如何让spring存储库使用html表单而不是json进行响应？

public interface UserRepository extends CrudRepository<User, Long> {
}

@Controller
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserRepository userRepository;

    @GetMapping("/form")
    public String showForm(Model model) {
        model.addAttribute("user", new User());
        return "user-form";
    }

    @PostMapping("/save")
    public String saveUser(@ModelAttribute User user) {
        userRepository.save(user);
        return "redirect:/users/form";
    }
}

<form th:object="${user}" th:action="@{/users/save}" method="post">
    <input type="text" th:field="*{name}" placeholder="Name" />
    <input type="email" th:field="*{email}" placeholder="Email" />
    <button type="submit">Save</button>
</form>

spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.html
spring.resources.static-locations=classpath:/static/

@Configuration
public class MvcConfig implements WebMvcConfigurer {
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp("/WEB-INF/views/", ".html");
    }
}
