如何使用Spring 3.0表达式语言参数化@Scheduled（fixedDelay）？(How to parameterize @Scheduled(fixedDelay) with Spring 3.0 expression language?)

 当使用Spring 3.0功能来注释计划的任务时，我想将fixedDelay设置为我的配置文件中的参数，而不是将其fixedDelay到我的任务类中，如当前的... 
 
@Scheduled(fixedDelay = 5000)
public void readLog() {
        ...
}
 
 不幸的是，似乎使用Spring表达式语言（Spel）的方式@Value返回一个String对象，而该对象又不能根据fixedDelay参数的要求自动装箱到一个较长的值。 

When using the Spring 3.0 capability to annotate a scheduled task, I would like to set the fixedDelay as parameter from my configuration file, instead of hard-wiring it into my task class, like currently...
 
@Scheduled(fixedDelay = 5000)
public void readLog() {
        ...
}
 
Unfortunately it seems that with the means of the Spring Expression Language (SpEL) @Value returns a String object which in turn is not able to be auto-boxed to a long value as required by the fixedDelay parameter.
