Use when you need to write or review programmatic JDBC with Spring — including JdbcClient (Spring Framework 7+) as the default API, JdbcTemplate only where batch/streaming APIs require JdbcOperations, NamedParameterJdbcTemplate for legacy named-param code, parameterized SQL, RowMapper mapping to records, batch operations, transactions, safe handling of generated keys, DataAccessException handling, read-only transactions, streaming large result sets, and @JdbcTest slice testing. This should…
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 JDBC — JdbcClient (Spring Framework 7+) Apply Spring JDBC guidelines with JdbcClient as the default; use JdbcTemplate / NamedParameterJdbcTemplate only for legacy code or APIs not covered by JdbcClient (batch updates, KeyHolder, RowCallbackHandler streaming). **What is covered in this Skill?** - Parameterized SQL (never concatenate user input) - JdbcClient fluent API (Spring Framework 7+) — preferred for queries and updates - Named parameters via JdbcClient; NamedParameterJdbcTemplate for legacy migration - RowMapper, query(Class), and records - Batch operations and generated keys (JdbcTemplate / JdbcOperations where needed) - Safe handling of generated keys (KeyHolder; single-row JdbcClient updates) - Service-layer @Transactional boundaries - Read-only transactions (@Transactional(readOnly = true)) - Safe single-row access (optional() / findFirst() vs queryForObject) - Streaming large result sets (RowCallbackHandler, ResultSetExtractor) - DataAccessException handling (DuplicateKeyException, EmptyResultDataAccessException) - @JdbcTest slice testing with @Sql fixtures **Scope:** Apply recommendations based on the reference rules and good/bad code examples. …

How to install
mdr add jabrena/plinth/311-frameworks-spring-jdbc@sha256:3e6fccf470c082dbThe line at the top of this page pins the label v0.19.0, 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.
