如何配置我想使用的模块：kafka、eureka-server 和 telegram-bot

问题描述 投票：0回答：1

嗯，我想创建一个模块，在其中接收用户订阅的电报通知，给他的消息必须发送 kafka 监听器，然后用户必须在电报的机器人中收到通知，但我有一个问题，机器人的依赖项没有配置eureka 服务器或 spring 根本...

我在主 Maven 项目中有这些依赖项：

当我运行具有此依赖项的应用程序时，我得到：

如果我将这些依赖项添加到电报模块中：

   <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.4.0-b180830.0359</version>
        </dependency>

我得到了：

所以，我不明白该怎么做，以及如何修复它，因为我需要 eureka 服务器和 telegram bot api，如果我删除 telegram 依赖项，应用程序就会正常启动。

java spring-boot maven telegram-bot netflix-eureka

好吧，问题是 telegram api 也使用 spring api，所以你需要去这里检查你的 spring 版本是否与使用的 telegram api 相同。
