数据库中有100条数据，在一个配置文件里面，配置了10个定时任务，但是走的job类是同 一个，在启动项目的时候，如何确保这同时跑的10个定时任务，不重复读取一条数据或者重复读取相同的几条数据，防止修改一条数据的时候，别的定时任务已经执行完成，这就造成了数据库重复添加数据； （加锁是不可能得因为造成死锁。）
配置文件如下

可以用数据库悲观锁，取10条没处理过的数据，select * from table where status=0 for update，取出10条同时锁住这10条
其实不建议启10个timer，应该是启一个timer，取出数据后分配线程来处理。
另外，用注解启timer了解一下，比写xml优雅点
个人见解：数据库对应记录加锁，或者采用中间件将数据进行缓存处理一下，比如通过阻塞队列，进行处理。
100条数据，10个定时任务跑对吧，你10个定时任务就是10个对象。
你把100 条数据划分为10块，每块10条数据（可以以Id划分。1-10；11-20。。。。）不行么？
