springmvc传参问题

@RequestMapping(value = "/addHit", method = { RequestMethod.POST,
			RequestMethod.GET })
	public @ResponseBody
	@Transactional  //传入参数不为八大基本类型，可传可不传，否则必传；
	Object addHit(HttpServletRequest request, String userId, String mediaType,
			String playsId, Double playPercent, Integer playDuration, double number,int type) {//number,type 必传
}

　　

@RequestMapping(value = "/addHit", method = { RequestMethod.POST,
			RequestMethod.GET })
	public @ResponseBody
	@Transactional  /
	Object addHit(HttpServletRequest request, 
@RequestParam(value="userId",required=true,defaultValue="0") String userId,//必传参数

@RequestParam(value="videoId",required=false,defaultValue="0") String videoId,//非必传参数
String playsId, Double playPercent, Integer playDuration) {//非必传参数
}
