Python's example code for invoking Java

This article mainly describes the Python call Java instance of the relevant information, the need for friends can refer to the following

Python calls the Java instance in a detailed

Objective:

Python is not as good as Java for server-side programming, so you might want to call Java code

Premise:

Linux Environment

1 Installing Jpype1

Post-Installation test code:

From Jpype import *STARTJVM (Getdefaultjvmpath (), "-ea") java.lang.System.out.println ("Hello World") SHUTDOWNJVM ()

2 calling a non-JDK jar package, Test.jar

The package contains COM. Test class

Package Com;public class Test {public  string test (String str) {    return str;  }}

Python Call Jar Package

Jar_path = Os.path.join (Os.path.abspath ('. '), ' Libs/test.jar ') JPYPE.STARTJVM (Jpype.getdefaultjvmpath (), "-ea", "- djava.class.path=%s "% jar_path) Test = Jpype. Jclass (' com. Test ') # or by Jpackage Reference Test class # com = Jpype. Jpackage (' com ') # Test = com. TESTT = Test () res = T.test ("a") print RESJPYPE.SHUTDOWNJVM ()

Note: Pay attention to permissions issues under Linux
