主要配置tomcat/conf目录下的server.xml文件
1、先找到8080端口，把端口改为80。
<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Documentation at :
Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
Java AJP Connector: /docs/config/ajp.html
APR (HTTP/AJP) Connector: /docs/apr.html
Define a non-SSL HTTP/1.1 Connector on port 8080
-->
<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<!-- A "Connector" using the shared thread pool-->备注：设置Connector 节点的port="80"。
2、配置项目目录访问。
<Host name="localhost" appBase="webapps/lotter"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="lottery" />
<!--<Context path="/lottery" docBase="." /> -->
lottery”，webapps应用程序目录，这里我设置的是webapps/lottery的相对目录。项目绝对路径就是(D:/apache-tomcat-7.0.65/webapps/lottery)也就是tomcat下的webapps下的i18n部署的项目目录。
3、tomcat启动时项目重复加载两次
appBase="webapps"配置可有可无。将项目lottery放在webapps同一路径下
<Host name="localhost" unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="D:/apache-tomcat-7.0.65/lottery" debug="0" reloadable="true" />
