
            </form>
        </td>
    </tr>
</table>
</body>
</html>

问题答案：

您不需要表格来执行此操作：

<td>

    <a th:href="@{'/users/doDelete/' + ${user.id}}">

        <span>Delete</span>

    </a>

</td>
