问题描述
我正在尝试从python中打开一个JAR文件并遇到问题。我正在使用..
import os
os.system(rX:\ file.jar)
它似乎打开窗口然后立即关闭,我知道我错过了一个简单的命令但是不知道它是什么,谢谢你的帮助
你想从.jar执行代码,还是打开它? / p>
如果打开,那么 .jar
文件的格式与 .zip $相同c $ c>文件,您可以使用
zipfile
模块来操作它。示例:
def show_jar_classes(jar_file):
打印出来自jar_file的.class文件
zf = zipfile.ZipFile(jar_file,'r')
try:
lst = zf.infolist()
for zi in lst:
fn = zi.filename
if fn.endswith('。class'):
print(fn)
finally:
zf.close()
如果你想执行它,那么我更喜欢创建一个简单的批处理/ shell脚本,它执行 java
参数如 -Xmx
以及应用程序所需的环境设置。
I am trying to open a JAR file from python and running into problems. I am using..
import os
os.system(r"X:\file.jar")
it appears to open the window then it shuts right away, I know I am missing a simple command but not sure what it is, thanks for the help
Do you want to execute code from .jar, or open it?
If open, then .jar
file is the same format as .zip
files and you can use zipfile
module to manipulate it. Example:
def show_jar_classes(jar_file):
"""prints out .class files from jar_file"""
zf = zipfile.ZipFile(jar_file, 'r')
try:
lst = zf.infolist()
for zi in lst:
fn = zi.filename
if fn.endswith('.class'):
print(fn)
finally:
zf.close()
If you want to execute it then I prefer creating simple batch/shell script which execute java
with some parameters like -Xmx
and with environment settings required by application.
