java - 使用@RequestParam还是@PathVariable？

Question

我正在使用 spring 框架开发一个 REST WebApp，现在我想知道接收数据的最佳实践。最好用 @RequestParam 检索它们或@PathVariable ？显然我有兴趣接收简单的数据，如 userid或username 。使用示例:

@RequestMapping(value = "/getdata", method = RequestMethod.GET)
public String GetData(@RequestParam(value = "memberId", required = true) Integer memberId){
  //return data for user with Id = memberid;
}

或

@RequestMapping(value = "/getdata/{memberid}", method = RequestMethod.GET)
public String GetData(@pathvariable int memberid){
  //return data for user with Id = memberid;
}

我对 REST Web 服务感兴趣

其余约定是使用 uri 变量:
