java - Apache NiFi 无法使用 ojdbc6.jar 或 ojdbc8.jar 连接到 Oracle 12c

Question

我们正在尝试从 Apache NiFi 连接到 Oracle 12c 数据库。但它根本不起作用:我们收到以下错误:

bdc2314a-669e-1e85-875c-73b035db9ba5
ExecuteSQL[id=bdc2314a-669e-1e85-875c-73b035db9ba5] Unable to execute SQL select query select * from ETSETTRA.APB where rownum < 10 due to java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for connect URL 'jdbc:oracle:thin@//osiXXXX:1521/UTSOFTP'. No FlowFile to route to failure: org.apache.nifi.processor.exception.ProcessException: java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for connect URL 'jdbc:oracle:thin@//osiXXXX:1521/UTSOFTP

配置如下。我尝试了很多其他组合

这应该是直接的吗？

Answer 1

我认为驱动程序名称不正确:

oracle.jdbc.driver.OracleDriver

对比

oracle.jdbc.OracleDriver

Difference between Oracle jdbc driver classes?
