Apache flink org.apache.flink.table.sources.CsvBatchTableSourceFactory不支持的属性键：schema.#.proctime

我正在使用Flink 1.12探索

proc time

功能。我有两个测试用例，如下所示。基本上，这两个测试用例做相同的事情，一个是使用

connect和schema definition

，另一个是使用

DDL

第一个（

test1:error one

）失败，第二个

测试（“test2:correct one”）

成功，我想知道第一个失败的原因以及如何使其工作

申请代码：

import org.apache.flink.streaming.api.scala._
import org.apache.flink.table.api.DataTypes
import org.apache.flink.table.api.bridge.scala._
import org.apache.flink.table.descriptors.{Csv, FileSystem, Schema}
import org.apache.flink.types.Row
import org.scalatest.funsuite.AnyFunSuite


class Sql013_ProcessTimeTest2 extends AnyFunSuite {
  test("test 1: error one")  {
    val env = StreamExecutionEnvironment.getExecutionEnvironment
    env.setParallelism(1)
    val tenv = StreamTableEnvironment.create(env)
    val fmt = new Csv().fieldDelimiter(',')
    
    
    val schema = new Schema()
      .field("id", DataTypes.STRING())
      .field("price", DataTypes.INT())
      .field("pt", DataTypes.TIMESTAMP(3)).proctime()  //ERROR here?
    val path = "file:///D:/stock_id_price.csv"
    tenv.connect(new FileSystem().path(path)).withSchema(schema).withFormat(fmt).createTemporaryTable("sourceTable")
    val table = tenv.from("sourceTable")
    table.printSchema()
    table.toAppendStream[Row].print()

    env.execute("Sql013_ProcessTimeTest2")
  }

  test("test 2: correct one")  {
    val env = StreamExecutionEnvironment.getExecutionEnvironment
    env.setParallelism(1)
    val tenv = StreamTableEnvironment.create(env)

        val ddl =
          """
          create table sourceTable(
           id STRING,
           price INT,
           pt as PROCTIME()
          ) with (
             'connector' = 'filesystem',
            'path' = 'D:/stock_id_price.csv',
            'format' = 'csv'
          )


          """.stripMargin(' ')

        tenv.executeSql(ddl)



    val table = tenv.from("sourceTable")
    table.printSchema()
    table.toAppendStream[Row].print()

    env.execute("Sql013_ProcessTimeTest2")
  }

}

在异常消息中查找以下文本（当运行

测试1:error one

）说明原因，但说明第二个测试成功的原因

The matching candidates:
org.apache.flink.table.sources.CsvBatchTableSourceFactory
Unsupported property keys:
schema.#.proctime

运行

测试（“测试1:错误1”）时出现完整错误异常
