3.4 Summary
3.4 小结
This brief introduction to the book examples is meant to be just that—quick and
focused. The jobs and portfolio use cases are common in the business world, but
they’re only two use cases of many available for using messaging. Although these two
use cases are meant to demonstrate the two JMS messaging domains at a high level,
that doesn’t mean that they can’t do more. Using the features available in ActiveMQ,
these two examples will be changed and adapted as the book progresses. So you’ll see
much more of these examples throughout the chapters, just with slight variations.
Part 1 of the book took you through an introduction to ActiveMQ, where you
gained a quick high-level understanding of ActiveMQ. Then the focus shifted to
understanding message-oriented middleware and the JMS spec. Although these topics
aren’t strictly about only ActiveMQ, each is important when it comes to understanding
ActiveMQ. You also walked through the examples that will be used throughout the rest
of the book. The subjects in this first part of the book are meant to be a warm-up for
diving deeper into ActiveMQ. In part 2, you’ll learn about configuring various aspects
of ActiveMQ for connectivity, message persistence, and security.
本章专注于对本书中实例的快速与简要介绍.job和portfolio这两个例子在现实世界中是非常常见的,
但是它们也仅仅是许许多多可以使用消息机制的各种场景中的两个用例.尽管这两个例子旨在概述JMS
的两种消息机制,但是这两个例子可以做的还有很多.在阅读本书过程中,这两个例子将不断的被修改
以便说明ActiveMQ的各种特性.你将在后面的章节中重复看到对这两个例子做了轻微修改后的版本.
本书第一部分展示了ActiveMQ的概况.接下来本书将关注面向消息的中间件以及JMS规范.尽管这些专题不仅仅
是针对ActiveMQ的,但是每一个专题都对了解ActiveMQ至关重要.至此,你也通览了将贯穿本书的两个实例.
本书第一部分是深入了解ActiveMQ的一个热身.接下来本书第二部分中,你将学习如何进行ActiveMQ的连接配置,
消息持久化配置以及安全配置.
