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 1.1 GA 发布了,与先前的 Milestone 2 相比没有太多的变化,下面是更新内容:
Apache Kafka 0.10
upgrade;
The batch of messages support via BatchMessageListener
as well as via@KafkaListener
annotation configuration;
The null payload
concept support via KafkaNull
placeholder object;
You can now perform seek operations from the listener - this allows setting an initial offset when partitions are assigned by Kafka when using group management. You can also perform arbitrary seek operations after initialization;
Allow setting the initial offset to be relative to the current offset;
The KafkaTemplate
now provides access to the metrics
and partitionsFor
methods on the Producer
.
