    text
    copied!<p>I am using Spring 3 to create a scheduled-task.</p> <p>I have to use XML based wiring to configure it, and would like scheduled task to run with an interval that is set in a properties file.</p> <p>Spring Context file:</p> <pre><code>&lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.1.xsd" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task"&gt; &lt;context:property-placeholder location="classpath:connector.properties"/&gt; &lt;task:scheduler id="connectorScheduler" pool-size="10"/&gt; &lt;task:scheduled-tasks scheduler="connectorScheduler"&gt; &lt;task:scheduled ref="connector" method="checkConnection" fixed-rate="${connector.connectionAttemptDelayMillis}"/&gt; &lt;/task:scheduled-tasks&gt; &lt;bean id="connector" class="com.test.Connector" scope="singleton"&gt; &lt;constructor-arg index="0" value="${connector.user}"/&gt; &lt;constructor-arg index="1" value="${connector.password}"/&gt; &lt;constructor-arg index="2" value="${connector.connectionAttemptDelayMillis}"/&gt; &lt;/bean&gt; &lt;/beans&gt; </code></pre> <p>The problem is that the ${connector.connectionAttemptDelayMillis} is not allowed in the fixed-rate value. This will work fine if i was to put a number in its place, but i need this value to come from a loaded property file.</p> <p>Any help is much appreciated.</p>
