你可以通过获取所在频道的历史记录并根据消息的ID从历史记录中获取消息的“Message”对象。
“Message”对象有一个“getReactions”方法，它返回消息上所有反应的列表，然后你可以遍历这些反应，然后再遍历给定反应上的所有用户，并将每个反应的用户名/ID保存到你选择的数组、列表或数据结构中。
英文:
You can get the Message object of the message by getting the history of the channel its in and then get the message by id from the history.
The Message object has a getReactions method that returns a list of all reactions on a message, you can then iterate through the reactions and in turn then iterate thru all the users that reacted on the given reaction and save the name/id of each user who reacted into an array or list or data structure of your choice.

List<MessageReaction> reactionsList = event.event.getMessage().getReactions();
// List of users that reacted to every possible emote.
for (int i = 0; i < reactionsList.size(); i++)
{
List<User> users = reactionsList.get(i).retrieveUsers().complete();
}
英文:
List<MessageReaction> reactionsList = event.event.getMessage().getReactions();
// List of users that reacted to every possible emote.
for (int i = 0; i < reactionsList.size(); i++)
{
List<User> users = reactionsList.get(i).retrieveUsers().complete();
}
