将对象列表解析为百日咳模板，并返回一个Object

标签： spring spring-mvc spring-boot thymeleaf

我在模型中添加了一个属性并返回页面。在admin.html页面中，我遍历所有用户并显示详细信息。但我想将一个用户从列表中返回"/admin/showReports"。

我希望有人可以帮助我。我真的被困了。

控制器

@RequestMapping(value = "/admin")
public String showAllUser(Model model) {
    model.addAttribute("allUser",userDelegate.getAllUser());
    return "admin";
}

@RequestMapping(value = "/admin/showReports", method = RequestMethod.POST)
public String showAllAvailableReportsForUser(Model model, User user) {
    model.addAttribute("user", user);
    model.addAttribute("reports", userDelegate.getAllReports());
    return "addReports";
}

admin.html

<!DOCTYPE html>

                    <th>E-mail</th>

                            <button type="submit">edit</button>
                        </td>
                    </form>
                </tr>
            </table>
        </div>

ThymeleafConfig

@Bean
public SpringResourceTemplateResolver templateResolver(){
    SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
    resolver.setPrefix("classpath:/templates/");
    resolver.setSuffix(".html");
    resolver.setTemplateMode("HTML5");
    resolver.setOrder(1);
    return resolver;

    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver());
    engine.addDialect(new LayoutDialect());
    return engine;

    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    return resolver;
}

您可以通过网址传递唯一标识符来解决问题。

通过id的示例，请注意对GET的更改，因此只需放置一个链接而不是表单。

@RequestMapping(value = "/admin/showReports/{id}", method = RequestMethod.GET)
public String showAllAvailableReportsForUser(Model model, @PathVariable("id") Long id) {
    User user = userDelegate.getUserById(id); // Get user via id
    mav.addObject("user", user);
    // Get and add whatever else you need
    return "addReports";
}
