Apache ActiveMQ 5.7.0 發布，Java開源消息中間件

今天 Apache ActiveMQ 5.7.0發布，這次發布的主要目的是兼容Java 7兼容。 該項目雖然使用JDK 6構建，但經測試在Java 7上正常工作。由于ActiveMQ現在使用 Camel 2.10，所以需要增加對Java 7的支持。

除此之外，還增加兩個特性并修復關閉了200多個Bug。新特性：

• 安全 WebSocket (wss) 傳輸 – 這意味著，現在可以從瀏覽器直接安全地連到broker。詳細信息請查看here
  
• Broker 重新傳遞 – which allows you to define redelivery policy such that broker will resend a message to a different consumer in case that processing fails. Here you can find more information on when you’d want to use this feature and how.
  

我們也提高了我們的存儲鎖定機制，所以現在是完全可插拔的（completely pluggable.）This means that locking is not tied to the store itself, but it’s separately configured. And also you can tune it or implement new locking strategies to suit your environment. We also provided a new database locker, called Lease Database Locker, which should do much better job for JDBC master slave scenarios.

ActiveMQ 是最流行的，能力強勁的開源消息總線。ActiveMQ 是一個完全支持JMS1.1和J2EE 1.4規范的 JMS Provider實現
