最后发现是tomcat安装目录/conf/server.xml配置的问题：

因为我之前配置了:

    <Engine>
      <Host name="127.0.0.1" debug="0" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false"  xmlNamespaceAware="false">
        <Context path="" docBase="call" debug="0" reloadable="true" crossContext="true"/>
        <Logger className="org.apache.catalina.logger.FileLogger" directory="logs" prefix="tot_log." suffix=".txt" timestamp="true"/>
      </Host>
    </Engine>
