Now more and more Java developers are talking about OSGi in a way that makes sense. When I went to school a few years ago, I did a lot of Eclipse plug-in development, and then I personally felt that the Eclipse plug-in system is flexible and powerful, and the system and OSGi are also feather. Recently intend to re-examine the system of OSGi, while learning to wri

1, the introduction of OSGi:OSGi is an abbreviation for Open Service Gateway initiative, a dynamic model system for Java. The OSGi service platform provides services to Java, which makes Java a preferred environment for software integration and software development, and is described in more detail on the encyclopedia:Http://baike.baidu.com/link?url=jZjzRuQzq7R_3i5Itkykb80ecbAC_ Ygfx-zpsrcu43zmsa13bmzgc86fydvxqe3csoeplphub2aicvx-cgnonpkkpqe9jctveqecocz

Publishing and using Services Since the OSGi framework can easily hide implementation classes, it is natural to provide interfaces externally, and the OSGi Framework provides registration and query capabilities for services. OK, so let's actually do it on the basis of Hello World project. (If not please refer to previous article: OSGi notes (i) HelloWorld) We nee

To use OSGi Annotation in Bundle, you must first define two BeanPostProcessor. We have read the previous article. Here we will take a look at it, as shown in: (figure 1) the above two beans are inherited to org. springframework. beans. factory. config. instantiationAwareBeanPostProcessorAdapter aims to execute additional operations for each Bean in the context of Spring instantiation. Here we want to intercept whether each Bean initialized in Spring c

After installing Apache Felix, the following is how to develop my first bundle. The entire process is a referenceApache Felix Tutorial example 1-service event listener bundle. Open a DOS window and switch to the directory where the bundle is to be stored.D: \ develop \ eclipse-jee-indigo-SR2-win32 \ workspace \ Felix-AnalysisFor example. Create an empty project using Maven. MVN archetype: Create-dgroupid = Felix. Tutorial-dartifactid = example1-dpackagename = Felix. Tutorial. example1-dve

Now it's all in the HelloWorld. To cover all three levels of the OSGi framework, this HelloWorld may be a little more complicated than the other OSGi HelloWorld programs you see. If you're unfamiliar with some of the APIs in your code, remember to go back to the previous entry to find the corresponding content, which will help you understand the code. The key code inside has been highlighted in yellow. (For

What's 1.1 Equinox? From a code standpoint, Equinox is actually a complete implementation of the OSGi core standard, and adds some additional functionality on this basis (such as adding a command line and a program execution entry for the framework). All of the things we've been explaining in the previous introductory article are a small part of the OSGi core standard. In fact, its core is a jar package, wh
