SpringMVC的定時任務執行兩次的問題

有兩種可能：

1，可能和spring配置，web.xml有關系

2，和Tomcat配置有關系,

這裡說一下Tomcat配置的關系，如果你在eclipse上的Tomcat配置deploy路徑為webapp，eclipse會把項目部署的Tomcat webapp目錄下，Tomcat配置如下，tomcat首先掃描到appBase屬性，于是加載了webapps下的目錄，Tomcat又會你配置的deploy路徑又加載一遍deploy下的目錄，是以就會加載兩次（下圖是我改回來了）

<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="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" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log" suffix=".txt"/>

      <Context docBase="spss-authentic" path="/authentic" reloadable="true" source="org.eclipse.jst.jee.server:spss-authentic"/><Context docBase="spss-workduty" path="/workduty" reloadable="true" source="org.eclipse.jst.jee.server:spss-workduty"/></Host>
