Spring-integration-kafka - 我正在创建Spring-integration-kakfa应用程序，但在启动时它给了我错误，请在下面找到错误堆栈 -

我可以找到几个基于Java的配置示例，但需要基于XML的Kafka生产者和消费者配置。有人可以帮我这个吗？

kafka-inbound-channel.xml -

其他配置是在调度程序servlet中将普通的Spring MVC应用程序配置导入资源为“kafka-inbound-channle.xml”但在import语句之后它会出现此错误

Answer 1

确实应该显示您的XML配置。否则，喝咖啡真的很难帮助。

您可以在项目的测试中找到一些示例：https://github.com/spring-projects/spring-integration-kafka/tree/master/src/test/java/org/springframework/integration/kafka/config/xml

另一方面，有时这是IDE中的错误。考虑使用符合Spring的版本。例如IntelliJ IDEA或STS。
