Ask Henrik something hard.
Spring Boot service: APM shows one endpoint firing 300+ SQL queries per request. Hibernate. You already know what it is, right?
CLAUDE · AS HENRIK, JAVA 開發人員
N+1, yes - but the fix is not sprinkling EAGER, which just moves the explosion to every other endpoint. Turn on hibernate.generate_statistics and assert query counts in tests; for this endpoint: JOIN FETCH or an EntityGraph for the associations it renders, or a DTO projection if it's read-only - most 300-query endpoints are lists needing 4 columns, not entities. Pin the count in a test (expect 2-3, not 300) so the regression can't sneak back, and check open-in-view - if it's on, your fixed endpoint still lazy-loads during serialization. Paste the entity graph and I'll write the fetch plan.

Henrik 的工作內容
Henrik 會將 Claude（或 ChatGPT，或任何 AI 聊天工具）轉變為資深 Java/Spring Boot 後端工程師，根據實際證據診斷 N+1 查詢、交易邊界錯誤、REST API 設計與 Spring Security 設定問題，然後提供具體且可立即執行的計畫。
適用對象
正在執行正式環境 Spring Boot 服務的後端工程師與創辦人，需要正確處理架構、JPA/Hibernate 效能、交易或安全性決策。
主要功能
- 應用程式架構：根據實際領域複雜度，而非流行趨勢，在分層式架構與六角形架構之間做出選擇
- JPA/Hibernate 效能：偵測 N+1 查詢、JOIN FETCH、@EntityGraph 與批次抓取，並以實際查詢次數為依據
- 交易管理：根據實際工作單位，決定 @Transactional 的配置位置與傳播行為（REQUIRED、REQUIRES_NEW、NESTED）
- REST API 設計：資源命名、狀態碼、版本控制與分頁方式，符合 API 的實際使用方式
- Spring Security：根據實際威脅模型，配置篩選器鏈、JWT 與工作階段驗證的選擇，以及方法層級授權
- 測試策略：在實際資料庫確實重要的地方，使用 JUnit/Mockito 單元測試、Spring 切片測試與 Testcontainers 整合測試
使用方式
下載技能檔案，並將完整內容貼入 Claude 專案指示（或任何 AI 聊天工具的系統 prompt）中。接著以日常語言描述你的問題，即可取得具體且可立即執行的計畫 - 不必每次工作階段重新解釋背景。適用於 Claude、ChatGPT 與任何 AI 聊天工具。安裝時間不到 2 分鐘。

關於此產品的問題
What AI tools does this work with?+
Claude, ChatGPT, or any AI chat that accepts a system prompt or Project Instructions. Claude Projects gives the best results.
How do I install it?+
Paste the SKILL.md contents into your Claude Project Instructions or system prompt. Under 2 minutes, no setup required.
Is this a course or a tool?+
It's a single skill file, not a course. Load it once and Henrik applies the same expertise and methodology from the first message of every session.
Can Henrik fix an endpoint making hundreds of queries?+
Yes. Share the endpoint and entity relationships and Henrik diagnoses the exact N+1 pattern and the exact fetch-strategy fix (JOIN FETCH, entity graph, or projection) with the expected query-count reduction.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
Ready to specialise your AI?
One drop-in file. Pay once, keep forever - works with Claude & ChatGPT.
