Many case asking that “Spring JPA lazy loading not working!”. So it is very hard to start with Hibernate and Spring JPA. In the tutorial, I will help you understand SpringJPA Hibernate Lazy Fetch Type and Eager Fetch Type by example code with Spring Boot & MySql database using with Spring JPA annotations’ @onetoone
and @onetomany
– Lazy Loading is a design pattern which is used to defer initialization of an object as long as it’s possible. The FetchType.LAZY
tells Hibernate to only fetch the related entities from the database when you use the relationship
(This does not load the relationships unless you invoke it via the getter method)
– Eager Loading is a design pattern in which data initialization occurs on the spot. Eager initialization takes more memory consumption and processing speed is slow. FetchType.EAGER
= This loads all the relationships.
