在一个tomcat下面布置2个项目
项目的访问路径:
http://localhost:8081/
http://localhost:8082/
1.建立两个站点（虚拟目录，目录中必须包含必要的配置文件WEB-INF）
2.修改tomcat配置文件server.xml，在server下，放置多个service即可。在service的平级上 添加如下配置：
<Service name="Catalina2">
<Connector port="8082" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
URIEncoding="UTF-8"/>
<Engine name="Catalina2" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
</Realm>
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
<Context path="" reloadable="true" docBase="D:/Environments/webSite2" workDir="D:/Environments/webSite2/work"></Context>
</Host>
</Engine>
</Service>
3.启动tomcat
