常见实现类有ArrayBlockingQueue、LinkedBlockingQueue、PriorityBlockingQueue,、SynchronousQueue等。 6、ArrayBlockingQueue 与 LinkedBlockingQueue 的区别 队列中锁的实现不同,ArrayBlockingQueue实现的队列中的锁是没有分离的,即生产和消费用的是同一个锁;LinkedBlockingQueue实现的队列中的锁是分离的,即生产用的是putLoc...

The Message Queue installation includes example programs illustrating both JMS and JAXM messaging (see Chapter 5, Working with SOAP Messages). They are located in the following directories:Installation from IPS image: IMQ_HOME/examples Installation from Solaris SVR4 packages: /usr/demo/imq ...
This section includes and describes two code samples: one that sends a JMS message with a SOAP payload, and another that receives the JMS/SOAP message and processes the SOAP message.Example 5–5 illustrates the use of the JMS API, the SAAJ API, and the JAF API to send a SOAP message ...
For example, here is a class that applies first-in-first-out tie-breaking to comparable elements. To use it, you would insert a new FIFOEntry(anEntry) instead of a plain entry object.{@code class FIFOEntry<E extends Comparable<? super E>> implements Compara...
Java基于内存的消息队列实现 有需要源码的同学可以去Gitee上下载: https://gitee.com/hyxl-520/memory_message_queue 先看测试情况 需求背景 需求来源于我写的一个单体应用方便使用的动态任务调度框架(详细内容见Gitee地址:https://gite
status - The status of the queue. Returns: Returns a reference to this object so that method calls can be chained together. See Also: QueueStatus getTags public Map<String,String> getTags() The tags used to organize, track, or control access for this resource. For example, { "Tags": ...
