このStruts 1.x Spring Hibernateの例をダウンロードする –

Struts-Spring-Hibernate-Example.zip

このチュートリアルでは、簡単な顧客管理（追加と選択）Webアプリケーション、プロジェクト管理ツールとしてのMaven、WebフレームワークとしてのStruts 1.x、依存性注入フレームワークとしてのSpring、データベースORMフレームワークとしてのHibernateの作成方法を学びます。

全体的な統合アーキテクチャは次のようになります。

Struts (Web page) <---> Spring DI <--> Hibernate (DAO) <---> Database

それらの技術をすべて統合するには、あなたは..

SpringとHibernateを統合する

”

LocalSessionFactoryBean

“クラス。

Springの準備ができたStrutsプラグインを使用してSpringとStrutsを統合する –

”

ContextLoaderPlugIn

“。

1.プロジェクトの構成

これが最終的なプロジェクト構造です。

2.テーブルスクリプト

顧客の詳細を格納する顧客テーブルを作成します。

DROP TABLE IF EXISTS `mkyong`.`customer`;
CREATE TABLE  `mkyong`.`customer` (
  `CUSTOMER__ID` bigint(20) unsigned NOT NULL AUTO__INCREMENT,
  `NAME` varchar(45) NOT NULL,
  `ADDRESS` varchar(255) NOT NULL,
  `CREATED__DATE` datetime NOT NULL,
  PRIMARY KEY (`CUSTOMER__ID`)
) ENGINE=InnoDB AUTO__INCREMENT=10 DEFAULT CHARSET=utf8;

3. Mavenの詳細

すべてのStruts、Spring、およびHibernateの依存ライブラリをpom.xmlに定義します。

Hibernateで設定する必要はほとんどありません。顧客のXMLマッピングファイルとモデルを宣言するだけです。

ビジネスオブジェクト（BO）とデータアクセスオブジェクト（DAO）のSpringのBean宣言。 DAOクラス（CustomerDaoImpl.java）はSpringの「

HibernateDaoSupport

」クラスを拡張し、Hibernate関数に簡単にアクセスします。

7.ストラットスプリング

StrutsとSpringを統合するには、struts-config.xmlファイルにSpringのbuild-in Strutsプラグイン「

ContextLoaderPlugIn

」を登録する必要があります。 Actionクラスでは、Springの ”

ActionSupport

“クラスを拡張する必要があり、

getWebApplicationContext（）

を介してSpring Beanを取得できます。
