Heim >häufiges Problem >So formatieren Sie Code in der Idee
Ideale Methode zum Formatieren des Codes: 1. Verwenden Sie direkt die Tastenkombination „Strg+Alt+L“, um den Code zu formatieren. 2. Öffnen Sie die Idee, klicken Sie auf „Datei“ – „Einstellungen“ – „Plugins“, suchen und installieren Sie „Eclipse Code Formatter“ und importieren Sie dann die Konfigurationsdatei „Eclipse-Codestyle.xml“. +Alt" +L" Formatcode.
Die Betriebsumgebung dieses Tutorials: Windows10-System, IDEA2020.1.3, Dell G3-Computer.
IDEA, der vollständige Name von IntelliJ IDEA, ist eine integrierte Entwicklungsumgebung für die Programmiersprache Java. IntelliJ gilt als das beste Java-Entwicklungstool der Branche, insbesondere in Bezug auf intelligente Code-Assistenten, automatische Code-Eingabeaufforderungen, Refactoring, JavaEE-Unterstützung, verschiedene Versionstools (Git, SVN usw.), JUnit, CVS-Integration, Code-Analyse und innovatives The Funktionen im GUI-Design und anderen Aspekten können als außergewöhnlich bezeichnet werden. IDEA ist ein Produkt von JetBrains, einem Unternehmen mit Hauptsitz in Prag, der Hauptstadt der Tschechischen Republik. Seine Entwickler sind hauptsächlich osteuropäische Programmierer, die für ihre Genauigkeit bekannt sind. Die Flaggschiffversion unterstützt auch HTML, CSS, PHP, MySQL, Python usw. Die kostenlose Version unterstützt nur wenige Sprachen wie Java und Kotlin.
Methode 1: Native Methode
In IDEA können Sie den Code mit der Tastenkombination Strg+Alt+L formatieren.
Verwenden Sie die Tastenkombinationen Strg+Alt+L, um den Code zu formatieren, und das Codeformat wird ordentlich.
Methode 2: Plug-Ins verwenden
Haben Sie jemals eine Situation erlebt, in der sich der Code nach Verwendung der Tastenkombination „Strg+Alt+L“ kaum ändert und das formatierte Ergebnis nicht das erreicht? erwarteter Effekt? Sie können auch die Formatierungsvorlage für den Konfigurationscode ausprobieren. 1. Konfigurationsschritte für Ideenformatierungsvorlagen
Öffnen Sie den Ideeneditor:Datei->Einstellungen->Plugins
, suchen Sie nach Eclipse Code Formatter
. Dies ist eine Seite, die installiert wurde
2. Importieren Sie die Konfigurationsdateieclipse-codestyle.xml
Nach Abschluss der oben genannten Schritte schließen Sie die Seite nicht und suchen Sie den folgenden Andere Einstellungen-> ;Adapter-Eclipse-Codeformatierer
-Pfad, suchen Sie den Speicherort, an dem die Datei eclipse-codestyle.xml
entsprechend dem Bildspeicherort gespeichert ist, und fügen Sie sie einfach hinzu ( Fügen Sie die Datei am Ende des Artikels ein
)
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
)
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
eclipse-codestyle.xml
2. Formatieren des Codes formatiert nur den von mir geänderten Code und nicht den unveränderten Code.
eclipse-codestyle.xml
