Use when generating JPA entities, repositories, queries, or anything touching the persistence layer. Covers entity conventions, N+1 prevention, projections, and query patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Spring Data JPA
## Entity Conventions
```java
@Entity
@Table(name = "orders")
@Getter
@NoArgsConstructor(access = AccessLevel.PROTECTED) // JPA requires no-arg, hide from callers
public class Order {
@Id
@GeneratedValue(strategy = GenerationType.UUID)
@Column(updatable = false, nullable = false)
private UUID id;
@Column(nullable = false)
private String customerEmail;
@Enumerated(EnumType.STRING) // always STRING, never ORDINAL
@Column(nullable = false)
private OrderStatus status;
@OneToMany(mappedBy = "order", cascade = CascadeType.ALL, orphanRemoval = true)
private List<OrderItem> items = new ArrayList<>();
@CreationTimestamp
@Column(updatable = false)
private Instant createdAt;
@UpdateTimestamp
private Instant updatedAt;
// Static factory, not public constructor
public static Order create(String customerEmail) {
Order order = new Order();
order.customerEmail = customerEmail;
order.status = OrderStatus.PENDING;
return order;
}
// Behavior on entity, not in service
public void addItem(Product product, int quantity) {

How to install
mdr add rrezartprebreza/spring-boot-skills/spring-data-jpa@sha256:870da57f793475b9The line at the top of this page pins the label git:20260704.22f1701, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
