java - 从java导入django模块

Question

我正在尝试使用 Java 调用 django 项目中的一些类。这是我的代码:

PythonInterpreter interpreter = new PythonInterpreter();

        PySystemState sys = Py.getSystemState(); 


        sys.path.append(new PyString("/Library/Python/2.7/site-packages/"));
        sys.path.append(new PyString("/myApps/categoryApp/review/"));

        interpreter.exec("from products.models import Category");

但是我收到了这个错误:

Exception in thread "main" Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/myApps/categoryApp/review/products/models.py", line 4, in <module>
    from django.core.exceptions import ValidationError
  File "/Library/Python/2.7/site-packages/django/core/exceptions.py", line 4, in <module>
    from functools import reduce
ImportError: cannot import name reduce

有办法解决吗？我相信进口有问题

Jython 的标准版本与 Python 2.5 兼容。如 documentation on running Django on Jython 中所述，Django 1.5仅兼容Python 2.6以上。您将需要运行 Jython 2.7 beta 版本，或 Django 较旧的 1.4 版本。
