velocity中的velocityCounter不起作用的原因

    今天用org.springframework.ui.velocity.VelocityEngineFactoryBean 时，velocityCounter这个变量的时候死易做图作用，折腾了良久也不行，网上也找不到任何资料。以前用原生态不与spring集成时还没有问题呢，没办法，只有规规矩矩的把源码下载下来跟跟看了。

   最后却发现是原来是配置文件的原因

一部分部分源码

[java]
RuntimeConstants 
 
    /** Counter reference name in #foreach directives. */ 
    String COUNTER_NAME = "directive.foreach.counter.name"; 
 
org.apache.velocity.runtime.directive.Foreach 
 
 
    counterName = rsvc.getString(RuntimeConstants.COUNTER_NAME); 
        counterName = rsvc.getString(RuntimeConstants.COUNTER_NAME); 
        hasNextName = rsvc.getString(RuntimeConstants.HAS_NEXT_NAME); 
        counterInitialValue = rsvc.getInt(RuntimeConstants.COUNTER_INITIAL_VALUE); 
 if (!"velocityCount".equals(counterName)) 

RuntimeConstants

    /** Counter reference name in #foreach directives. */
    String COUNTER_NAME = "directive.foreach.counter.name";

org.apache.velocity.runtime.directive.Foreach

    counterName = rsvc.getString(RuntimeConstants.COUNTER_NAME);
        counterName = rsvc.getString(RuntimeConstants.COUNTER_NAME);
        hasNextName = rsvc.getString(RuntimeConstants.HAS_NEXT_NAME);
        counterInitialValue = rsvc.getInt(RuntimeConstants.COUNTER_INITIAL_VALUE);
 if (!"velocityCount".equals(counterName))
原来这个是变量名可以配置的，而我的配置文件

[java]
<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean"> 
        <property name="resourceLoaderPath" value="classpath*:template" /> 
        <property name="velocityProperties"> 
            <props> 
                <prop key="resource.loader">class</prop> 
                <prop key="class.resource.loader.class">org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader</prop> 
                <prop key="velocimacro.library" /> 
                <prop key="directive.foreach.counter.name">loopCounter</prop> 
                <prop key="directive.foreach.counter.initial.value">1</prop> 
                <prop key="file.resource.loader.cache">true</prop> 
                <prop key="parser.pool.size">50</prop> 
                <prop key="input.encoding">UTF-8</prop> 
                <prop key="output.encoding">UTF-8</prop> 
            </props> 
        </property> 
    </bean> 

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
  <property name="resourceLoaderPath" value="classpath*:template" />
        <property name="velocityProperties">
   <props>
    <prop key="resource.loader">class</prop>
    <prop key="class.resource.loader.class">org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader</prop>
    <prop key="velocimacro.library" />
    <prop key="directive.foreach.counter.name">loopCounter</prop>
    <prop key="directive.foreach.counter.initial.value">1</prop>
    <prop key="file.resource.loader.cache">true</prop>
    <prop key="parser.pool.size">50</prop>
    <prop key="input.encoding">UTF-8</prop>
    <prop key="output.encoding">UTF-8</prop>
   </props>
  </property>
    </bean>
配置成了loopCounter，所以必须用loopCounter才行。
