SpringMVC + SpringセキュリティHibernate + Thymeleaf - 私のpom.xmlが多すぎますか？

Question

私のアプリケーションはJSPを使って最初に構築され、後の段階でThymeleaf + HTML5に切り替えました。しかし、私はpom.xmlを整理する時間をとっていません。

したがって、蛇紋岩の宣言依存性はあまりにも大きいですか？オーバーヘッドとパフォーマンスの問題が発生する可能性はありますか？

Answer 1

コードなしで完全にはわかりません。しかし、一見、私は一緒に

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-webmvc</artifactId> 
    <version>${springframework.version}</version> 
</dependency> 

と

<dependency> 
    <groupId>javax.ws.rs</groupId> 
    <artifactId>javax.ws.rs-api</artifactId> 
    <version>2.0.1</version> 
</dependency> 

を参照してください。あなたが書いたように、あなたのプロジェクトは "Spring MVC"なので、Spring APIを使って@Controllerと@RequestMappingを使ってRESTサービスを書くことができます。その結果、javax.wsライブラリを削除できます。これはJavaEE（@Path、 @GET、@ Consumerなど）、Jerseyや他の実装で使う方が良いです。しかし、必要はありません
