Question

我正在尝试使用python代码中的redshift-fake-driver（https://github.com/opt-tech/redshift-fake-driver）连接到Postgres DB。但是我无法加载驱动程序。

我正在基于rappdw / docker-java-python映像在docker容器中运行python代码

import jpype
import os
import inspect
import jaydebeapi

jar = r'/drivers/redshift-fake-driver_2.12-1.0.10.jar'
args='-Djava.class.path=%s' % jar
jvm_path = jpype.getDefaultJVMPath()
jpype.startJVM(jvm_path, '-ea', args)

conn = jaydebeapi.connect('jp.ne.opt.redshiftfake.postgres.FakePostgresqlDriver',"localhost", "airflow","airflow")
curs = conn.cursor()

当前我遇到此异常：

 File "/test.py", line 12, in <module>
    "loclahost", "airflow","airflow")
  File "/usr/local/lib/python3.6/site-packages/jaydebeapi/__init__.py", line 381, in connect
    jconn = _jdbc_connect(jclassname, url, driver_args, jars, libs)
  File "/usr/local/lib/python3.6/site-packages/jaydebeapi/__init__.py", line 190, in _jdbc_connect_jpype
    jpype.JClass(jclassname)
  File "/usr/local/lib/python3.6/site-packages/jpype/_jclass.py", line 73, in JClass
    raise _RUNTIMEEXCEPTION.PYEXC("Class %s not found" % name)
jpype._jexception.RuntimeExceptionPyRaisable: java.lang.RuntimeException: Class jp.ne.opt.redshiftfake.postgres.FakePostgresqlDriver not found

将redshift-fake-driver导入python时找不到类
