Lazy loading inHibernate and JPAmeans fetching and loading the data, only when it is needed, from a persistent storage like a database. Lazy loading improves the performance of data fetching and significantly reduces the memory footprint. WhenHibernateinitializes the data object, actually it create...
This post will focus on why and how we use the concepts known as LAZY and EAGER loading in an application and how to use Spring’s hibernate template to load our LAZY entities in an EAGER fashion. And of course as the title itself suggests, we will show this by an example. The scenar...
