Можно ли сгенерировать исходные файлы Java из файла spring-beans.xsd, созданного из файла spring-beans.dtd?

Question

Я пытаюсь сгенерировать классы Java для привязки XML к объектам с помощью Castor. Кусок xml, который я пытаюсь связать, представляет собой весенний xml-файл, поэтому я взял dtd и сгенерировал xsd, используя предоставленный инструментальный ролик, но как только я пытаюсь сгенерировать исходные файлы, я получаю следующую ошибку

    java.lang.IllegalArgumentException: Duplicate name found as a class member: _key

Вот файл xsd, который я сгенерировал:

Кто-нибудь сталкивался с подобной проблемой и знает, как это исправить?

Answer 1

Я полагаю, что для проблемы с бетонным колесом вы должны предоставить больше информации. Кажется, есть дублирующее поле, так что убирайте каждый атрибут "ключ" один за другим, пока он не начнет работать.

Но это странная вещь, которую вы пытаетесь сделать. DTD/XSD Spring предназначены для предоставления конфигурации XML - они не должны представлять объекты. Если вы хотите настроить Spring с кодом, а не с XML, используйте javaconfig.
