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…

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…

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…

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…

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…

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…

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…
