@PathVariable为空时指定默认值

可以指定多个匹配路径，然后设置参数非必要的，就可以了，例子如下

@RequestMapping(value = {"/timeline/{uid}", "/timeline/{uid}/{size}"})
public ModelAndView getTimeline(@PathVariable(value="uid" ) String articleUserId,
@PathVariable(value="size" , required = false) Integer size,
ModelAndView modelAndView) {
if(size == null) size = 50;
//逻辑
}

对于下面两种URL都是可以处理的
