我在尝试开发最简单的 jBilling 预定插件时遇到了一个奇怪的问题。我想制作一个每分钟执行一次的插件，但会运行更长的时间。我需要这个来了解 jBilling 将如何以这种方式运行 - 只运行一个插件实例或每分钟启动一个新实例。所以我编写了插件（见下文）并使用 cron_exp = "* * * * " 安装它（我还尝试了 " 0-23 * * *" 和其他变体）。但是现在，当 jBilling 启动时，我在日志中出现以下错误：

2013-10-28 16:28:26,215 调试 [com.sapienter.jbilling.server.pluggableTask.admin.PluggableTaskManager] 应用任务 com.sapienter.jbilling.server.MyPlugins.testLongTimeRunningPlugin 2013-10-28 16:28:26,217 调试[com.sapienter.jbilling.server.pluggableTask.admin.PluggableTaskManager] 创建 com.sapienter.jbilling.server.MyPlugins.testLongTimeRunningPlugin 的新实例 2013-10-28 16:28:26,225 WARN [com.sapienter.jbilling.server .util.Bootstrap] 无法安排可插入任务 [com.sapienter.jbilling.server.MyPlugins.testLongTimeRunningPlugin] 2013-10-28 16:28:26,225 调试 [com.sapienter.jbilling.server.util.Bootstrap] 启动作业调度器

所以我想知道为什么它不能被安排，我该如何解决它？这是代码：

public class testLongTimeRunningPlugin extends AbstractCronTask {
    public static final String taskName = testLongTimeRunningPlugin.class.getCanonicalName();
    private static final Logger LOG = Logger.getLogger(draftAPIgetProductCategories.class);
    private static final int time = 5;

    @Override
public String getTaskName() {
        return taskName;
    }

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        LOG.debug("Starting and waiting for " + time + " minutes");

        try{
            TimeUnit.MINUTES.sleep(time);
            LOG.debug("Completed");
        }catch (InterruptedException e){
            LOG.debug("Interrupted!");
        }
    }
}

Jbilling 可插入任务由 JBilling 系统本身处理，您不需要提供调度程序行为。您唯一需要做的就是在配置菜单中编写任务（自定义类）配置并将条目插入表中。

当您要创建Task时，您需要扩展/实现PlugableTask并需要在plugabletaskparameter表中指定类名，并具有适当的类别类型，例如：如果您要创建支付任务，则类别类型为6

在使用 5 参数 cron 表达式时，我们还遇到了“无法安排可插入任务”错误。更改为 6 参数表达式对我们有用，并允许安排任务。

例如，要安排每一分钟，我们将使用“0 * * * * ?” 而不是“0 * * * *”。
