Question

在我的wsdl中，我正在定义birthDate元素：

<xs:element minOccurs="0" name="birthDate" type="xs:dateTime"/>

肥皂封套中的这个元素存在但是空的时候会发生什么。

<birthDate></birthDate>

我收到以下异常

org.apache.cxf.interceptor.Fault: Unmarshalling Error:

并在堆栈中进一步向下

但是，只要元素不存在或设置为某种东西，即

<birthDate>1907-07-16T19:20:30</birthDate>

一切正常。

令人困惑的是，只有在Windows下工作时才会出现此问题。 Linux下没有问题。

什么可能导致这种奇怪？我该如何解决它？

谢谢。

根据this JIRA on the Apache site，其中列出了一个非常类似的例外：

<ns2:SUBMITDATE></ns2:SUBMITDATE>不会使其为空。这使得它成为一个空字符串，对于日期无效，JAXB在这种情况下正确抛出IllegalArgumentException。如果你想要它null，它应该是： <ns12:SUBMITDATE xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/> 因此，传入的XML对于每个模式都是无效的，并且CXF / JAXB按设计工作。

不确定为什么它可以在Linux上运行，但不能在Windows上运行。

Windows下的cxf 2.7.7无法处理dateTime元素
