show-sql writes to System.out, Hibernate’s bind logging prints every value in clear, an OpenTelemetry collector cannot erase what it receives, and a file appender quietly sets a one-year retention. The leaks no code review sees, and how to own the one switch you deliberately keep.
A logging rule that lives in a wiki holds only where its author was looking. How we turned it into a JUnit test that scans every module’s sources, why it must prove it scanned something, and why we why we decided against runtime log masking.
A record’s toString(), an exception message your global handler logs, an e-mail as the actor: the three leaks that put personal data into almost every Spring API’s logs, and what to write instead.
Why paging over a non-unique sort key returns duplicated or missing rows, and a reusable way to append a unique tie-breaker to every Spring Data sort.
How we send application events to Elasticsearch from Spring Boot through a buffer table and a scheduled, cluster-safe job, so an Elasticsearch outage never fails a business transaction.
A practical springdoc-openapi setup, shown twice where it differs: once for Spring Boot 2.7 (springdoc 1.x, javax) and once for Spring Boot 3 and 4 (springdoc 2.x / 3.x, jakarta).
