推荐答案

JAR 文件包含一个 META-INFservices 目录，其中包含将覆盖服务器正在使用的 XML 处理器的文件.

The JAR file includes a META-INFservices directory which includes files that will override the XML processors being used by your server.

来自 Java SE javadoc

From Java SE javadoc

如果可用，请使用服务 API(如 JAR 规范中所述)来确定类名.服务 API 将在运行时可用的 jar 中的 META-INF/services/javax.xml.parsers.SAXParserFactory 文件中查找类名.

Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.parsers.SAXParserFactory in jars available to the runtime.

我使用 7-zip 从 META-INFservices 中删除文件并改用那个 JAR.我的 XML 对象解析现在可以正常工作，其他所有内容均未受影响.

I used 7-zip to delete the files from the META-INFservices and used that JAR instead. My XML Object parsing works now and everything else is un-effected.
