2.java项目打包

3.python程序调用

# -*-coding:utf-8-*-

import jpype

from jpypeimport *

# 获得默认jvm路径，即jvm.dll文件路径

jvmPath = jpype.getDefaultJVMPath()

print(jvmPath)

# java扩展包路径

ext_classpath =r'F:\Jpython\target\Jpython-1.0-SNAPSHOT.jar'

jvmArg ='-Djava.class.path=%s' % ext_classpath

print(jvmArg)

if not jpype.isJVMStarted():

# 启动Java虚拟机

    jpype.startJVM(jvmPath, '-ea', jvmArg)

jpype.java.lang.System.out.println('Hello world!')

# 获取相应的Java类

javaClass = JClass("com.Javatest")

jd = javaClass()

jprint = java.lang.System.out.println

jprint(jd.run("waw"))

a = jd.testParam("test")

print(a)

shutdownJVM()

执行结果如下
