@RequestParam注解是获取静态URL传入的参数

@PathVariable是获取请求路径中的变量作为参数

@RestController
@RequestMapping(value="users")
public class UserController {
 
    @RequestMapping(value = "/list", method = {RequestMethod.GET, RequestMethod.POST})
    public Map<String, Object> list(@RequestParam Long user_id) {
    		Map<String, Object> map = new HashMap<String, Object>();
    		map.put("user_id", user_id);
        return map;
    }
    @RequestMapping(value = "/get_user/{user_id}", method = {RequestMethod.GET, RequestMethod.POST})
    public Map<String, Object> get_user(@PathVariable Long user_id) {
    		Map<String, Object> map = new HashMap<String, Object>();
    		map.put("user_id", user_id);
        return map;
    }
}
