安装
先安装Java JDK 和JRE、Cython
# pip3 install cython# pip3 install jniusxCollecting 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。

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)
