Answer 1

应该是你的eclipse装的有问题，缺失某些文件

Answer 2

JDK、Tomcat的环境变量配置
path、classpath、TOMCAT_HOME、CALINA_BASE、CATALINA_HOME看看有没有正确配置。
classpath中几个api有没有添加进去

Answer 3

tomcat 下的conf下server.xml中查看是否有这行，如果有，则注释掉
<Listener className="org.apache.catalina.core.AprLifecycleListener"/>

Answer 4

java.lang.ClassNotFoundException: org.apache.catalina.core.AprLifecycleListener找不到上面说的这个类。

Answer 5

java.lang.ClassNotFoundException: org.apache.catalina.core.AprLifecycleListener
丢东西了吧，重装？
