Spring在service層獲取session和request

獲取request有兩種方法：

• 1.在web.xml文件中添加監聽器,而後經過註解注入request：

  <listener>    
      <listener-class> org.springframework.web.context.request.RequestContextListener </listener-class> </listener>

  @Autowired private HttpServletRequest request; 

• 2.直接在service層普通類中獲取

  HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();

  獲取session的方法以下：

• 在service層注入HttpSession對象，而後直接獲取

  @Autowired private HttpSession session; public void getsession (){ String name = (String) session.getAttribute("name"); }
