CDI 与 Tomcat 8 兼容吗？
如果是，请提供如何通过工作示例实现它。
提前致谢。
不，CDI 不适用于 Tomcat 8，至少不是开箱即用的。据我所知，您可以通过添加各种依赖项（例如 weld）来让它工作。参见例如https://musingsinjava.wordpress.com/2014/11/02/enabling-jsf-2-2-and-cdi-1-2-on-tomcat-8/ and How to install and use CDI on Tomcat?。
就个人而言，我从来没有设法让它工作，相反，我使用了 Apache TomEE，它已经具有 CDI 工作所需的依赖项。 TomEE 网站上有很多示例：http://tomee.apache.org/examples-trunk/index.html
