我有一个相当大的Java应用程序，它使用一些作业和大量的http和db活动。这个应用程序是使用maven构建的，具有相当多的依赖关系，并在tomcat 6上运行 - 好处是，它的工作原理。jsf（像servlet）的依赖关系阻止应用程序启动
不过，我现在想添加一些JSF的功能，也就是我希望能够手动启动，并从网站停止工作石英，所以我激活我的pom.xml两个依赖：
<!-- to get the servlet container -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>
<!-- To work with java server faces -->
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.2.7</version>
</dependency>
这样做后，我的应用程序不再出现。它开始了，但我没有看到任何通常的调试信息，告诉我该应用程序实际上在做某些事情。它也不会崩溃。它似乎坐在那里，什么都不做。奇怪的是，java类使用这些依赖关系甚至没有开始。
谁能告诉我，JSF是什么？我必须做一些故障切换配置，或什么？
我将附加一个正常的启动日志和激活这两个依赖关系后的日志。
正常启动：
