Springboot/Thymeleaf 从每个页面的模型中检查当前用户

Mar*_*lic 2 html java spring thymeleaf spring-boot

我试图为每个页面提供以下模型,以便我可以检查当前用户是否已登录,从而控制每个页面的标题菜单项,但我不想总是返回 index.html 。有什么办法可以返回自己吗?

@RequestMapping(value = "/**", method = RequestMethod.GET)
String index(Model model) {
 Users user = usersRepository.findOne(1 L);

 if (user != null) {
  String currentRole = user.getRole().toString();
  model.addAttribute("currentRole", currentRole);
  // System.out.println("Current Role: " + currentRole);
 } else {
  model.addAttribute("currentRole", "ANONYMOUS");
 }

 return "index";
}

我的菜单:

<li th:switch="${currentRole}">
   <!-- Is Employee, so show "My Requests" -->
   <div th:case="EMPLOYEE">
      <a href="#" th:href="@{/requests}">
         <div style="float: left; margin-right: 10px;">My Requests</div>
         <!-- Handle notifications here -->
         <div style="overflow: hidden" id="circle">1</div>
      </a>
   </div>
   <!-- Is Manager, so show "My Approvals" -->
   <div th:case="MANAGER">
      <a href="#" th:href="@{/requests}">
         <div style="float: left; margin-right: 10px;">My Approvals</div>
         <!-- Handle notifications here -->
         <div style="overflow: hidden" id="circle">1</div>
      </a>
   </div>
</li>
<li><a href="#" th:href="@{/team}">My Team</a></li>
<!-- Is logged in, so don't show "Log In" -->
<li th:unless="${currentRole}">
   <a href="/login" th:href="@{/login}" class="btn-login">Log In</a>
</li>
</ul>

如果您使用的是 Spring 安全性,Thymeleaf 有一个集成模块可以直接在您的模板中处理此问题,因此您可能甚至不需要模型中的用户名。将依赖项添加到相应版本的org.thymeleaf.extras:thymeleaf-extras-springsecurity4.

然后将 xmlns 添加到您的 html

<html xmlns:th="http://www.thymeleaf.org"
            xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

你可以做

<div th:text="${#authentication.name}">
    The value of the "name" property of the authentication object should appear here.
</div>
