flink 在使用upsert_kafka connector 时报错，找不到类Exeption: Could not find any factory for identifier 'upsert-kafka' that implements 'org.apache.flink.table.factories.DynamicTableFactory' in the classpath.

 

 

 原因：因为Flink 加载 table Factory 使用的时SPI机制，而正常的flink jar包是不包含META-INF.services 路径的，需要自己去添加

方法二 maven 添加插件（推荐）

<build>
        <plugins>
