卡夫卡消息未插入数据库

问题描述

Kafka消息未插入到postgresql数据库中。我可以在使用者中看到消息，但消息未插入表中。任何建议都会有所帮助。

Sink_connect.properties

connection.url=jdbc:postgresql://localhost:5432/postgres
user=postgres
password=xxxxxx
insert.mode=insert
table.name.format=kafka_sink_pg
pk.mode=none
pk.fields=none
auto.create=true

制作人

kafka-avro-console-producer  --broker-list localhost:9092 --topic Kafka_pg  --property value.schema='{"type":"record","name":"kafka_sink_pg","fields":[{"name":"serial_no","type":"int"},{"name":"technology","type": "string"},{"name":"platform","type": "string"}]}'

消息

 {"serial_no": 1,"technology": "ETL","platform": "Informatica"}
 {"serial_no": 2,"platform": "Talend"}

下面是日志文件中的错误消息，

[2020-08-12 03:50:09,940] INFO Kafka Connect started (org.apache.kafka.connect.runtime.Connect:57)
[2020-08-12 03:50:09,943] ERROR Failed to create job for ../config/sink-quickstart-Postgres.properties (org.apache.kafka.connect.cli.ConnectStandalone:110)
[2020-08-12 03:50:09,952] ERROR Stopping after connector error (org.apache.kafka.connect.cli.ConnectStandalone:121)
java.util.concurrent.ExecutionException: org.apache.kafka.connect.errors.ConnectException: Failed to find any class that implements Connector and which name matches io.confluent.connect.jdbc.JdbcSinkConnector

解决方法

错误是由于jdbc驱动程序导致插件路径无法标识位置。 通过在connect-avro-standalone.properties文件中提供插件的完整路径来解决此问题

初始

plugin.path=share/java

更改为

plugin.path=/usr/kafka/share/java  #Provided the complete path
