HibernateCursorItemReader with Hibernate Detached criteria

How to use hibernate detached criteria with "HibernateCursorItemReader" of spring batch?

Solution

  • A solution could be the following:

    1. create a custom HibernateDetachedCriteriaItemReader<> extends AbstractItemCountingItemStreamItemReader<>
    2. add a property Criteria criteria and inject it before use
    3. rewrite all do*() functions to manage resultset lifecycle

    Or extends from HibernateCursorItemReader and override doOpen() to let working in dual-mode (normal,with detached criteria)
