We now use Flux.usingWhen() instead materialize/dematerialize operators
to reuse Reactor's resource closure.
Until usingWhen() accepts a BiFunction to consume error signals,
we need to map error signals outside of usingWhen which requires
re-wrapping of the ReactiveTransaction object.
Such a static unmodifiable TransactionDefinition with defaults can be used for getTransaction(null) calls, now also possible for getReactiveTransaction. Furthermore, it can be used for a simple TransactionalOperator.create(ReactiveTransactionManager) method without an internal dependency on the transaction.support package.
See gh-22646
Introduces TransactionManager marker interface for PlatformTransactionManager as well as ReactiveTransactionManager, allowing for a common configuration type in TransactionAspectSupport and TransactionManagementConfigurer.
Closes gh-22590
Introduces TransactionExecution base interface for TransactionStatus as well as ReactiveTransaction. Renames getTransaction method to getReactiveTransaction, allowing for combined implementations of PlatformTransactionManager and ReactiveTransactionManager.
See gh-22646
This commit adds SPI interfaces to support reactive transactions
through spring-tx with optional dependencies to Project Reactor and
supportive implementations for TransactionalOperator and
AbstractReactiveTransactionManager.
Prior to this when SpEL compiled an expression using the numeric
operators <, >, <= or >= then it would not create code that handled
nulls. Nulls can occur if a boxed numeric operand is used prior
to compilation, then it is nulled out. SpEL now creates null
handling bytecode.
Closes gh-22358
This commit deprecates MediaType.APPLICATION_JSON_UTF8 and
MediaType.APPLICATION_PROBLEM_JSON_UTF8 in favor of
MediaType.APPLICATION_JSON and MediaType.APPLICATION_PROBLEM_JSON since
UTF-8 encoding is now handled correctly by most browsers
(related bug has been fixed in Chrome since September 2017).
MediaType.APPLICATION_JSON is now used as the default JSON content type.
Closes gh-22788
