注释

关于XML配置中元素的具体信息可以参考

/ 下面介绍本篇配

置使用的一些重要元素。

DispathPolicy

ActiveMQ支持3中不同的分发策略（避免翻译了以后误解，这里用原文）：

1. ：Simple dispatch policy that sends a

message to every subscription that matches the message.

2. ：Simple dispatch policy that sends a message

to every subscription that matches the message.

3. ：Dispatch policy that causes every

subscription to see messages in the same order.

SubscriptionRecoveryPolicy

ActiveMQ支持6种恢复策略，可以自行选择使用不同的策略

1. ： keep a fixed count of

last messages.

2. ： keep a fixed amount of

memory available in RAM for message history which is evicted in time

order.

3. ：only keep the last message.

4. ：disable recovery of messages.

5. ：perform a user specific

query mechanism to load any messages they may have missed.

6. ：keep a timed buffer of messages

around in memory and use that to recover new subscriptions.
