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
