好的，所以我搜索了 stackoverflow 并找到了关于这个问题的未回答的子主题，这就是为什么我想明确指出这个问题：
是否有任何工具可以从 xsd 模式生成Simple Xml library的带注释的 java 类？
我收到了几个 xsd 文件，这些文件描述了其他人开发的 restful web 服务返回的对象，目前我已经将这些模式转换为 simple-xml 注释类。这些将在我的 Android 应用程序中使用。最好只自动同步对模式的任何更改并从中重新生成类。ws 家伙有一个用于这些模式的 Jackson 兼容类的存储库，但是我不想使用 Jackson - 我使用的是 Spring Android，所以我更喜欢使用首选的simple-xml。一定有像 JAXB 的 xjc 工具这样的东西。
如果没有这样的工具——你能想到在实现从模式中为simple-xml生成 .java 文件的脚本时有什么陷阱吗？也许任何值得扩展的工具的提示只需要定义要生成哪些注释以及何时生成？
提前 - 非常感谢您的回答！
我编写了一个库来从 XSD 生成 SimpleXML Java 注释类。

据我所知，Simple XML 用于创建带注释的类来编组/解组 XML。
Java Web 服务框架，使用特定绑定：
例如 CXF 支持（除了 JAXB）Aegis、XML Beans 等CXF 数据绑定
Axis2 支持 ADB、XMLBeans 等Axis2 数据绑定
JAX-WS 相同
我不了解 Spring WS（但我怀疑他们支持特别简单）
恕我直言，如果您绝对需要使用简单 XML，只需自己创建类。这在您的情况下似乎是可行的，因为您注意到：
I received a couple of xsd files describing the objects returned by a restful web-service
所以对于一些文件可能是可能的。我认为您不应该担心 Web 服务实现者对模式的更改，因为如果他们进行更改，您无论如何都必须重新生成您的客户端部分。在任何情况下，一旦部署了 Web 服务，架构就不会经常更改，否则所有客户端应用程序都会受到影响。
如果您想创建自己的工具，则必须创建一个代码生成器来解析 xsd 文件并为 Simple XML 创建带注释的类。在我看来，这需要付出很多努力
希望这会有所帮助
