Class BeanIOStreamFactory

java.lang.Object
  org.beanio.spring.BeanIOStreamFactory

All Implemented Interfaces:

FactoryBean

public class BeanIOStreamFactory
extends Object
implements FactoryBean

A Spring factory bean for creating shared StreamFactory instances for BeanIO item readers and writers. Using a shared StreamFactory can improve performance by preventing mapping files from being loaded more than once when multiple item readers and writers are repeatedly invoked or share the same mapping configuration.
