我正在使用Eclipse Juno和Java 1.7,我已经创建了一个测试项目.现在问题出在项目浏览器上.如果类有任何错误,Project explorer不会显示编译错误.我清理,关闭并重建项目但没有任何改变.它仍然没有在项目浏览器中显示错误.它与Helios一起工作正常.

在SpringBoot微服务中,我试图为每个mean_of_payment_id选择一个actor的最新记录.为此,请使用mean_of_payment_id上的group by子句为actor_id选择actor内容,其中created_date等于max(created_date)嵌套查询的子集.我正在使用JPQL.下面是表结构和查询.

    @Query("select ac from ActorContent ac "
        + "where (ac.actor.uuid=:actorUuid ) and "
        + "ac.createdDate IN ( SELECT MAX(aci.createdDate) "
            + "FROM ActorContent aci WHERE ac.actor.uuid=aci.actor.uuid "
            + "and aci.uuid = ac.uuid group by ac.meanOfPayment.id)"
        )

不幸的是,在执行查询后,我得到了所有记录,但我期待的是前三行.MeanOfPayment和Actor是ActorContent的引用表.

我有一个shell脚本在crontab其中执行jar文件.Jar文件正在将文件从一台服务器移动到另一台服 在高峰时段,它需要超过10分钟(更多的crontab条目).

如何cron在最后一个工作完成之前确保作业不会执行？
