Struts Spring Hibernate統合の例

投稿日: 2019-11-05 2019-11-05
タグ: Hibernate, integration, Spring, struts

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。

struts-spring-hibernate-1、title = "struts-spring-hibernate-1"

struts-spring-hibernate-2、title = "struts-spring-hibernate-2"

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。

4.休止状態

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。

Customer.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

5.春

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。

データベースの詳細を宣言し、 ”

LocalSessionFactoryBean

“を介してSpringとHibernateを統合します。

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。

AddCustomerAction.java **

package com.mkyong.customer.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.beanutils.BeanUtils;

public ActionForward execute(ActionMapping mapping,ActionForm form,
    HttpServletRequest request,HttpServletResponse response)
        throws Exception {

    CustomerBo customerBo =
      (CustomerBo) getWebApplicationContext().getBean("customerBo");

    CustomerForm customerForm = (CustomerForm)form;
    Customer customer = new Customer();

   //copy customerform to model
    BeanUtils.copyProperties(customer, customerForm);

   //save it
    customerBo.addCustomer(customer);

    return mapping.findForward("success");

  }
}

    HttpServletRequest request,HttpServletResponse response)
        throws Exception {

    CustomerBo customerBo =
      (CustomerBo) getWebApplicationContext().getBean("customerBo");

    DynaActionForm dynaCustomerListForm = (DynaActionForm)form;

    List<Customer> list = customerBo.findAllCustomer();

    dynaCustomerListForm.set("customerList", list);

    return mapping.findForward("success");

  }

import org.apache.struts.action.ActionMessage;

public class CustomerForm extends ActionForm {

    private String name;
    private String address;

   //getter and setter, basic validation

}

Customer.properties **

#customer module label message
customer.label.name = Name
customer.label.address = Address

customer.label.button.submit = Submit
customer.label.button.reset = Reset

#customer module error message
customer.err.name.required = Name is required
