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

Question

我正在嘗試生成Java類來將xml綁定到使用腳輪的對象。這件作品的XML，我想要綁定的是Spring的XML文件，所以我採取了DTD和生成使用蓖麻油提供的工具的XSD，但一旦我嘗試生成源文件，我收到以下錯誤

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

這裏是我已生成XSD文件：

有沒有人遇到了類似的問題，並知道有什麼方法可以解決這一問題？

Answer 1

對於混凝土腳輪問題，我想你應該提供更多的信息。看起來有一個重複的字段，所以繼續並逐個刪除每個「鍵」屬性，直到它開始工作。

但是這是一件奇怪的事情，你正試圖做。 Spring的DTD/XSD旨在提供XML配置 - 它們不應該代表對象。如果要使用代碼而不是xml配置spring，請使用javaconfig。
