【问题描述】：

我正在尝试将 MySql 源连接器与 debezium 支持的发件箱 SMT 一起使用，并具有以下配置。我正在使用最新的 debezium-core 和 debezium-mysql-connector (1.1) jars

curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" localhost: 8083/connectors/ -d '{
    "name": "debezium-mysql-connector",
    "config": {
        "connector.class": "io.debezium.connector.mysql.MySqlConnector",
        "tasks.max": "1",
        "database.hostname": "MySql",
        "database.port": "3306",
        "database.user": "**",
        "database.password": "**",
        "database.server.id": "1033113244",
        "database.server.name": "anomaly-changelog",
        "database.whitelist": "anomaly",
        "database.history.kafka.bootstrap.servers": "Kafka:9092",
        "database.history.kafka.topic": "anomaly.schema.history",
        "transforms": "outbox,reroute",
        "transforms.reroute.type": "org.apache.kafka.connect.transforms.RegexRouter",
        "transforms.reroute.regex": "(.*)",
        "transforms.reroute.replacement": "$1-SMT",
        "transforms.outbox.type": "io.debezium.transforms.outbox.EventRouter"
    }
}'

但我仍然收到以下错误：

{"error_code":400,"message":"Connector configuration is invalid and contains the following 2 error(s):\nInvalid value io.debezium.transforms.outbox.EventRouter for configuration transforms.outbox.type: Class io.debezium.transforms.outbox.EventRouter could not be found.\nInvalid value null for configuration transforms.outbox.type: Not a Transformation}

我不明白为什么它没有被识别。

【问题讨论】：

好像没有正确安装。您如何安装 Debezium 连接器？ Confluent Hub 还是其他方式？
嗨 Robin，我已经下载了 jar 文件并将它们复制到远程机器中

【解决方案1】：

你可以试试这样的：

curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" demo:8083/connectors/ -d '{ "name": "order-connector", "config": { "connector.class": "io.debezium.connector.mysql.MySqlConnector", "tasks.max": "1", "database.hostname": "mariadb_order", "database.port": "3306", "database.user": "root", "database.password": "***", "database.server.id": "223344", "database.server.name": "orderdbserver","table.whitelist": "orderdb.outbox", "transforms": "outbox", "transforms.outbox.type" :"io.debezium.transforms.outbox.EventRouter", "database.history.kafka.bootstrap.servers": "kafka:9092", "database.history.kafka.topic":"dbhistory.orderdb", "transforms.outbox.table.fields.additional.placement" : "aggregateid:envelope:id"  } }'
