【问题描述】：

我正在使用 Kafka 源 JDBC 连接器来提取数据库事件，并且我正在以独立模式运行 kafka 连接。当我运行这个文件时，我得到了显示的错误。请帮帮我。

代码：

name=sailpointdb01107
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.password = xxxxx
connection.url = jdbc:oracle:thin:@xxxxx:1521/xxxxx
connection.user =xxxxx 
query= SELECT * FROM (SELECT NAME, TO_TIMESTAMP('19700101', 'YYYYMMDD')+ NUMTODSINTERVAL(COMPLETED/1000,'SECOND') AS TASKFAILEDON FROM task WHERE COMPLETION_STATUS='Error')
mode= timestamp
timestamp.column.name=TASKFAILEDON
topic.prefix=testing
validate.non.null=false
transforms=TimestampConverter
transforms.TimestampConverter.type=org.apache.kafka.connect.transforms.TimestampConverter$Value
transforms.TimestampConverter.format=yyyy-MM-dd
transforms.TimestampConverter.target.type=Timestamp
transforms.TimestampConverter.target.field=TASKFAILEDON

错误：

【问题讨论】：

格式化代码和错误块以增强可读性和（可能）影响。还有一些拼写/语法更正。
嗨！你能解决这个问题吗？

【解决方案1】：

在连接器上配置的这条线可以避免这个问题。

time.precision.mode: "连接"
