Pyjnius是一个用于访问Java类的Python库。
适用场景：极个别的加密算法等内容，用python不方便实现或者实现较耗时，可基于Pyjnius把java类当做python库使用。
文档：http://pyjnius.readthedocs.io/en/latest/installation.html
下载地址：https://pypi.python.org/pypi?%3Aaction=search&term=jnius&submit=search
注意jnius的版本管理有点混乱，目前看来选择jniusx比较好。
先安装Java JDK 和JRE、Cython
# pip3 install cython # pip3 install jniusx Collecting jniusx Downloading jniusx-1.0.5.tar.gz Requirement already satisfied: six>=1.7.0 in /opt/python3.5/lib/python3.5/site-packages (from jniusx) Requirement already satisfied: cython in /opt/python3.5/lib/python3.5/site-packages (from jniusx) Installing collected packages: jniusx Running setup.py install for jniusx ... done Successfully installed jniusx-1.0.5
注意：jnius安装的坑比较多，请参考http://stackoverflow.com/search?q=jnius
如果出现ImportError，一般是java环境变量或者path没有配置好。
jnius/jnius.c:4:20: fatal error: Python.h 一般为缺python-dev, yum -y install python-devel
pip 安装不成功可以尝试 setup.py方式。
jnius/jnius.c: No such file or directory 需要利用原来保存的clone。
hello world 实例：
#!/usr/bin/env python # -*- coding: utf-8 -*- # jnius_quick2.py # Author Rongzhong Xu 2016-08-02 wechat: pythontesting # https://bitbucket.org/china-testing/python-chinese-library/src """ jnius demo Tested in python2.7 """ from jnius import autoclass System = autoclass(‘java.lang.System‘) System.out.println(‘Hello World‘)
堆栈实例：
#!/usr/bin/env python # -*- coding: utf-8 -*- # jnius_quick1.py # Author Rongzhong Xu 2016-08-02 wechat: pythontesting # https://bitbucket.org/china-testing/python-chinese-library/src """ jnius demo Tested in python2.7 """ from jnius import autoclass Stack = autoclass(‘java.util.Stack‘) stack = Stack() stack.push(‘hello‘) stack.push(‘world‘) print(stack.pop()) # --> ‘world‘ print(stack.pop()) # --> ‘hello‘
调用java String的hashCode

测试：

IPython 5.1.0 -- An enhanced Interactive Python. ? -> Introduction and overview of IPython‘s features. %quickref -> Quick reference. help -> Python‘s own help system. object? -> Details about ‘object‘, use ‘object??‘ for extra details. In [2]: # 注意要先把jar加载CLASSPATH环境变量。 In [3]: from jnius import autoclass In [4]: Bla = autoclass(‘com.sample.Beach‘) In [5]: s = Bla("Tom", "Shenzhen") In [6]: s.getName() Out[6]: ‘Tom‘ ``` 封装某模块的加密机制为python包实例： * 拷贝： com cn org 到新建的临时目录 * echo Main-Class: AESUtil >manifest.txt * jar cvfm Test.jar manifest.txt * 测试代码： ```python # -*- coding: utf-8 -*- # 注意要先把jar加载CLASSPATH环境变量。 from jnius import autoclass AESUtil = autoclass(‘com.oppo.sso.util.AESUtil‘) email = AESUtil.aesEncrypt("hello@126.com","我是一个加密密钥") print(email)
注意：以上打包方式和具体环境很相关，建议尽量本机打包，本机执行。
