apache-kafka - Debezium-不包含连接器类型

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。

独立模式的

connector.properites 需要属性文件格式。所以请把 config 部分改写成

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