我有 SpringBoot应用程序（1.4.3.RELEASE）。最近我已经将Jackson（com.fasterxml.jackson.datatype, com.fasterxml.jackson.core）从2.8.5升级到2.12.2，因为有多态子类型演绎功能。在单元测试期间，以及从IDE运行应用程序时，在我的本地开发环境中一切都运行良好。
当我推送我的更改以在开发环境中构建和部署它时，出现了这个问题，其中应用程序部署在 Wildfly 21.0.2 上（作为WAR存档）。调用ObjectMapper#readValue会引发java.lang.EnumConstantNotPresentException（下面详细介绍了堆栈）。
我正在反序列化的对象中没有使用枚举，我已经通过Wildfly管理控制台检查了，在部署的应用程序上有正确的Jackson版本。现在我有点不知所措。有什么想法吗？

好吧，通过在jboss-deployment-structure.xml文件中显式排除Jackson相关库，解决了该问题（如下面的代码所示）。如果没有这些排除，Wildfly将强制其自己的Jackson库，该库位于
/wildfly/modules/system/layers/base/ path (e.g. wildfly/modules/system/layers/base/com/fasterxml/jackson/core/jackson-core)中，对于Wildfly 21.0.2为2.10.5。Wildfy将这样做，而不考虑在maven pom.xml中指定自定义版本。此外，我没有"我无法通过管理控制台在Wildfly中找到任何关于这个"嵌入式" Jackson版本的内容，所以要意识到问题出在哪里有点痛苦。也许这会为其他人节省一些时间。
