我在使用 Spring 创建电报机器人时遇到 bean 问题

Question

My bot is about recipes. I have user entity with fields id, userName, firstName, lastName, and registeredAt; user repository that extends from CrudRepository; bot config, which contains fields botName, token and ownerId; bot initializer and service telegram bot.

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());
        }
    }
}

service TelegramBot

@Slf4j
@Component
public class TelegramBot extends TelegramLongPollingBot {
    @Autowired
    private UserRepository userRepository;
    final BotConfig botConfig;
    static final String HELP_TEXT = "This bot is created to help find recipes for cooking delicious foods.";

    public TelegramBot(BotConfig botConfig, UserRepository userRepository) {
        this.botConfig = botConfig;
        List<BotCommand> commandList = new ArrayList<>();
        commandList.add(new BotCommand("/start", "start communicating with bot"));
        commandList.add(new BotCommand("/help", "help info"));
        commandList.add(new BotCommand("/category", "category of recipes"));
        commandList.add(new BotCommand("/find", "search recipe by name"));
        commandList.add(new BotCommand("/random", "random recipe"));
        try {
            this.execute(new SetMyCommands(commandList, new BotCommandScopeDefault(), null));
        } catch (TelegramApiException e) {
            log.error("Error setting bots command list: " + e.getMessage());
        }
    }

                    break;
                case "/help" :

        } catch (TelegramApiException e) {

I am trying to connect my bot with mysql database, but i got some errors related to beans and entityManagerFactory.

I'm working on a similar project and had exactly the same issue. Spent plenty of time until figured out that it comes from pom.xml file. I just deleted all versions from the dependencies and reloaded it, seems to me that the problem is that some of the libraries were not loaded properly or the versions were incompatible. Let me know if it works for you.

Here is my example:

 <dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
