Spring教程：隐藏在Eclipse Mars中的包浏览器视图中的文件夹

Question

我正在关注Spring使用REST API教程：http://spring.io/guides/gs/rest-service/

在git cloning gs-rest-service / initial项目之后，我将此项目作为Spring Tool Suite中的现有项目导入。

但是在Package Explorer视图中，我没有看到src / main中的任何文件夹，但是在硬盘驱动器中，当我尝试创建新文件夹时，我确实看到了这些文件夹：java/hello再次。如何使这些文件夹出现在Eclipse的Package Explorer边栏中？

你的包裹是空的吗？

您是否刷新了工作区？

检查您的Java元素过滤器＆＃39;你没有空包裹＃39;检查了吗？

Package Explorer is a virtual view of your project, so what you're seeing is that virtual representation has "relocated" Java sources to a virtual folder in that view. Package Explorer represents source locations (such as src/main/java) as a package container instead of an ordinary folder. Look at the first node under the project; it has a different icon and is labeled src/main/java - that's where the source files are presented.

If you want a more literal file-system view, open the Navigator view. Also look at Project Explorer, which shows both the literal view and the "virtual" view that Package Explorer shows.
