How to install and use CDI on Tomcat?(2个答案)
上个月关门了。
我对JSF开发完全陌生,在部署到Tomcat 9.0.80时遇到以下异常:

我在网上(包括stackoverflow)寻找答案,但所有的答案都超出了我的想象。我看过的一些链接(其解决方案显然对我不起作用):

有没有人能用简单的话告诉我:
1.我做错了什么
1.如何解决上述问题

按热度按时间iyzzxitl1#
由于您使用的是Tomcat(servlet容器),那么您将得到此错误,因为Tomcat默认不支持完整的Java EE功能,包括CDI。
您可以通过以下Maven依赖项包含Weld(一个CDI实现):
这也是JBoss的官方网站。这可能是值得一看和使用,因为它可能是更当前。
我已经很多年没有接触过JSF了,所以这些仅仅是建议。
在添加所需的依赖项后,尝试向web.xml添加侦听器:
**旁注:**如果你还没有与Tomcat结婚,我建议你使用一个完整的EE实现服务器,比如WildFly或Payara。所有这些功能都是开箱即用的。
