tomcat无需项目名即可访问该项目配置

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

			<Context path="" docBase="/twithandSite"/>

      </Host>

由于path=""，所以项目中

	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort();
	request.setAttribute("base", basePath);

得到的 request.getContextPath()=null;

访问地址：从http://192.168.0.27:8080/twithandSite变为：ttp://192.168.0.27:8080
