SpringMVC中获取request对象

1.注解

@Autowired  

private  HttpServletRequest request;  

 

 2. 在web.xml中配置一个监听

<listener>    

<listener-class>   

 org.springframework.web.context.request.RequestContextListener    

</listener-class>    

</listener>    

之后在程序里可以用

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

 

 3.直接在参数中引用

public String hello(HttpServletRequest request,HttpServletResponse response)
