Since Spring Security is an Open Source project, we’d strongly encourage you to check out the source code using git. This will give you full access to all the sample applications and you can build the most up to date version of the project easily. Having the source for a project is also a huge help in debugging.
由于Spring Security是一个开源项目，我们强烈建议您使用git查看源代码。这将使您可以完全访问所有示例应用程序，并且可以轻松地构建项目的最新版本。拥有项目的源代码也是调试的巨大帮助。
Exception stack traces are no longer obscure black-box issues but you can get straight to the line that’s causing the problem and work out what’s happening. The source is the ultimate documentation for a project and often the simplest place to find out how something actually works.
异常堆栈跟踪不再是模糊的黑盒问题，但您可以直接找到引起问题的线路并找出正在发生的事情。源代码是项目的最终文档，通常是查找实际工作方式的最简单的地方。
To obtain the source for the project, use the following git command:
要获取项目的源，请使用以下git命令：
git clone https://github.com/spring-projects/spring-security.git
This will give you access to the entire project history (including all releases and branches) on your local machine.
这将使您可以访问本地计算机上的整个项目历史记录（包括所有版本和分支）。
