Vim，Java：在游标下打开类并转到方法

Vim can open a file under cursor using gf. For example, if I have the following under my cursor:

Vim可以使用gf在光标下打开一个文件。例如，如果我在光标下面有以下内容：

SensorManagementActivity.java

Hitting gf will open SensorManagementActivity.java.

点击gf将打开SensorManagementActivity.java。

The problem is that in Java, the references lack the java suffix, and often appear as SomeClass, SomeClass() or SomeClass.method().

问题是在Java中，引用缺少java后缀，并且通常显示为SomeClass，SomeClass（）或SomeClass.method（）。

How do I open SomeClass.java and jump to someMethod() when the cursor is on SomeClass.someMethod() in another file?
当光标位于另一个文件中的SomeClass.someMethod（）时，如何打开SomeClass.java并跳转到someMethod（）？
Is there a way to open a new file without saving the current one, and going back to the current one without losing changes?
有没有办法在不保存当前文件的情况下打开新文件，并在不丢失更改的情况下返回当前文件？

The 'suffixesadd' option allows gf to handle Java file extensions; it is already set by the java filetype that ships with Vim, like this:

'suffixesadd'选项允许gf处理Java文件扩展名;它已经由Vim附带的java文件类型设置，如下所示：

:setlocal suffixesadd=.java

To jump to methods, Vim can use a tags file that must be (re-)generated first (there are plugins that can automate that). For Java, you can use the exuberant ctags tool.

要跳转到方法，Vim可以使用必须首先（重新）生成的标记文件（有些插件可以自动生成）。对于Java，您可以使用繁琐的ctags工具。

:! ctags -R

For more information and alternatives, read :help ctags. Use the :tag command or the Ctrl-] shortcut to jump.

有关更多信息和替代方案，请阅读：help ctags。使用：tag命令或Ctrl-]快捷键进行跳转。

You can jump to a split window via Ctrl-W ]. To be able to leave a modified file and return back to it later, :set hidden in your ~/.vimrc.

您可以通过Ctrl-W跳转到拆分窗口。为了能够保留修改后的文件并稍后返回，请：在〜/ .vimrc中设置隐藏。
