Python安装jpype调用java，安装jaydebeapi通过jdbc连接数据库

pip install JPype1或下载JPype1-0.7.0.tar.gz包

经常出现需要安装VC++服务等

测试代码如下：

 # Author: zfh
 import jpype,os,time,timer
 from jpype import java
 from jpype import javax

 HOST='192.168.48.103'
 PORT=9999
 USER=''
 PASS=''

 URL = "service:jmx:rmi:///jndi/rmi://%s:%d/jmxrmi" % (HOST, PORT)
 print('URL-->',URL)
 jvmPath = jpype.getDefaultJVMPath()
 print('jvmPath-->',jvmPath)
 #this it the path of your libjvm /usr/lib/jvm/sun-jdk-1.6/jre/lib/amd64/server/libjvm.so on linux
 # jpype.startJVM("C:\Program Files\Java\jre1.8.0_191\bin\server\jvm.dll")
 if not jpype.isJVMStarted():
     jpype.startJVM(jvmPath)
 jpype.java.lang.System.out.println('Hello world!')
 # print(jpype.startJVM("C:\Program Files\Java\jre1.8.0_191\bin\server\jvm.dll"))
 jhash  = java.util.HashMap()
 jarray = jpype.JArray(java.lang.String)([USER,PASS])
 jhash.put(javax.management.remote.JMXConnector.CREDENTIALS, jarray);
 jmxurl = javax.management.remote.JMXServiceURL(URL)
 jmxsoc = javax.management.remote.JMXConnectorFactory.connect(jmxurl,jhash)
 try:
     connection = jmxsoc.getMBeanServerConnection();
 except Exception as e:
     print(e)
 print('connection-->',connection)
 #
 #
 while True:
     time.sleep(60)
     object="java.lang:type=Threading"
     attribute="ThreadCount"
     attr=connection.getAttribute(javax.management.ObjectName(object),attribute)
     print('ThreadCount-->',attribute, attr)
     #
     #Memory is a special case the answer is a Treemap in a CompositeDataSupport
     object="java.lang:type=Memory"
     attribute="HeapMemoryUsage"
     attr=connection.getAttribute(javax.management.ObjectName(object),attribute)
     print('HeapMemoryUsage-->',attr.contents.get("used"))
     #ceshi
     object="kafka.server:type=BrokerTopicMetrics,name=MessagesInPerSec"
     attribute="Count"
     attr=connection.getAttribute(javax.management.ObjectName(object),attribute)
     print('Count-->',attribute,attr)

     object="java.lang:type=OperatingSystem"
     attribute="Version"
     attr=connection.getAttribute(javax.management.ObjectName(object),attribute)
     print('Version-->',attribute,attr)

     object="kafka.server:type=ReplicaManager,name=PartitionCount"
     attribute="Value"
     attr=connection.getAttribute(javax.management.ObjectName(object),attribute)
     print('Value-->',attribute,attr)

运行结果如下：（记录一下jvmPath）

 URL--> service:jmx:rmi:///jndi/rmi://192.168.48.103:9999/jmxrmi
 jvmPath--> C:\Program Files\Java\jre1.8.0_211\bin\server\jvm.dll
 Hello world!
 connection--> javax.management.remote.rmi.RMIConnector$RemoteMBeanServerConnection@531d72ca
 ThreadCount--> ThreadCount 60
 HeapMemoryUsage--> 156563848
 Count--> Count 0
 Version--> Version 2.6.32-431.el6.x86_64
 Value--> Value 24

安装pip install JayDeBeApi 或下载JayDeBeApi-1.1.1.tar.gz(安装JayDeBeApi依赖JPype1)
