I'm newbie in Thymeleaf. I'm trying to create simple crud application. I'm trying to delete object of Customer class on delete button. How can I set parameter(for example - id) to the method which called deleteUser using Thymeleaf. Here's my controller.
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";
}
}
Here's my view.

You do not need form to do this:
<td>
<a th:href="@{'/users/doDelete/' + ${user.id}}">
<span>Delete</span>
</a>
