Could not find any factory for identifier 'kafka' that implements 'org.apache.flink.table.factories.DynamicTableFactory' in the classpath

java配置flinksql表连接kafka。

例如：

tableEnv.executeSql("CREATE TABLE invalidCtp (\n" +
" sys_name STRING,\n" +
" broker_id STRING,\n" +
" investor_id STRING\n," +
" row_rank BIGINT" +
") WITH (\n" +
" 'connector' = 'kafka',\n" +
" 'topic' = 'invalidCtpDetail',\n" +
" 'properties.bootstrap.servers' = '47.104.234.54:9092',\n" +
// " 'connector.startup-mode' = 'latest-offset',\n" +
" 'scan.startup.mode' = 'earliest-offset',\n" +
// " 'kafka.auto.offset.reset' = 'latest',\n" +
" 'format' = 'json'\n" +
")");
本地可运行，服务器报错：Flink 1.12 Could not find any factory for identifier 'kafka' that implements 'org.apache.flink.table.factories.DynamicTableFactory' in the classpath

解决办法：

pom.xml文件中加入依赖（也可去如下网站下载对应版本）

https://mvnrepository.com/artifact/org.apache.flink/flink-sql-connector-kafka_2.11/1.12.1

<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-sql-connector-kafka_${scala.binary.version}</artifactId>
<version>${flink.version}</version>
<!--<scope>provided</scope>-->
</dependency>
然后把该依赖包（flink-sql-connector-kafka_${scala.binary.version}）放到flink安装目录的lib目录下：

 

加入该依赖包后，可能会导致如下报错：flink提交任务报错：java.lang.ClassCastException LinkedMap cannot be cast to LinkedMap exceptions

解决办法：

在conf/flink-conf.yaml添加如下内容并重启flink：

classloader.resolve-order: parent-first
