spring在service层获取session和request

 

 

首先要在web.xml增加如下代码:

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

 

service层调用

@Autowired  
private HttpSession session;  

@Autowired  
private HttpServletRequest request; 

 

普通类中

// 这里整体是一行
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
