项目目的：
整合使用最新版本的三大框架（即Struts2、Spring4和Hibernate4）搭建项目架构原型。
项目架构原型：Struts2 + Spring4.0+ Hibernate4.2.4。
项目特色：同时使用了Struts2、Spring4、Hibernate4、log4j等库或框架，搭建一个最基本的项目原型。

加入 Spring

• 加入Spring 所需 jar 包

  

• 配置 web.xml 文件

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">

    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:applicationContext*.xmlparam-value>
    context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>


web-app>

• 加入 Spring 的配置文件[ applicationContext.xml ]

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

加入Hibernate

• 加入Hibernate所需jar包

• 加入 hibernate.cfg.xml 文件, 在其中配置 hibernate 的基本属性

<hibernate-configuration>
    <session-factory>
        

        
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialectproperty>

        
        <property name="hibernate.show_sql">trueproperty>
        <property name="hibernate.format_sql">trueproperty>

        
        <property name="hibernate.hbm2ddl.auto">updateproperty>

        
        
    session-factory>

hibernate-configuration>

• 和 Spring 进行整合

加入 c3p0 和 MySQL 的驱动

新建db.properties

jdbc.user=root
jdbc.password=1230
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8

jdbc.initPoolSize=5
jdbc.maxPoolSize=10

在 Spring 的配置文件中配置: 数据源, SessionFactory, 声明式事务

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">


    <context:annotation-config />
    <context:component-scan base-package="com" />

    
    <context:property-placeholder location="classpath:db.properties"/>

    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="user" value="${jdbc.user}">property>
        <property name="password" value="${jdbc.password}">property>
        <property name="driverClass" value="${jdbc.driverClass}">property>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}">property>

        <property name="initialPoolSize" value="${jdbc.initPoolSize}">property>
        <property name="maxPoolSize" value="${jdbc.maxPoolSize}">property>
    bean>

    
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource">property>
        <property name="configLocation" value="classpath:hibernate.cfg.xml">property>
        <property name="mappingLocations" value="classpath:com/entities/*.hbm.xml">property>
    bean>

    
    
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory">property>
    bean>

    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="lastNameIsValid" read-only="true"/>
            <tx:method name="*"/>
        tx:attributes>
    tx:advice>

    
    <aop:config>
        <aop:pointcut expression="execution(* com.service.*.*(..))" id="txPointcut"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
    aop:config>

• 小测试

新建实体类Test.java

package com.entities;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "test")
public class Test {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;//主键
    private String name;


    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

}

hibernate.cfg.xml 添加

   <session-factory>
        
        <mapping class="com.entities.Test">mapping>
    session-factory>

如果成功，数据库内自动生成Test表

加入 Struts2

• 加入 jar 包: 若有重复的 jar 包, 则需要删除版本较低的.

  

• 在 web.xml 文件中配置 Struts2 的 Filter

    
    <filter>
        <filter-name>struts2filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilterfilter-class>
    filter>

    <filter-mapping>
        <filter-name>struts2filter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

• 加入 Struts2 的配置文件，新建struts.xml

<struts>

    <package name="default" namespace="/" extends="struts-default">

            <action name="test">
                <result>index.jspresult>
            action>   

    package>

struts>

• 测试 在浏览器输入http://localhost:8080/S2S4H4/test 若无异常，整个框架搭建完毕
