Thymeleaf中获取作用域中的数据

Thymeleaf中去的作用域中数据的方法和jsp相似，熟悉jsp的开发者很容易学会

先看一个demo，Model，request,session,ServletContext中的数据

public String One(Model model, HttpServletRequest request, HttpSession session){
        Person p1=queryPerson.query(1001);
        model.addAttribute("Tom",p1);
        model.addAttribute("req","hello");
        request.setAttribute("req","Hello");
        session.setAttribute("ses","Http!");
        request.getServletContext().setAttribute("app","App");

        return "Tom";
    }

model中的数据实际上就是request中的数据，以下写法都可以拿到数据

<h1 th:utext="${Tom.gender}">Hello</h1>
<h1 th:utext="${req}">Hello</h1>

<h1 th:utext="${#request.getAttribute('req')}"></h1>
<h1 th:utext="${#httpServletRequest.getAttribute('req')}"></h1>


<!--无法得到<h1 th:utext="${session.getAttribute('ses')}"></h1>-->
<h1 th:utext="${session.ses}"></h1>
<h1 th:text="${#request.getSession().getAttribute('ses')}"></h1>
<h1 th:text="${#session.getAttribute('ses')}"></h1>
<h1 th:text="${#httpSession.getAttribute('ses')}"></h1>


<h1 th:utext="${#request.getServletContext().getAttribute('app')}"></h1>
<h1 th:utext="${#servletContext.getAttribute('app')}"></h1>

基本可以看出写法很多，不唯一，有任意的写法都可以

httpServletRequest

<h1 th:utext="${#httpServletRequest.getAttribute('req')}"></h1>

httpSession

<h1 th:text="${#httpSession.getAttribute('ses')}"></h1>

servletContext

<h1 th:utext="${#servletContext.getAttribute('app')}"></h1>
