java - 使用 intelliJ 从 xsd 生成 java 类

Question

我正在尝试使用 IntelliJ 从一些 xml 创建 java 类 - 我正在执行的步骤如下:

1. 通过浏览器保存来自指定合作伙伴 url 的 xml
2. 使用 IntelliJ 从 XML 文件生成 XSD 模式
3. 使用 IntelliJ 从 xsd 文件生成 java 类

我的问题是，唯一发生的事情是它创建了指定的包并将 xsd 复制到这个包 - 没有生成任何 java 类。

我下载的 xml 看起来像这样

有人可以向我解释为什么我不能从上面生成 java 类吗？？

Answer 1

这是因为 xsd 中的以下行

<xs:attribute type="xs:float" name="value" use="optional"/>

因为值已经在某处的“datatypes.jar”中定义
