Eclipselink 未正确处理时区偏移

【问题描述】：

我正在使用部署到 Weblogic 12.1.3.0.0 的 Spring Boot。我在 XML 输入中解组日期的方式遇到问题。

我提供了有效的 ISO-8601 日期，而时区偏移的格式导致 org.eclipse.persistence.exceptions.ConversionException。

从堆栈跟踪中，它显示 eclipselink 的版本为：eclipselink.jar:2.5.2.v20140319-9ad6abd

这个日期处理正确：

2015-11-02T11:15:47.239-05:00

虽然这会导致异常：

2015-11-02T11:15:47.239-0500

根据spec，两者都是有效的。

提供的 Jackson unmarshaller 可以正确处理这种格式。

我不能要求客户重新格式化输入，因为当客户在 Accept-Type 中请求 application/json 时，这种格式是默认输出。

我需要换掉eclipselink吗？

    【解决方案1】：

    代码显示 EclipseLink 正在使用 DatatypeFactoryImpl 并将字符串传递给 newXMLGregorianCalendar 方法。我found 的链接声明它匹配newXMLGregorianCalendar(x).toXMLFormat().equals(x)，newXMLGregorianCalendar 的javadoc 使用http://www.w3.org/TR/xmlschema-2/#isoformats 指向它，它不涵盖iso 8601 的所有词汇表示。

    我不知道是否有办法更改内部用于转换的实现 - 更有知识的人可能会提供进一步的帮助。但是您可以通过在映射上定义 XmlAdapter 来更改使用的内容，以便为您处理格式。
