An Apache ActiveMQ connection can be configured by explicitly setting properties on the ActiveMQConnection or ActiveMQConnectionFactory objects themselves via the bean properties or using the following URI syntax. Example You set the property called…

JAAS provides pluggable authentication, which means ActiveMQ will use the same authentication API regardless of the technique used to verify user credentials (a text file, a relational database, LDAP, and so on). All that’s required is an implementat…

先在官网下载activeMQ,我这里是5.10.0. 然后在解压在一个文件夹下即可. 我这里是:D:\apache-activemq-5.10.0-bin 然后进入bin目录:D:\apache-activemq-5.10.0-bin\apache-activemq-5.10.0\bin 可以看到有win32 与win64 你可以根据自己的需要启动mq. 我这里是win64,目录是:D:\apache-activemq-5.10.0-bin\apache-activemq-5.10.0\bin\…

If none of any built-in security mechanisms works for you, you can always build your own. Though these features should provide enough functionality for the majority of users, an even more powerful feature is available. As stated previously, the Activ…

The easiest way to secure the broker is through the use of authentication credentials placed directly in the broker’s XML configuration file. Such functionality is provided by the simple authentication plug-in that’s part of ActiveMQ. The following l…

方法一 通过 ActiveMQ Web 控制台删除. 方法二 通过 Java 代码删除. ActiveMQConnection.destroyDestination(ActiveMQDestination destination) 方法三 通过配置 conf/activemq.xml, 当 broker 探测到闲置的队列或主题,删除.回收资源. <broker xmlns="http://activemq.apache.org/schema/core" brokerName=&q…

When messages expire on the ActiveMQ broker (they exceed their time-to-live, if set) or can’t be redelivered, they’re moved to a dead-letter queue, so they can be consumed or browsed by an administrator at a later point. Messages are redelivered to a…

To build upon authentication, consider a use case requiring more fine-grained control over clients to authorize certain tasks. ActiveMQ provides two levels of authorization: operation-level authorization and message-level authorization. These two typ…

In this section we’ll look at two useful features of ActiveMQ: subscribing to multiple destinations using wildcards, and publishing to multiple destinations using composite destinations. ActiveMQ uses a special notation to denote a wildcard subscript…

问题导读1.borker包含哪些属性?2.Producer包含哪些属性?3.Consumer如何配置?borker(0.9.0及0.10.0)配置Kafka日志本身是由多个日志段组成(log segment).一个日志是一个FileMessageSet,它包含了日志数据以及OffsetIndex对象,该对象使用位移来读取日志数据 * borker配置就是指配置server.properties文件 *最小配置通常情况下需要在减压缩kafka后,修改config/server.properties…

转自:http://www.cnblogs.com/f1194361820/p/6048429.html 通过前面的架构简述,知道了Producer是用来产生消息记录,并将消息以异步的方式发送给指定的topic的某个partition的.另外还知道,它保证了消息的有序的发送.那么它是如何做到这些的呢?我们又该如何使用它的API来发送消息? Kafka Producer.Kafka Consumer相对于 Kafka Broker,都属于客户端.Kafka支持多种语言的客户端.下面就根据Java…

对于NGINX 支持epoll模型 epoll模型的优点 定义: epoll是Linux内核为处理大批句柄而作改进的poll,是Linux下多路复用IO接口select/poll的增强版本,它能显著的减少程序在大量并发连接中只有少量活跃的情况下的系统CPU利用率.因为它会复用文件描述符集合来传递结果而不是迫使开发者每次等待事件之前都必须重新准备要被侦听的文件描述符集合,另一个原因就是获取事件的时候,它无须遍历整个被侦听的描述符集,只要遍历那些被内核IO事件异步唤醒而加入Ready队列的描述符集合…

Mono是Xamarin资助的一个项目,是微软的.NET框架的开源实现.它使得使用C#.F#和其他.NET语言进行跨平台开发成为可能.Xamarin在Mono之上构建了跨平台开发工具以及像Xamarin.Forms(可以使用跨平台代码辅助创建原生的体验)这样的框架产品.开发工具和框架在开发者之间都有应用(Xamarin最近获得了5400万美元C轮融资,会继续在这方面发力).Xamarin也已经在和微软开展合作,以改进.NET和Mono之间的兼容性.ASP.NET vNext(尤其是KRuntim…
