javaweb项目部署到服务器后，定时任务执行两次

我的解决方法是修改tomcat/conf/server.xml

 <Host name="域名"  appBase="" //这里为空
            unpackWARs="true" autoDeploy="true">

        <!-- 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" />
		<Context path="" docBase="D:\apache-tomcat-7.0.53-windows-x64\apache-tomcat-7.0.53\webapps\项目名称" debug="0" reloadable="true"></Context>
      </Host>
