SpringMVC中获取request对象

一、注解，自动装载

@Autowired
private  HttpServletRequest request;

 

二、web.xml中配置一个监听

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

之后可以

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

 

三、参数中直接引入

public String hello(HttpServletRequest request,HttpServletResponse response)
