java - Web 片段项目和动态 Web 项目有什么区别？

Question

Eclipse 上的 Web 片段项目和动态 Web 项目有什么区别？您会推荐使用哪一个来构建干净的结构网站？

Answer 1

IBM defines Web Fragment如下:

A web fragment is a logical partitioning of the web application in such a way that the frameworks being used within the web application can define all the artifacts without requiring you to edit or add information in the web.xml.

此外:

A web fragment is a mechanism for either defining or extending the deployment descriptor of a web application by means of pluggable library jars that contain both the incremental deployment information (in the web-fragment.xml) and potentially any related or relevant classes. The web fragment is also packaged as a library (jar), with the web-fragment.xml in the META-INF directory. Consequently, the web fragment project is essentially a Utility project, with the addition of a web fragment facet to it. The web fragment facet enables you to add relevant context-sensitive functionality to the fragment project.

本质上，Web 片段(在 Servlet 3.x 中引入)允许您创建部署描述符 web.xml 的可重用部分(或片段)。

因此，如果您想创建一个完整的动态 Web 应用程序，请在 Eclipse 中创建一个“动态 Web 项目”。本质上，您需要应用程序服务器/容器的 web.xml 来部署您的应用程序，“动态 Web 项目”有助于实现此方法。

希望对您有所帮助。
