Java 使用spring任务计划程序时将字符串强制转换为长字符串时出错

我有一个应用程序正在从spring 3.0.5.RELEASE和spring integration 2.0.3.RELEASE升级到spring 3.1.1.RELEASE和spring integration 2.1.3.RELEASE

更改POM后，运行测试时出现以下错误

以下代码是问题的根源

    if (this.fixedRateTasks != null) {
        for (Map.Entry<Runnable, Long> entry : this.fixedRateTasks.entrySet()) {
            this.scheduledFutures.add(this.taskScheduler.scheduleAtFixedRate(entry.getKey(), entry.getValue()));
        }
    }

if（this.fixedRateTasks！=null）{
对于（Map.Entry:this.fixedRateTasks.entrySet（））{
this.scheduledFutures.add（this.taskScheduler.scheduleAtFixedRate（entry.getKey（），entry.getValue（））；
}
}

我在spring集成xml配置文件中追溯到以下xml

<task:scheduled-tasks scheduler="taskScheduler">
    <task:scheduled ref="searchAggregatorReaper" 
                    method="run"
                    fixed-rate="500"
</task:scheduled-tasks>

虽然看起来确实如此，但你确定你的错误真的来自于此吗？快速浏览一下，您会发现您正按照预期使用固定利率……Joel感谢您的回复，我确信这就是问题所在，因为当我将XML更改为XML时，问题就消失了
