其他人已经详细概述了OSGi的好处，我在此解释我所见过或使用过的实际用例。

In one of our application, we have event based flow and flow is defined in plugins based on OSGi platform so tomorrow if some client wants different/additional flow then he just have to deploy one more plugin, configure it from our console and he is done. It is used for deploying different Store connectors, for example, suppose we already have Oracle DB connector and tomorrow mongodb is required to be connected then write a new connector and deploy it and configure the details through console and again you are done. deployment of connnectors is handled by OSGi plugin framework.

它还被用于在移动端带来额外的中间件和应用程序的可移植性。移动端可用于WinMo, Symbian, Android等。一旦与设备功能集成，就会出现碎片化。

You can, analogically speaking, change the motor of your car without turning it off. You can customize complex systems for the customers. See the power of Eclipse. You can reuse entire components. Better than just objects. You use a stable platform to develop component based Applications. The benefits of this are huge. You can build Components with the black box concept. Other components don't need to know about hidden interfaces, them see just the published interfaces. You can use in the same system several equal components, but in different releases, without compromise the application. OSGi solves the Jar Hell problem. With OSGi you develop thinking to architect systems with CBD

对于使用Java的每个人来说，有很多好处(我现在只提醒了这些)。

我还不是OSGi的“粉丝”…

我一直在财富100强公司使用企业应用程序。最近，我们使用的产品已经“升级”为OSGi实现。

51分钟……每次代码改变…以前的版本(非osgi)在旧的开发机器上部署不到5分钟。

The "benefit" of this upgrade was sold as improving (production) deployments - an activity that we do about 4 times a year with maybe 2-4 small fix deployments a year. Adding 45 minutes per day to 15 people (QA and developers) I can't imagine ever being justified. In big enterprise applications, if your application is a core application, then changing it is, rightly so (small changes have potential for far reaching impacts - must be communicated and planned with consumers all over the enterprise), a monumental activity - wrong architecture for OSGi. If your application is not an enterprise application - i.e. each consumer can have their own tailored module likely hitting their own silo of data in their own silo'd database and running on a server that hosts many applications, then maybe look at OSGi. At least, that is my experience thus far.

至少，OSGi让您考虑到模块化、代码重用、版本控制以及项目的一般管道。
