Debezium-不含连接器类型

Question

我正在尝试使用 Debezium 连接到本地计算机上的 mysql 数据库。

尝试使用以下命令调用kafka： sudo kafka/bin/connect-standalone.shsh kafka/config/connect-standalone.properties kafka/config/connector.properties

这是connector.properties中的配置：

{
  "name": "inventory-connector",
  "config": {
    "connector.class": "io.debezium.connector.mysql.MySqlConnector",
    "database.hostname": "127.0.0.1",
    "tasks.max": "1",
    "database.port": "3306",
    "database.user": "debezium",
    "database.password": "Password@123",
    "database.server.id": "1",
    "database.server.name": "fullfillment",
    "database.whitelist": "inventory",
    "database.history.kafka.bootstrap.servers": "localhost:9092",
    "database.history.kafka.topic": "dbhistory.fullfillment",
    "include.schema.changes": "true",
    "type": "null"
  }
}

运行上述命令时出现以下错误：

[2018-12-07 10:58:17,102] ERROR Stopping after connector error (org.apache.kafka.connect.cli.ConnectStandalone:113)
java.util.concurrent.ExecutionException: org.apache.kafka.connect.runtime.rest.errors.BadRequestException: Connector config {"config"={, "type"="null", "database.user"="debezium",, "database.port"="3306",, "include.schema.changes"="true",, "database.server.name"="fullfillment",, "connector.class"="io.debezium.connector.mysql.MySqlConnector",, "tasks.max"="1",, "database.history.kafka.topic"="dbhistory.fullfillment",, "database.server.id"="1",, "database.whitelist"="inventory",, "name"="inventory-connector",, "database.hostname"="127.0.0.1",, {=, "database.password"="Password@123",, }=, "database.history.kafka.bootstrap.servers"="localhost:9092",} contains no connector type

任何帮助将不胜感激。

Answer 1

您有一个 JSON 文件，而不是属性文件。

这意味着与connect-distributed模式一起使用。并通过 HTTP 发布到 Kafka Connect REST API，而不是作为 CLI 参数。

对于，您可以同时connect-standalone提供 Connect工作线程属性和连接器.properties属性文件（作为 Java文件）。

Answer 2

connector.properites对于独立模式需要属性文件格式。所以请采取config部分并重写它像

connector.class=io.debezium.connector.mysql.MySqlConnector
