Spring Framework 开源j2ee框架
Spring是什么呢？首先它是一个开源的项目，而且目前非常活跃；它是一个基于IOC和AOP的构架多层j2ee系统的框架，但它不强迫你必须在每一层 中必须使用Spring，因为它模块化的很好，允许你根据自己的需要选择使用它的某一个模块；它实现了很优雅的MVC，对不同的数据访问技术提供了统一的接口，采用IOC使得可以很容易的实现bean的装配，提供了简洁的AOP并据此实现Transcation Managment，等等
Spring for Apache Kafka 1.0 Candidate 1 发布了，以下是本次发布值得关注的内容：
A ConsumerRebalanceListener can be injected into the MessageListenerContainer;
The KafkaConsumer and KafkaProducer can be customized with (De)Serializer s for key and value in the ConsumerFactory and ProducerFactory, respectively; this is an alternative to configuring using the properties.
JsonSerializer and JsonDeserializer s are provided, based on the Jackson library;
A RecordFilterStrategy and the FilteringMessageListenerAdapter are provided to allow skipping records or dealing with duplicate deliveries;
A self-explanatory RetryingMessageListenerAdapter is provided;
A ListenerContainerIdleEvent is emitted, after a configurable time, when the MessageListenerContainer has moved to an idle state;
TopicPartitionInitialOffset is provided to allow configuring the MessageListenerContainer to be assigned to specific partitions in the topic(s) and, optionally, seek to the desired offset when starting;
The @KafkaListener 's @TopicPartition attribute is enhanced with the @PartitionOffset property for initial offset configuration;
Improvements for consumer rebalance events.
