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

Question

我正在尝试使用 JSF、JPA、Spring 构建一个项目，但无法成功。我使用 JBoss 作为我的服务器。没有显示任何错误，但显示 404 错误。有趣的是，当我使用 Tomcat 时，控制台很清晰，但在加载页面上显示，

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

这是完整的堆栈跟踪

Answer 1

此错误来自于pull-parser的可选依赖项dom4j。您可能会无意中在类路径上获得 pull-parser，即使它对于 dom4j 来说是可选的。尝试显式排除它并使用 JDK 的内置解析器（例如com.sun.org.apache.xerces.internal.parsers.SAXParser），默认情况下应该这样做。

这个问题已经有 6 年历史了，所以以下不可能是问题，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出现在类路径上，因为dom4j即使如上所述，依赖项dom4jonpull-parser是可选的，以前不会发生这种情况。我已将此问题报告给 Gradle 项目：https ://github.com/gradle/gradle/issues/13656 。

Answer 2

我通过添加以下依赖项（在 Gradle 语法中）来消除错误：

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