Introducing Spring Framework 5.3
summary
Spring Framework 5.3 finalizes the 5.x line with concrete deliverables: constructor/record-style data binding and a DataClassRowMapper; a core reactive transaction manager and a new Spring R2DBC module with r2dbc GA and a DatabaseClient (WebClient-style) for reactive SQL; JdbcTemplate gains a closeable Stream API and a JDBCTransactionManager that translates commit-time exceptions; performance work (hashmap pre-sizing, array-deque swaps, lock-free caches); native-image flags to drop XML/SpEL for smaller builds and early support for GraalVM-native images while targeting JDK 17 LTS (RC mid‑Sept, GA end‑Oct).
