spring的源代碼地址發(fā)生了更改，以前的地址是 https://src./svn/spring-framework/。但現(xiàn)在spring的代碼開始使用Git進行管理，新的源代碼地址為：https://github.com/SpringSource/spring-framework。

因為 GitHub 同樣支持svn的客戶端，因而仍然可以使用svn的命令進行代碼checkout。

附官方解釋：

The Spring Framework repository has moved to http://github.com/SpringSource/spring-framework.

See the readme there for details on working with Git, building the framework, etc.

Note that svn-based access is still available via GitHub's support for Subversion clients, e.g.:

    $ svn checkout https://github.com/SpringSource/spring-framework
