保存和恢复更改

介绍

When working with IntelliJ IDEA, you don't need to worry about saving changed files: all changes are auto saved.

Unwanted changes can be undone at any stage of you development workflow. Any file or directory can be reverted to any of the previous states.

什么时候IntelliJ IDEA会自动保存文件？

Autosave is initiated by:

• Compiling a project, a module or a class
• Starting a run/debug configuration
• Performing a version control operation such as pull, commit, push, etc.
• Closing a project
• Quitting the IDE

In fact, there is a lot more autosave triggers, and only the most important ones are mentioned above.

关闭自动保存行为

The following options are available for tuning the autosave behavior(File | Settings | Appearance and Behavior | System Settings)

以一个不同的文件名保存文件

There is no File | Save As command in IntelliJ IDEA. To save a file under a different name or in a different directory, use Refactor | Copy or F5.

恢复更改

You can undo changes by using Edit | Undo 或 ⌘Z。 To revert files to their previous states , use Local History and corresponding version control functionality.
