如何在jdbc-sink-connector模式信息中指定数据类型“日期”？

Question

• 我是kafka-connect的新手
• 我想使用oracle-jdbc-sink-connector将数据从kafka主题写入oracle
• 我目前无法使用avro / schema-registry，因此它必须是数据集中包含模式信息的JSON
• 具有简单数据类型（如int，string）的“ hello world”数据集已成功写入通过连接器自动创建功能创建的oracle表

现在我被困住了，因为我想在我的有效载荷中使用“日期”数据类型，但我不知道如何在模式信息中指定它。

这是错误消息（connect-distributed.log）

        ... 13 more

这是我的JSON的相关部分：

{"records":
    [{"value":  
        {"schema": 
            { "type": "struct", "fields": 
                [{"type": "org.apache.kafka.connect.data.Date", "optional": false, "field": "BEZDAT"}
                ...]
                , "optional": false, "name": "foobar"}
        , "payload": {"BEZDAT": "2020-07-15"
        ...}}]}'

我还尝试将Date，'Date'，“ Date”，Date用作 type

根据documentation，可以使用“日期”。但是如何指定？我想念什么吗？
