最佳答案
您正在使用 JSF 2.1 实现，但已将 faces-config.xml 文件配置为旧的 JSF 1.2:
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd"
version="1.2">
^here's the main problem
只需将 faces-config.xml 文件更新为正确的 JSF 版本即可:
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
或者更好的是，如果您要使用任何特定配置(例如注册阶段监听器)，只需将其删除并仅添加即可。您可以在此处找到此文件的更多用例:What is the use of faces-config.xml in JSF 2? .
除此之外，还有其他主要问题:
- JSF 2.x 至少需要 Servlet 2.5，该版本自 JBoss 5 起可用。请参阅 StackOverflow JSF wiki有关此主题的更多信息。
- 您当前正在学习的教程涉及 JSF 1.2，它已经很旧了。 JSF 2.0 自 2009 年以来已发布。我建议停止遵循本教程并转向更新的教程，如 mkyong's tutorial on JSF 2 .
如果您确实想坚持使用 JSF 1.2 来满足特定要求(例如维护遗留应用程序)，请将 JSF 库从 2.1 替换为 1.2。
