我正在尝试使用 JSF、JPA、Spring 构建一个项目，但我无法成功。我使用 JBoss 作为我的服务器。它显示没有错误，但显示 404 错误。有趣的是，当我使用 Tomcat 时，控制台是清晰的，但是在加载页面上它显示，

解析 /index.xhtml 时出错：不支持设置属性http://xml.org/sax/properties/lexical-handler

这是完整的堆栈跟踪

此错误来自pull-parser它的可选依赖项dom4j。您可能无意中在您的类路径上获得了 pull-parser，即使它对于 dom4j 是可选的。尝试显式排除它并改用 JDK 的内置解析器（例如com.sun.org.apache.xerces.internal.parsers.SAXParser），它应该在默认情况下执行此操作。

这个问题已有 6 年历史，因此以下问题不可能是问题，但是：在我的 Gradle 项目中，从 Gradle 5.4 升级到 Gradle 6.5 突然导致pull-parser由于依赖于类路径，dom4j尽管如上所述，依赖于dom4jonpull-parser是可选的，以前没有发生。我已将此报告给 Gradle 项目：https ://github.com/gradle/gradle/issues/13656 。

我通过添加以下依赖项（在 Gradle 语法中）摆脱了错误：

implementation 'pull-parser:pull-parser:2.1.10'
