@PathVariable和@RequestParam的区别

url:"/t/n/"+weekIndex+"/writeDaily"
@RequestMapping(value = "/n/{weekIndex}/writeDaily", method = RequestMethod.POST)    public String writeDaily(@PathVariable("weekIndex") int weekIndex,            Model model)
@RequestParam 是接收路径中参数
url:"/d/writeDaily?date="+date
@RequestMapping(value = "/writeDaily", method = RequestMethod.POST)    public String writeDaily(@RequestParam("date") String date, Model model)
