2.错误原因
和tomcat的版本有关，用apache-tomcat-6.0.48就会出现这个错误。由于apache-tomcat的版本中默认启用了APR，采用传统的配置方式会报错
错误配置：

<Connector port="8443"   protocol="HTTP/1.1" 
           SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           sslProtocol="TLS" URIEncoding="GBK" 
           keystoreFile="F:/Cjava/eclipse/Cworkplace/whggfw-wgbt/web/META-INF/server.keystore"
           keystorePass="hnisi2010"/>

3.解决方法
将protocol="HTTP/1.1"改成protocol="protocol="org.apache.coyote.http11.Http11Protocol"

<Connector port="8443"   protocol="protocol="org.apache.coyote.http11.Http11Protocol"" 
           SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           sslProtocol="TLS" URIEncoding="GBK" 
           keystoreFile="F:/Cjava/eclipse/Cworkplace/whggfw-wgbt/web/META-INF/server.keystore"
           keystorePass="hnisi2010"/>

启动结果：

4.tomcat中的配置文件server.xml有错，运行startup.bat会报错一闪而归
5.用SSL安全连接之后，用http://localhost:8443/运行会显示“网络连接异常、网站服务器失去响应”，应该用https://localhost:8443/进行访问
