RestTemplate不可以把对象解析为查询参数吗?

如何将对象的列表作为QueryParameter发送?是否可以将对象作为QueryParameter发送?

User u1=new User();
User u2=new User();

List<User> user=new ArrayList<>();
user.add(u1);
user.add(u2);

// How to send the above List of Objects as QueryParameter ???

HttpEntity<Object> entity=new HttpEntity<>(user,headers);

ResponseEntity<boolean> response= restTemplate.postForEntity(url,entity,User.class);

另外,如何接收对象列表的响应?

boolean getResponse( @RequestParam List<User> user ){  // This way is not possible.
}
