I am pleased to announce that the spring-kafka (Spring for Apache Kafka) Second Milestone for version 1.0 is now available.

The artifacts org.springframework.kafka:spring-kafka:1.0.0.M2 and org.springframework.kafka:spring-kafka-test:1.0.0.M2 are available in the Milestone repository.

Changes since the First Milestone include:

• KafkaTemplate.send() methods now return ListenableFuture<SendResult<K, V>>

to track publishing to the Kafka topic asynchronously.

• The MessagingMessageListenerAdapter (for @KafkaListener method) can now infer the type for payload conversion from the method arguments.
• A StringJsonMessageConverter, which can use the type inference to build the target object from JSON content using the Jackson ObjectMapper.
• RECEIVED_ headers have been added from the Listener to avoid clashing (re-routing) to the same topic with the same messageKey when sending, e.g. with the Spring Integration Adapters.
• More testing utilities.

On behalf of the team, I am pleased to announce the release of Spring Cloud Stream 1.0.0.RC2, available here. As part of the release candidate cycle, it comes with a number of bug fixes and a small number adjustments. The complete list of changes is available here.

Some highlights:

• Spring Cloud Stream applications now use the ObjectMapper provided by Spring Boot, if available;
• Header embedding is now a general purpose producer/consumer property. It can be enabled or disabled by middlewares that require embedding for header propagation. This allows easier interoperability outside Spring Cloud Stream; (until now it was a Kafka-specific property);
• Further documentation and sample improvements.

Dear Spring community,

It is my pleasure to announce that a feature-complete Spring Framework 4.3 release candidate is available now! This is a perfect opportunity for you to get involved: Please run your regression tests against it, and of course, feel free to try the new features...

Dependency injection refinements:

* @Autowired injection of Map/Collection beans and self references * @Autowired on configuration class constructors (finally!) * No need for declaring @Autowired on a unique non-default constructor * ObjectProvider as a richer variant of an ObjectFactory handle * InjectionPoint/DependencyDescriptor as an injectable argument for @Bean methods

MVC processing refinements:

* Default processing of OPTIONS, HEAD, Allow and If-Unmodified-Since * Support for custom HTTP Vary configuration and HTTP Range on custom resources * Precomposed @GetMapping, @PostMapping, @RequestScope, @SessionScope etc * @RequestAttribute and @SessionAttribute as handler method arguments * Full support for Jackson 2.7's new type resolution algorithm

Various infrastructural refinements across the framework:

* Wider support for composed annotations and for placeholders/expressions in attributes * Richer programmatic metadata in core container exceptions * Component scanning in manifest-defined classpath entries * A background initialization option for bootstrapping JPA / Hibernate * A 'sync' flag on @Cacheable and support for the Caffeine cache provider

We are working towards an RC2 with some remaining fine-tuning and performance improvements in the meantime, preparing for 4.3's general availability on June 1st!

Cheers, Juergen

We are pleased to announce the second milestone of Spring AMQP 1.6 is available.

Additions since the first milestone include:

• The caching connection factory now exposes cache statistics

• @RabbitListener methods now communicate type information to the message converter for inbound messages. This means, for example, the Jackson2JsonMessageConverter no longer needs a custom class mapper when a message without type information in the headers is received (e.g. from a sender that is not a Spring AMQP app). Instead, the @RabbitListener method parameter type is used in the conversion. In addition, the Method and bean are also made available via message properties to custom converters.
