获取类的反射信息时出错

Question

我正在 Wildfly 10.1.0 中运行动态 Web 项目。我的 WEB-INF\lib 文件夹中有richfaces-ui.3.3.3.jar，但我仍然收到此错误。

我的 web-inf 文件夹中包含了这个库

Answer 1

来自 Wildfly.org 网页：

Java 7 支持已停止，允许更深入 与 Java 8 运行时集成。虽然 Java 9 仍在 开发，此版本在当前开发快照上运行。

请确保您使用 Java 1.8 构建您的战争

Answer 2

当我不小心部署了 JAR 文件而不是 WAR 文件时，我收到了这个错误。有时要找出如此简单的故障并不容易。 也许这是你的情况？ 祝你好运。

Answer 3

如果您的 java 类引用了一些 jar 或 xml 文件，例如 persistence.xml 并且不存在，则会出现此错误

Answer 4

就我而言，当我尝试部署战争文件时，它给了我您所指的错误。 问题是有一条线叫做 java.lang.**NoClassDefFoundError**: Lorg/richfaces/component/html/HtmlDataTable; at java.lang.Class.getDeclaredFields0(Native Method)

这意味着wildfly正在寻找 Lorg/richfaces/component/html/HtmlDataTable 它在给定的位置找不到它

你可以检查模块是否真的在那里。如果没有把模块放在正确的位置，它会工作。希望这对某人有帮助
