HIbernateCursorReader

See a normal usage sample as belows,

HibernateCursorItemReader itemReader = new HibernateCursorItemReader(); itemReader.setQueryString("from CustomerCredit"); //For simplicity sake, assume sessionFactory already obtained. itemReader.setSessionFactory(sessionFactory); itemReader.setUseStatelessSession(true); int counter = 0; ExecutionContext executionContext = new ExecutionContext(); itemReader.open(executionContext); Object customerCredit = new Object(); while(customerCredit != null){ customerCredit = itemReader.read(); counter++; } itemReader.close(executionContext);

 

Sample in Spring-Hibernate Context

HibernateCursorItemReader itemReader = new HibernateCursorItemReader(); itemReader.setSessionFactory( this.getSessionFactory() ); itemReader.setUseStatelessSession(true); String hql = "from cable where cable.cableid="+cableid; ExecutionContext executionContext = new ExecutionContext(); itemReader.open(executionContext); Cable cable = (Cable)itemReader.read(); return cable;

 

The executionContext and the SessionFactory must be set
