我的问题是解析具有大于 5000 的 maxOccurs
元素(但不是 unbounded
)的 XSD 架构.
My problem is with parsing an XSD Schema that has elements with maxOccurs
larger than 5000 (but not unbounded
).
这实际上是 Xerces(我正在使用,版本 2.9.1)或 JAXP 中的一个已知问题,如下所述:http://bugs.sun.com/view_bug.do;jsessionid=85335466c2c1fc52f0245d20b2e?bug_id=4990915
This is actually a know issue in either Xerces (which I'm using, version 2.9.1) or JAXP, as described here: http://bugs.sun.com/view_bug.do;jsessionid=85335466c2c1fc52f0245d20b2e?bug_id=4990915
我已经知道,如果我将 XSD 中的 maxOccurs 数字从大于 5000 的数字更改为 unbounded
一切正常.可悲的是,这不是一个选项,就我而言(我不能干预 XSD 文件).
I already know that if I changed the maxOccurs numbers in my XSD from numbers larger than 5000 to unbounded
all works well. Sadly, this is not an option in my case (I cannot meddle with the XSD file).
我的问题是:
谢谢!
我找到了一个不需要更改解析器的解决方案.
I have found a solution that doesn't require changing the parser.
有一个 FEATURE_SECURE_PROCESSING
功能 将 maxOccurs 限制为 5000(以及其他几个).
There is a FEATURE_SECURE_PROCESSING
feature which puts that 5000 limitation on maxOccurs (along with several others).
这里是描述限制的文档:http://docs.oracle.com/javase/7/docs/technotes/guides/xml/jaxp/JAXP-Compatibility_160.html#JAXP_security
And here is the document describing the limitations: http://docs.oracle.com/javase/7/docs/technotes/guides/xml/jaxp/JAXP-Compatibility_160.html#JAXP_security
这篇关于XMLSchema 的解决方法不支持 maxOccurs 大于 5000的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
