Jpa Patterns

Covers the classic JPA pain points you'll eventually hit in any Spring Boot app: N+1 queries killing performance, LazyInitializationException blowing up outside transactions, and the EAGER vs LAZY debate. The quick reference table maps symptoms to fixes, which is handy when you're staring at Hibernate logs. Heavy focus on JOIN FETCH, EntityGraph, and DTO projections as practical solutions. Also walks through transaction propagation, which matters more than people think when you're dealing with nested service calls. The examples are realistic, showing both the broken patterns and working alternatives. If you're debugging why your app suddenly fires 500 queries on a simple list endpoint, this will save you time.
