Web application development based on spring DM

The biggest feature of the Spring DM 1.1.x is that it can support the deployment of Web applications in which it is a cool feature and I even feel that developing an OSGi Web application in this way is better than using the spring DM server, At least for now you can get better portability (which can run on multiple OSGI platforms supported by the spring DM), and the spring DM server does not provide more enterprise application support.

But for those of you who just used the spring DM for Web application development, it's not easy to configure successfully. The following detailed explanation of the relevant configuration.

1 bundles required to run the environment:

These bundles can be found in the Spring DM 1.1.2 Release package, where the start level of the above bundles is set to 2.

2 Add log4j Log configuration Bundles

The purpose of this bundles is to provide log4j.properties, and the detailed approach can refer to my "Spring OSGi QuickStart"

3 Developing Web applications

Web applications are developed in much the same way as a typical web, just adding some osgi configurations.

The approximate structure is as follows:

META-INF
　　 MANIFEST.MF
　　 WEB-INF
　　 Classes
　　 Lib
　　 Web.xml
　　 applicationContext.xml
