Python调用jar包

import jpype
from jpype import *
import numpy as np
b= np.array([1,2,3,4,5])
jar_path='/home/chk/PycharmProjects/pythonProject/poi-5.0.0.jar'
jvmPath = jpype.getDefaultJVMPath()
jpype.startJVM(jvmPath,"-ea","-Djava.class.path=%s" %jar_path) #如果这里是有自定义jar,就把jar地址填入
java.lang.System.out.println("Hello World")
Test = jpype.JClass('org.apache.poi.POIXMLDocument') #取得包中的类
a=Test()# 尝试调用类的一个方法
print(a)
# jpype.java.lang.System.out.println( " hello world! " )
jpype.shutdownJVM()
