是否可以从spring-beans.dtd生成的spring-beans.xsd生成java源文件？

Question

我正在尝试生成Java类来将xml绑定到使用脚轮的对象。这件作品的XML，我想要绑定的是Spring的XML文件，所以我采取了DTD和生成使用蓖麻油提供的工具的XSD，但一旦我尝试生成源文件，我收到以下错误

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

这里是我已生成XSD文件：

有没有人遇到了类似的问题，并知道有什么方法可以解决这一问题？

Answer 1

对于混凝土脚轮问题，我想你应该提供更多的信息。看起来有一个重复的字段，所以继续并逐个删除每个“键”属性，直到它开始工作。

但是这是一件奇怪的事情，你正试图做。 Spring的DTD/XSD旨在提供XML配置 - 它们不应该代表对象。如果要使用代码而不是xml配置spring，请使用javaconfig。
