Eclipse: Can you format code on save?
提问by Fostah
In Eclipse, under Windows-> Preference-> Java-> Code Style, you can define code templates for comments and code, and you can setup a code formatter.
在 Eclipse 中，在Windows-> Preference-> Java-> 下Code Style，您可以为注释和代码定义代码模板，并且可以设置代码格式化程序。
I'm wondering if it is possible in Eclipse to have these setting take affect every time I save a source file. Basically, instead of me highlighting everything and pressing Ctrl+Shift+F, I want Eclipse to be responsible for making sure my code is formatted properly.
我想知道是否有可能在 Eclipse 中每次保存源文件时使这些设置生效。基本上，我不是突出显示所有内容并按Ctrl+ Shift+ F，而是希望 Eclipse 负责确保我的代码格式正确。
Is this possible and how do you set it up?
这是可能的，你如何设置它？
Note On Using the Auto-Format:It's probably best to choose "Format Edited Lines" as merging changes becomes very difficult when you reformat a whole file that is in source control already that was not formatted properly. Already did this to a co-worker.
使用自动格式的注意事项：最好选择“格式化编辑行”，因为当您重新格式化已在源代码管理中且格式不正确的整个文件时，合并更改变得非常困难。已经对同事这样做了。

Under Preferences, choose Java--> Editor--> Save Actions. Check the Perform the selected actions on save, and check the Format source codebox.
在 下Preferences，选择Java--> Editor--> Save Actions。选中Perform the selected actions on save，然后选中Format source code复选框。
This may or may not be available in previous versions of Eclipse. I know it works in:
这在早期版本的 Eclipse 中可能可用，也可能不可用。我知道它适用于：
Version: 3.3.3.r33x_r20080129-_19UEl7Ezk_gXF1kouft<br>
Build id: M20080221-1800

I strongly recommend checking your eclipse format xml descriptor into source control. That way all members of the team can use it and you don't get to and fro reformatting battles.
我强烈建议将您的 eclipse 格式 xml 描述符检查到源代码管理中。这样，团队的所有成员都可以使用它，而您不必来回重新格式化战斗。

I have a snapshot of the setting. Please follow the path:
我有一个设置的快照。请遵循以下路径：
In the Preferenceswindow, choose Java--> Editor--> Save Actions.
在Preferences窗口中，选择Java--> Editor--> Save Actions。
Check the Perform the selected actions on save, and check the Format source code box.
检查Perform the selected actions on save，然后检查Format source code box。

If you find that you do not have a Save Actionspreference under Java--> Editor, it may be because you are using an older version of Eclipse. In that case you can install the Format on save plugin from here.
如果您发现Save Actions在Java-->下没有首选项Editor，可能是因为您使用的是旧版本的 Eclipse。在这种情况下，您可以从此处安装 Format on save 插件。
Then, under Preferences, choose Java--> Format on save. Select the Run Formatoption under Select a code formatting action
然后，在 下Preferences，选择Java--> Format on save。选择下面的Run Format选项Select a code formatting action
