Method from controller

  @RequestMapping("/custom/{pageName}") public String getCustomPage(@PathVariable String pageName, Model model) { GlPage p = pageService.findByUrl(pageName); if(!p.isPublished()) { return "pagemanager"; } else { ArrayList<GlPage> allPages = (ArrayList<GlPage>)pageService.getAllPages(); model.addAttribute("pages", allPages); return "template"; } }
  • It is not clear what you want to get. Starting with what is considered a title — a <title> tag, an <h1> or something else? And how should it change, what should be substituted there and by what condition? - Slava Semushin
  • The <h1> tag is a header. There is a class GlPage, which has attributes id, title, url, published. This piece of code forms a menu with links to all available pages. <ul class = "nav navbar-nav"> <li th: each = "page: $ {pages}"> <a th: text = "$ {page.title}" th: href = "$ {page.url } "> 123 </a> </ li> </ ul> Suppose I follow the first link, where url = star_wars, and title = Star Wars. So how can I substitute this very title in h1? - Blackjack

Suppose I follow the first link, where url = star_wars, and title = Star Wars. So how can I substitute this very title in h1?

In the controller, you have this same page, right? Throw it in the view and display it there.

Example:

 GlPage p = pageService.findByUrl(pageName); model.addAttribute("page", p);

and

 <h1 th:text="${page.title}">Оглавление</h1>
  • I have an array of all the pages there, which I pass to the view and is there any way to get the title of the current page that I have switched to? - Blackjack

Problem solved. I decided this: in the controller I created the variable GlPage currentPage = pageService.findByUrl(url) , and then added it to the model model.addAttribute("currentPage", currentPage) and called it in the <h1 th:text="${currentPage.title}"></h1> . Thanks @SlavaSemushin , pushed on this idea.

  • For "thank you" there is a special button here;) - Slava Semushin
