我一直在 jsf 2.2 应用程序中使用omnifaces，没有出现任何问题，直到我决定从 tomee Web Profiler 迁移到 jetty (9.0.7)。似乎存在一些注释和 CDI 相关问题，导致 Weld (2.1.2.Final) 和 Omnifaces (1.7) 无法很好地配合，我在 Omnifaces 中使用的唯一功能是隐藏 URL 中的扩展名。
项目设置的简要 View :
相关 POM 依赖项:
<!--OmniFaces-->
<dependency>
<groupId>org.omnifaces</groupId>
<artifactId>omnifaces</artifactId>
<version>1.7</version>
</dependency>
<!--Weld for cdi in jetty-->
<dependency>
<groupId>org.jboss.weld.servlet</groupId>
<artifactId>weld-servlet</artifactId>
<version>${weld.version}</version>
<scope>runtime</scope>
</dependency>
在 web.xml 中:
<context-param>
<param-name>org.omnifaces.FACES_VIEWS_SCAN_PATHS</param-name>
<param-value>/*.xhtml</param-value>
</context-param>
所有与 Weld 相关的内容都在 override-web.xml 中(在 web.xml 之后解析):
<!--WELD-->
<listener>
<listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
</listener>
<resource-env-ref>
<resource-env-ref-name>BeanManager</resource-env-ref-name>
<resource-env-ref-type>
javax.enterprise.inject.spi.BeanManager
</resource-env-ref-type>
</resource-env-ref>
<!--weld complains if the following is not done manually :-S-->
<listener>
<listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>
我试图让我的应用程序摆脱不必要的 xml 配置，并且到目前为止我已经设法做到了这一点，如果我通过将以下内容放入 beans.xml 来指示 Weld 排除 Omnifaces 中有问题的类:
<scan>
<exclude name="org.omnifaces" />
<exclude name="org.omnifaces.cdi.param.RequestParameterProducer"/>
<exclude name="org.omnifaces.validator.JsfLabelMessageInterpolator"/>
<exclude name="org.omnifaces.util.Platform"/>
</scan>
然后一切都运行良好，omnifaces 完成它的工作，并从 url 中删除扩展名，并且 Weld 不会提示任何事情，所以我的问题是这是否是目前唯一的方法，或者是否有更好的方法解决这个问题而不污染我的 beans.xml？
这是我在执行 mvn jetty:run 时遇到的异常的副本:

最佳答案
Caused by: java.lang.ClassNotFoundException: javax.validation.ConstraintViolation
Caused by: java.lang.ClassNotFoundException: javax.validation.MessageInterpolator
Caused by: java.lang.ClassNotFoundException: javax.validation.ValidatorFactory
导致这些问题的原因是运行时类路径中不存在 JSR303 Bean Validation API，而那些 OmniFaces CDI bean 期望它存在。这确实是 OmniFaces 依赖文档中的一个不清楚之处。我们将对此进行研究。
除了明确排除这些类被扫描为 CDI 托管 bean 之外，您还可以考虑实际安装 JSR303 API，如果需要，还可以考虑在 Jetty 中安装 JSR303 实现以及 CDI API/impl。这个答案在 how to install CDI in Tomcat也适用于您的 Jetty 案例。
关于java - 使用omnifaces时 Weld 类加载异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22095634/
