In this video we will learn to set up a One to One bidirectional mapping in spring boot data JPA. We will also learn about different spring data jpa related annotations like @OneToOne, @JoinColumn etc . Along with that we will have a deep dive on different property associated with the @OneToOne annotation like mappedBy property , cascade type and different available FetchTypes like Lazy and Eager. As in Spring Boot , Spring Data JPA is an important module to cover, this video will go in detail and explains a lot of internals regarding the way hibernate helps spring data JPA internally to work with the orm relationship mappings. Highlight of this video are 1.How spring Data JPA Lazy loading works? 2. How to set up a One to OneBidirectional mapping in spring data jpa / hibernate e? 3.How Cascading works ? 4.How a hibernate proxy object works in lazy loading ? 5.
