idea格式化代码的方法：1、直接使用快捷键“Ctrl+Alt+L”格式化代码。2、打开打开idea，依次点击“File”-“Settings”-“Plugins”，搜索并安装“eclipse code formatter”；然后导入配置文件“eclipse-codestyle.xml”；最后使用快捷键“Ctrl+Shift+Alt+L”格式化代码。

本教程操作环境：windows10系统、IDEA2020.1.3、Dell G3电脑。

IDEA 全称 IntelliJ IDEA，是java编程语言的集成开发环境。IntelliJ在业界被公认为最好的Java开发工具，尤其在智能代码助手、代码自动提示、重构、JavaEE支持、各类版本工具(git、svn等)、JUnit、CVS整合、代码分析、 创新的GUI设计等方面的功能可以说是超常的。IDEA是JetBrains公司的产品，这家公司总部位于捷克共和国的首都布拉格，开发人员以严谨著称的东欧程序员为主。它的旗舰版还支持HTML，CSS，PHP，MySQL，Python等。免费版只支持Java,Kotlin等少数语言。

idea格式化代码的方法

方法1：原生方法

在IDEA中，可以使用Ctrl+Alt+L快捷键格式化代码。

使用Ctrl+Alt+L快捷键格式化代码，这时代码格式会变得很工整。

方法2：利用插件

是否遇到过使用快捷键“Ctrl+Alt+L”后代码几乎没变化，格式化后的结果没有达到预期效果，不妨试试配置代码格式化模板。

一、idea格式化模板配置步骤

1、安装插件：EclipseCodeFormatter

阿里配置文件只是针对eclipse，所以导入配置文件之前需要先安装EclipseFormatter插件

打开idea编辑器：File->Settings->Plugins，搜索 eclipse code formatter。

我这是已经安装好的页面

2、导入配置文件 eclipse-codestyle.xml

上面步骤操作完页面不要关，找到下面的Other Settings->Adapter eclipse code formatter路径，按照图片位置找到eclipse-codestyle.xml文件保存的位置，添加进去就行了（文件放文章后面）

二、格式化代码只格式化我修改的代码不格式化未修改的代码

只格式化自己写的代码，不格式化版本仓库里面的代码，防止代码评审或者代码对比出现大量不一致的代码
快捷键：Ctrl+Shift+Alt+L

idea怎麼格式化程式碼

  • 在默认情况下，Scope 选项是 Whole file ，也就是格式化当前窗口的全部代码
  • Only changes uncommitted to VCS表示只格式化我修改的，不格式化我未修改的代码
  • 我们也可以设置在自动保存的时候触发代码格式化。 操作方法：File->Settings->Tools->Actions on Save 中进行设置。
    注意在勾选完Reformat code 之后后面的 Whole file 这里要改为 Changed lines
