JPA/Hibernate Patterns

Use for data modeling, repositories, and performance tuning in Spring Boot.

When to Activate

• Designing JPA entities and table mappings
• Defining relationships (@OneToMany, @ManyToOne, @ManyToMany)
• Optimizing queries (N+1 prevention, fetch strategies, projections)
• Configuring transactions, auditing, or soft deletes
• Setting up pagination, sorting, or custom repository methods
• Tuning connection pooling (HikariCP) or second-level caching

Entity Design

@Entity
@Table(name = "markets", indexes = {
  @Index(name = "idx_markets_slug", columnList = "slug", unique = true)
})
@EntityListeners(AuditingEntityListener.class)
public class MarketEntity {
  @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long id;

  
   String name;

  
   String slug;

  
      MarketStatus.ACTIVE;

    Instant createdAt;
    Instant updatedAt;
}
