Spring在service层获取session和request

获取request有两种方法：

• 1.在web.xml文件中添加监听器,然后通过注解注入request：

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

  然后在service层注入直接注入对象

  @Autowired  
  private HttpSession session;  
  
  @Autowired  
  private HttpServletRequest request; 

   

• 2.直接在service层普通类中获取

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