🕵🏿 👨🏽‍🌾 🗜️ 改札：HelloWorld 🤟🏼 🏒 🤰🏼

最近、素晴らしいWicketフレームワークの研究を始めました。残念ながら、RuNetにはこれに関する情報がほとんどないため、ここではその機能の一部を紹介します。そして、忘れないように書いてください。

Wicketは、Webアプリケーション用のユーザーインターフェイスを記述するためのフレームワークです。これにより、ほとんどのタスクをJavaで実装できます。すべての利点についての詳細は、オフサイトに記載されています。例はありますが、個人的にはあまり好きではありませんでしたので、興味のある人は「Wicket in action」という本（英語）に目を通すことをお勧めします（翻訳を完全に翻訳することはまずないでしょうが、そこからいくつかのグッズを紹介します）。そして今、ポイントに。プロジェクトを作成するには（私はmavenを使用しています）簡単な呪文を書きます

mvn archetype:create -DarchetypeGroupId=org.apache.wicket -DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=1.4.7 -DgroupId=ru.habrahabr.helowicket -DartifactId=helloworld

これによりプロジェクトが作成されます。その結果、3つのファイルを持つプロジェクトを取得します：WicketApplication.javaという名前のファイル、

HomePage.htmlファイルとHomePage.javaファイルには、それぞれページのレイアウトとロジックが含まれています（ファイルは同じ名前で、拡張子が異なる必要があります）。

HomePage.html

HomePage.java

意味ははっきりしていると思いますが、2語でコメントします。マークアップファイルには次の行が含まれています

おかげで、Javaコードでは、文字列を使用してこの要素にアクセスすることが可能になります

add(new Label("message", "If you see this message wicket is properly configured and running"));

その後、このオブジェクトを操作できます。つまり、属性（wicket：id）を介して、アプリケーションがサーバー側で実行されているときに作成されたオブジェクトとマークアップタグが比較されます。

add(new Label("message", new Date().toString()));

表示されないマークアップファイルからのメッセージ"message will be here"

注意してください。どのように機能するかは、お気に入りのIDEのマジックボタンをクリックすることで確認できます。たとえば、Eclipseでプロジェクトを開くには、 mvn eclipse:eclipse -DdownloadSources=true

を使用しmvn eclipse:eclipse -DdownloadSources=true

。プロジェクトディレクトリでmvn eclipse:eclipse -DdownloadSources=true

使用しmvn eclipse:eclipse -DdownloadSources=true

。スペルの完全なリストは、WicketのWebサイトにあります。
