Tomcat 部署java web项目直接ip地址访问项目

正常情况下，在访问在Tomcat中部署的项目是 http://localhost:8080/demo 方式

其中，IP，端口，项目名(Demo)都是必须的。

那么，怎么样才能通过 http://localhost 就能直接访问我们的项目呢？

修改 Tomcat/conf/server.xml文件

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->
        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"  
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
        -->
      </Host>

更改为

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

        <Context path="" docBase="Demo" reloadable="true" />
        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->
        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"  
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
        -->
      </Host>

这样就可以通过 http://localhost:8080 访问项目(Demo)了，省去了项目名。。。

然后修改端口，

    <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

更改为80端口：

    <Connector port="80" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

就可以通过 http://localhost 访问了。。。
