java - Thymeleaf:从 Spring-MVC Controller 重定向时，thymeleaf 不反射(reflect)新值

Question

我是 thymeleaf 的新手，thymeleaf 模板引擎非常好，但我面临一些关键问题，这对我来说很难弄清楚。我的流程如下:

首先调用添加用户 Controller 并将新用户添加到数据库中。保存新用户后，重定向到用户列表页面。当用户列表页面打开时，我的新用户不会显示在用户列表中。刷新页面后，我的新用户可见。当我调试代码并检查用户列表 Controller 时。用户列表 Controller 获取新的用户详细信息，但我的 thymeleaf 不显示新的更改。我的 thymeleaf 缓存也是错误的。我正在使用 thymeleaf 布局方言，如下所示:

我的 Controller 代码:

@RequestMapping(value="/add-user", method=RequestMethod.POST)
public String addEditCategory(User user, RedirectAttributes attributes) {

    userService.saveNewUser(user);
    return "redirect:/user/userlist";
}

@RequestMapping(value="/userlist", method=RequestMethod.GET)
public String productCategory(Model model, Pageable pageable) {

    Page<User> page = productCategoryService.findAllUsers(pageable);
    List<User> users= page.getContent();
    PageWrapper<ProductCategory> pageWrapper = new PageWrapper<User>(page, "/user/userlist");

    model.addAttribute("page", pageWrapper);
    model.addAttribute("users", categories);
    return "admin/user/view-users";
}

我的 Thymeleaf 配置:

/* Thymeleaf configuration */
private ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();

    templateResolver.setPrefix("/WEB-INF/views/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCacheable(false);

    return templateResolver;
}

private SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addDialect(new LayoutDialect());
    templateEngine.setTemplateResolver(templateResolver());
    return templateEngine;
}

private ThymeleafViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();

    thymeleafViewResolver.setCharacterEncoding("UTF-8");
    thymeleafViewResolver.setViewClass(ThymeleafView.class);
    thymeleafViewResolver.setViewNames(new String[]{"user/**"});
    thymeleafViewResolver.setTemplateEngine(templateEngine());
    return thymeleafViewResolver;
}

我正在使用 ContentNegotiatingViewResolver 来注册 View 解析器。这个问题就像缓存问题。但我该如何解决这个问题呢？

更新

添加用户:- 单击按钮，将会出现 fancybox。在花式框中，我使用表单并在 /add-user url 上提交表单。

更新

ContentNegotiatingViewResolver 代码:

@Bean
public ViewResolver setupViewResolver(ContentNegotiationManager manager) {
    List<ViewResolver> resolvers = new ArrayList<ViewResolver>();

    resolvers.add(tilesViewResolver());
    resolvers.add(thymeleafViewResolver());
    resolvers.add(jspViewResolver());

    ContentNegotiatingViewResolver viewResolver = new ContentNegotiatingViewResolver();
    viewResolver.setViewResolvers(resolvers);
    viewResolver.setContentNegotiationManager(manager);
    return viewResolver;
}

要禁用缓存，请添加 -

thymeleafViewResolver.setCache(false);
