Question

我正在尝试使用Jconn4和jaydebeapi软件包连接到IBM OMNIBUS对象服务器数据库，但是我一直在获得

jpype._jexception.RuntimeExceptionPyRaisable：java.lang.RuntimeException：找不到com.sybase.jdbc4.jdbc.SybDriver类

我尝试将jconn4.jar移至Java的安装位置并更改代码中的路径

import jaydebeapi
import os
import jpype                                                                                                                                                                                                                     
conn = jaydebeapi.connect('com.sybase.jdbc4.jdbc.SybDriver', ['jdbc:sybase:Tds:ip:4100/alerts','user','pass'],['/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/lib/jconn4.jar'])
curs = conn.cursor()

我的输出看起来像

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    conn = jaydebeapi.connect('com.sybase.jdbc4.jdbc.SybDriver', ['jdbc:sybase:Tds:ip:4100/alerts','user','pass'],['/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/lib/jconn4.jar'])

    jpype.JClass(jclassname)

    raise _RUNTIMEEXCEPTION.PYEXC("Class %s not found" % name)
jpype._jexception.RuntimeExceptionPyRaisable: java.lang.RuntimeException: Class com.sybase.jdbc4.jdbc.SybDriver not found

Answer 1

我相信connect函数的参数是：类名，URL，args，jar路径。

您可以尝试：

conn = jaydebeapi.connect('com.sybase.jdbc4.jdbc.SybDriver', 'jdbc:sybase:Tds:ip:4100/alerts', {'user': 'user', 'password': 'pass'}, '/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/lib/jconn4.jar')

找不到Python jaydebeapi类com.sybase.jdbc4.jdbc.SybDriver
