Win 7 启动tomcat 时 报Unrecognized Windows Sockets error: 0: JVM_Bind，可通过更改conf 目录下的server.xml 定义的三个接口解决：

<Server port="8009" shutdown="SHUTDOWN">

<Connector port="8090" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

<Connector port="8099" protocol="AJP/1.3" redirectPort="8443" />
