com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl 与 javax.xml.stream.XMLOutputFactory 不兼容
com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl 与 javax.xml.stream.XMLInputFactory 不兼容
从 APP(Web-inf/lib) 中删除了具有“XMLOutputFactory”和“XMLInputFactory”类的“jsr173_1.0_api.jar”、“stax-api-1.0-2.jar”以避免与服务器版本发生任何冲突。
还在 WebSphere 管理控制台中将 war 类加载器顺序更改为“最后一个父级”，并将策略更改为“应用程序的单个类加载器”。已进行此更改以优先考虑应用程序 jarWebInf/lib而非服务器 jar。
下面是堆栈跟踪。

在对类加载问题进行故障排除时，您可能需要覆盖对父类加载器可见的类。要使用特定于应用程序的类来覆盖此类类，请将类加载器模式设置为 Parent last 在包含其类路径中的应用程序类的类加载器上。应用程序可以覆盖对父类加载器可见的类，但如果混合使用覆盖类和非覆盖类，这样做可能会导致 ClassCastException 或 UnsatisfiedLinkError。
