Tomcat 映射虚拟目录

tomcat的conf目录下的server.xml文件中

<!-- <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"> 
		恢复默认要取消这边的注释	
	   -->

        <!-- 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
             Note: The pattern used is equivalent to using pattern="common" -->
     
	 <!--   <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
	 
      </Host>
	   恢复默认要取消这边的注释
	   -->
	    <!-- 配置虚拟路径 -->
	  <Host name="localhost" appBase="webapps"></Host>
	  <Host name="www.juyuanmeihui.com" appBase="juyuanmeihui">
		  <Context path="/" docBase="D:JYCJshopWebContent" ></Context> 
	  </Host>

然后修改host文件

#默认配置，不必修改
127.0.0.1       localhost
127.0.0.1	www.juyuanmeihui.com

这时只需要运行tomcat而且不需要部署这个项目　

如图

　

但是可能会出现下面这种情况

严重: Error configuring application listener of class com.enation.eop.sdk.listener.EopSessionListener
java.lang.ClassNotFoundException: com.enation.eop.sdk.listener.EopSessionListener

class文件找不到报异常

这时关闭tomcat，设置项目的class输出目录，设置为javamall/WebContent/WEB-INF/classes

然后确定，重启tomcat即可，这时你可以通过访问

www.juyuanmeihui.com来访问本地的javamall项目了。
