简介
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。

安装
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/python 3.5 / lib / python3.5 / site - packages( from jniusx) Requirement already satisfied: cython in /opt/python 3.5 / 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"htmlcode">

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

jnius demo: Call java String 's hashCode
Tested in python2.7

from jnius
import autoclass
String = autoclass('java.lang.String')
print(String("hello").hashCode())
调用jar包
#!python
#
vi com / sample / Beach.java
package com.sample;
public class Beach {
private String name;
private String city;
public Beach(String name, String city) {
this.name = name;
this.city = city;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
}
#
echo Main - Class: Beach > manifest.txt
# jar cvfm Test.jar manifest.txt com /
sample /*.class*/
