获取 HttpServletRequest 三种方法

一、注解法

@Autowired
private  HttpServletRequest request;

二、在方法中直接声明形参有HttpRequest即可

public ModelAndView userLandlord(Model model, HttpServletRequest request){
 
}

三、使用一个Listener，然后获取

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();
