[英]Location of python source code in Jython/Java integration
I could integrate the java/jython from this source . 我可以从这个源集成java / jython。
I downloaded the jython
with brew
, so the jar file is located in /usr/local/Cellar/jython
directory. 我用
brew
下载了jython
,因此jar文件位于/usr/local/Cellar/jython
目录中。
I came up with the following script to build the class file into the _build directory, but the issue is that I had to copy the python (jython) source into the directory also to make the integration work. 我想出了以下脚本来将类文件构建到_build目录中,但问题是我必须将python(jython)源复制到目录中以使集成工作。
#!/bin/bash
DIRECTORY="_build"
if [ ! -d "$DIRECTORY" ]; then
# Control will enter here if $DIRECTORY exists.
mkdir $DIRECTORY
fi
cp Building.py $DIRECTORY
javac -d _build -cp .:/usr/local/Cellar/jython/2.5.3/libexec/jython.jar *.java
java -cp /usr/local/Cellar/jython/2.5.3/libexec/jython.jar:_build org.jython.book.Main
My question is how to locate the jython source anywhere I like and teach java code to find the jython files? 我的问题是如何在我喜欢的任何地方找到jython源并教java代码来查找jython文件?
The setupPath() method should be added into the JythonObjectFactory first. 应首先将setupPath()方法添加到JythonObjectFactory中。
public static void setupPath(String[] paths)
{
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("import sys;");
for (int i = 0; i < paths.length; i++) {
interpreter.exec(String.format("sys.path.append(\"%s\")", paths[i]));
}
}
Then, in the Main function, this function should be invoked. 然后,在Main函数中,应该调用此函数。
public class Main {
public static void main(String[] args) {
JythonObjectFactory factory = JythonObjectFactory.getInstance();
ArithType a = (ArithType) factory.createObject(ArithType.class, "Arith");
String[] paths = {"DIRECTORY1", "DIRECTORY2"};
JythonObjectFactory.setupPath(paths);
