好的，我在stackoverflow上搜索了有关这个问题的未回答的子主题，因此我希望这个问题能够清楚地指出：
有没有工具可以从xsd模式生成Simple Xml库的注释Java类？
我收到了描述由他人开发的restful web-service返回对象的几个xsd文件，目前我已将这些模式转换为simple-xml注释类。这些类将用于我的Android应用程序。最好自动同步模式中的任何更改，并从中重新生成类。ws团队对这些模式有符合Jackson要求的类的存储库，但我不想使用Jackson - 我正在使用Spring Android，因此我更喜欢使用首选的simple-xml。一定有一些像JAXB的xjc工具一样做到这一点的工具。
如果没有这样的工具，您是否能想到实现生成simple-xml .java文件的脚本时遇到的任何陷阱？也许有值得扩展的工具的提示，只需要定义要生成的注释以及何时生成就可以了吗？
提前感谢您的答案！

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行的。 我不认为您应该担心Web服务实现者对模式进行的更改，因为如果他们进行更改，您将无论如何需要重新生成客户端部分。 无论如何，一旦部署了Web服务，模式就不会经常更改，否则所有客户端应用程序都将受到影响。
如果您想创建自己的工具，则必须创建一个代码生成器，该生成器将解析xsd文件并为Simple XML创建带注释的类。 这对我来说似乎需要很多努力。
希望这有所帮助
