spring-boot-configuration

spring-boot-configuration is a cursor rule for Cursor from claire-gong-18/awesome-cursorrules. It costs 188 tokens per session, scanned A, a copy of spring-boot-configuration, CC0-1.0.

Architecture rules for Java Spring Boot 3 applications using Maven, Java 17, PostgreSQL, and related Spring libraries. They assign request handling, business logic, database access, and data transfer to separate layers.

In plain words
What is it for?
Use them when structuring Spring Boot applications with REST controllers, service implementations, repositories, entities, and DTOs.
Why use it?
They prevent controllers, services, and database code from becoming tightly mixed together. DTOs keep internal database entities from being exposed directly through the API.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

spring-boot-configuration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to spring-boot-configuration — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

  • Framework: Java Spring Boot 3 Maven with Java 17 Dependencies: Spring Web, Spring Data JPA, Thymeleaf, Lombok, PostgreSQL driver
  • All request and response handling must be done only in RestController.
  • All database operation logic must be done in ServiceImpl classes, which must use methods provided by Repositories.
  • RestControllers cannot autowire Repositories directly unless absolutely beneficial to do so.
  • ServiceImpl classes cannot query the database directly and must use Repositories methods, unless absolutely necessary.
  • Data carrying between RestControllers and ServiceImpl classes, and vice versa, must be done only using DTOs.
  • Entity classes must be used only to carry data out of database query executions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
