JMS的替代品有哪些? [英] What are the alternatives of JMS?

问题描述

对于JMS，我们还有其他选择吗?

Do we have any alternative for JMS?

问题陈述 我们有一个名为Configuration Manager的组件，其中包含应用程序的配置.该配置管理器由该应用程序的4个实例使用.现在，每当管理员更改配置时，都应将其通知应用程序的所有实例.

Problem statement We have a component called Configuration Manager, which contains configuration of the application. This configuration manager is used by 4 instances of the application. Now , any time an administrator changes the configuration, it should get notified to all the instances of the application.

推荐答案

即使在更新后，您的问题仍然不清楚.根据您提供的信息，我看到两个选择:

Even after your update, your question is still not crystal clear. Given the information you provided, I see two options:

• 通知.确实使用JMS或其他通知机制.这取决于技术堆栈:是Web应用程序吗?桌面应用程序?它可以在应用服务器中运行吗?
• 轮询.每个应用程序都有一个后台线程，该线程轮询配置管理器(或数据库?)以查找更改.检测到更改后，将重新加载整个配置.

• notification. Use indeed JMS or some other notification mechanism. That depends on the technology stack: is it web applications? desktop application? does it run in an application server?
• polling. Each application has a background thread that polls the configuration manager (or the database?) for changes. When changes are detected, the whole configuration is reloaded.

对于配置刷新的问题，我宁愿进行轮询(至少这是我们用于类似要求的方法，并且效果很好).

For the problem of configuration refresh, I would rather go for polling (at least that's what we used for a similar requirement and it worked fine).
