在eclipse中用java调用python报错 Exception in thread "main" ImportError: Cannot import site module and its dependencies

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
