springMVC 中几种获取request和response的方式

1.最简单方式：参数

@RequestMapping("/test")@ResponseBodypublic void saveTest(HttpServletRequest req, HttpServletResponse resp){　　}

2.加入监听器，然后再controller里面获取

(1)web.xml相应位置插入

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

HttpServletRequest req = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();HttpServletResponse resp = ((ServletWebRequest)RequestContextHolder.getRequestAttributes()).getResponse();
