按常规配置方式 在 server.xml里添加如下 配置 ：

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"                maxThreads="150" scheme="https" secure="true"                keystoreFile="conf/cnzz.freeca.cn.jks" keystorePass="123"                clientAuth="false" sslProtocol="TLS" />

启动 Tomcat 7，会发现443端口无法正式启动下面是启动日志：

分析：

方法：

在 Tomcat 中注释掉 下面的配置：

<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> 

重新启动 Tomcat ，443已经能正常启动，再看下日志：
