spring-data-jpa SKILL.md skillA

spring-data-jpa from giuseppe-trisciuoglio/developer-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add giuseppe-trisciuoglio/developer-kit/spring-data-jpa@git:20260324.a02e282

Pins git:20260324.a02e282 in mdr.lock. Pin the fingerprint instead.

Provides patterns to implement persistence layers with Spring Data JPA. Use when creating repositories, configuring entity relationships, writing queries (derived and `@Query`), setting up pagination, database auditing, transactions, UUID primary keys, multiple databases, and database indexing.

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.

What the file says

# Spring Data JPA

## Overview

Provides patterns for Spring Data JPA repositories, entity relationships, queries, pagination, auditing, and transactions.

## When to Use

Creating repositories with CRUD operations, entity relationships, `@Query` annotations, pagination, auditing, or UUID primary keys.

## Instructions

### Create Repository Interfaces

To implement a repository interface:

1. **Extend the appropriate repository interface:**
   ```java
   @Repository
   public interface UserRepository extends JpaRepository<User, Long> {
       // Custom methods defined here
   }
   ```

2. **Use derived queries for simple conditions:**
   ```java
   Optional<User> findByEmail(String email);
   List<User> findByStatusOrderByCreatedDateDesc(String status);
   ```

3. **Implement custom queries with `@`Query:**
   ```java
   @Query("SELECT u FROM User u WHERE u.status = :status")
   List<User> findActiveUsers(@Param("status") String status);
   ```

### Configure Entities

1. **Define entities with proper annotations:**
   ```java
   @Entity
   @Table(name = "users")
   public class User {
       @Id
       @GeneratedValue(strategy = GenerationType.IDENTITY)
       private Long id;
…

How to install

The exact contents, by fingerprint

mdr add giuseppe-trisciuoglio/developer-kit/spring-data-jpa@sha256:2bb11e952eb7ac06

The line at the top of this page pins the label git:20260324.a02e282, 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.
