tomcat启动timer定时器会执行两次问题解决方案

在网上找了一通，发现还是配置文件的问题，于是，在tomcat的server.xml中将appBase修改成空，问题得到解决

 <Host name="localhost"  appBase=""

            unpackWARs="true" autoDeploy="true">

                <Context docBase="/usr/local/apache-tomcat-7.0.59/webapps/***" path="" reloadable="true">

                </Context>

        <!-- 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>
