获取HttpServletRequest几种方法

• 代码获取

先web.xml配置：

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

然后代码获取

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

• spring 直接办法

public ModelAndView userLandlord(Model model, HttpServletRequest request){

}

 

• 注解法

@Autowired
private  HttpServletRequest request;
