Jtwig如何获取HttpSession / HttpServletRequest？

Question

Recently began using Jtwig and have no idea how to easily obtain session, servletrequest, remote user and so on. In Thymeleaf, for example, it can be done that way:

<span th:text="${#httpServletRequest.remoteUser}"></span>
...
<p th:text="${#httpSession.getValue(...)}"></p>

Documentation nor Google was not able to answer my question. Probably, this is not implemented (yet?) and i always must put necessary objects manually into the ModelMap?

Answer 1

The request object is added to the model for free. For example, to access the remote user:

{{ request.remoteUser }}

To access a session attribute:

{{ request.session.getAttribute('user') }}

Basically, follow the servlet API starting with the request variable.
