当只有一个工作,没有别的并行.当我将JobRepository的隔离级别更改为ISOLATION_READ_COMMITTED时,异常消失.

这个例外的原因是什么？

The default isolation level for that method is SERIALIZABLE,which is
quite aggressive: READ_COMMITTED would work just as well;
READ_UNCOMMITTED would be fine if two processes are not likely to
collide in this way. However,since a call to the create* method is
quite short,it is unlikely that the SERIALIZED will cause problems,as long as the database platform supports it.
