[英]I have problems with bean while creating telegram bot using Spring
我的机器人是关于食谱的。 我有包含字段 id、userName、firstName、lastName 和 registeredAt 的用户实体； 从 CrudRepository 扩展的用户存储库； 机器人配置，其中包含字段 botName、token 和 ownerId； 机器人初始化程序和服务电报机器人。
BotInitializer
@Slf4j
@Component
public class BotInitializer {
@Autowired
TelegramBot tgBot;
@EventListener({ContextRefreshedEvent.class})
public void init() throws TelegramApiException {
TelegramBotsApi telegramBotsApi = new TelegramBotsApi(DefaultBotSession.class);
try{
telegramBotsApi.registerBot(tgBot);
} catch (TelegramApiException e) {
log.error("Error occurred: " + e.getMessage());
}
}
}
