@RequestMapping("/Menubar")
public String Ajax(Model model, HttpServletRequest req) {
    List l2 = new ArrayList();

    List l = menuService.listMenus();
    Iterator i = l.iterator();
    while (i.hasNext()) {
        String s = (String) i.next();
        System.out.println(s);

        List submenu = menuService.getSubMenu(s);

        System.out.println(submenu
                + "sub menuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu");

        menu m = new menu();
        m.setS(s);
        m.setL(submenu);
        l2.add(m);

    }
    HttpSession hs = req.getSession();
    hs.setAttribute("lokesh", l2);


    System.out.println(l2);
    return "Menubar";

}

@RequestMapping("/test")
public String hom(Model model, HttpServletRequest req) {


    return "test";

}

th:include will pull and render whatever the th:fragment encompases.

th:include将拉动并渲染th:fragment包含的内容。

e.g.

    <div th:fragment="show_data">
<p>Hello Data<p>
<p><span th:text="${somedata}></span></p>
    </div>

the render will result in following being passed to the controller method:

渲染将导致以下传递给控制器​​方法:

<p>Hello Data<p>
<p><span th:text="${somedata}></span></p>

If the th:fragment contains variables e.g. ${somedata} which you want rendered on your main page, you must remember to pass that same variable to your main page otherwise it won't get rendered.

如果th:片段包含变量,例如要在主页上呈现的$ {somedata},您必须记住将相同的变量传递给主页,否则将无法呈现。

e.g.

public String main(Model model) {
model.addAttribute("somedata", "this is test data.");
return "main";
}

will result in render of:

将导致渲染:

// main page content
This is main page data.
// fragment content
Hello Data
this is test data
//continuation of main page content
blah blah blah
