最近做项目需要用java调用python，配置了jython后，运行了例子代码：
获得一个元组里面的元素：
import org.python.util.PythonInterpreter; public class FirstJavaScript { public static void main(String args[]) { PythonInterpreter interpreter = new PythonInterpreter(); interpreter.exec("days=(‘mod‘,‘Tue‘,‘Wed‘,‘Thu‘,‘Fri‘,‘Sat‘,‘Sun‘); "); interpreter.exec("print days[1];"); }// main }
运行时报错：
Exception in thread "main" ImportError: Cannot import site module and its dependencies: No module named site
Determine if the following attributes are correct:
* sys.path: [‘C:\\（你的项目地址）‘, ‘__classpath__‘, ‘__pyclasspath__/‘]
This attribute might be including the wrong directories, such as from CPython
* sys.prefix: C:（你的项目地址）
This attribute is set by the system property python.home, although it can
be often automatically determined by the location of the Jython jar file
You can use the -S option or python.import.site=false to not import the site module
我们只需要把代码改为以下这个例子就可以顺利执行了。
Properties props = new Properties(); props.put("python.home", "path to the Lib folder"); props.put("python.console.encoding", "UTF-8"); props.put("python.security.respectJavaAccessibility", "false"); props.put("python.import.site", "false"); Properties preprops = System.getProperties(); PythonInterpreter.initialize(preprops, props, new String[0]); PythonInterpreter interpreter = new PythonInterpreter(); interpreter.exec("days=(‘mod‘,‘Tue‘,‘Wed‘,‘Thu‘,‘Fri‘,‘Sat‘,‘Sun‘); "); interpreter.exec("print days[1];");
执行结果是Tue
