搭建Struts2.3.16，Hibernate4.3.1和Spring4.0.2环境

1 下载包

hibernate: http://hibernate.org/orm/downloads/

struts2： http://struts.apache.org/download.cgi

spring4： http://maven.springframework.org/release/org/springframework/spring/4.0.2.RELEASE/

2 新建空Web Project

3 复制struts2常用包到WebRoot/WEB-INF/lib下

4 修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

在WEB-INF下新建jsp文件夹，用来保存jsp文件，也可以直接放在WebRoot下。放在WEB-INF下的好处是只有服务端可以访问。
/jsp/Login.jsp：

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
    <head>
        <title>Login</title>
    </head>

    <body>
        <s:form action="Auth" method="POST">
            <s:textfield key="name"/>
            <s:password key="pwd" />
            <s:submit/>
        </s:form>
    </body>
</html>

/jsp/Welcome.jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
    <head>
        <title>Welcome</title>
    </head>

    <body>
    <h2>Welcome!</h2>
        name: ${name} <br />
        pwd: ${pwd}
    </body>
</html>

5 在src目录下新建struts.xml文件

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <package name="default" namespace="/" extends="struts-default">
    
        <action name="Login" class="com.test.struts2.DemoAction" method="login">
            <result>/WEB-INF/jsp/Login.jsp</result>
        </action>
        <action name="Auth" class="com.test.struts2.DemoAction" method="auth">
            <result>/WEB-INF/jsp/Welcome.jsp</result>
        </action>
    </package>
</struts>

在src下新建DemoAction.java

package com.test.struts2;

import com.opensymphony.xwork2.ActionSupport;

public class DemoAction extends ActionSupport {
    
    private String name;
    private String pwd;
    
    public String execute() {
        return SUCCESS;
    }
    
    public String login() {
        return SUCCESS;
    }
    
    public String auth() {
        return SUCCESS;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }
    
}

现在的工程结构图：

struts就搭好了。访问http://localhost:8081/demo/Login查看结果。

暂时没有做登录验证。只是显示输入的用户名和密码。

4 复制hibernate常用包到/WebRoot/WEB-INF/lib下

先把lib/required下面的包复制到lib中，然后下载mysql-connector-java-5.1.7-bin.jar 这个包加入。可能会下载到不同的版本，都无所谓。

新建Account类：

package com.test.model;

public class Account {
    private Long id;
    private String name;
    private String pwd;

    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;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

}

新建Account类和数据库表的映射文件Account.hbm.xml：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.test.model">

    <class name="Account" table="Account">
        <id name="id" column="Account_ID">
            <generator class="increment"/>
        </id>
        <property name="name" column="name"/>
        <property name="pwd" column="pwd"/>
    </class>

</hibernate-mapping>

在本地MySQL或者其他数据库新建数据库demo。新建hibernate配置文件：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>

        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/demo</property>
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>
        <property name="connection.pool_size">5</property>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <property name="hbm2ddl.auto">create</property>
        <property name="current_session_context_class">thread</property>

        <mapping resource="com/test/model/Account.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

根据自己的实际情况填写。现在只要本地可以连接数据库就OK了。新建IDao接口：

package com.test.dao.impl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

import com.test.dao.IDao;


public class IDaoImpl<T> implements IDao<T> {

    private static final SessionFactory sessionFactory;
    
    static {
        try {
             sessionFactory = new Configuration()
                 .configure().buildSessionFactory();
        } catch (Throwable ex) {
            throw new ExceptionInInitializerError(ex);
        }
    }
    
    @Override
    public T get(String hql) {
        Session session = sessionFactory.openSession();
        try {
            session.beginTransaction();
            List list = session.createQuery(hql).list();
            if (list != null && list.size() > 0)
                return (T) list.get(0);
            return null;
        } finally { 
            session.getTransaction().commit();
            session.close();
        }
    }

}

现在Hibernate已经和struts整合完成。实现了用户登录数据库验证。

5 搭建Spring环境

导入libs/下的*RELEASE.jar文件就可以了。下载commons-dbcp-1.4.jar，commons-pool-1.6.jar包。这两个包跟数据连接池有关。
为了实现Service层和dao层的分离，新建Service层。

Iservice.java:

package com.test.service;

public interface IService<T> {
    
    public T get(String hql); 
}

IServiceImpl.java

package com.test.service.impl;

import com.test.dao.IDao;
import com.test.service.IService;

public class IServiceImpl<T> implements IService<T> {
    
    private IDao<T> dao;
    
    public IDao<T> getDao() {
        return dao;
    }

    public void setDao(IDao<T> dao) {
        this.dao = dao;
    }

    @Override
    public T get(String hql) {
        // TODO Auto-generated method stub
        return dao.get(hql);
    }
    
}

为了使用spring，新建applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p" 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/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/tx  
    http://www.springframework.org/schema/tx/spring-tx.xsd">


    <!-- 数据源配置 -->

        destroy-method="close">

        <property name="url" value="jdbc:mysql://localhost:3306/demo" />
        <property name="username" value="root" />
        <property name="password" value="root" />
        <property name="initialSize" value="5" />
        <property name="maxActive" value="500" />
    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
        destroy-method="destroy">
        <property name="dataSource" ref="dataSource" />
        <property name="mappingResources">
            <list>
                <value>com/test/model/Account.hbm.xml</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>
    </bean>

    <bean id="dao" class="com.test.dao.impl.IDaoImpl">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <!-- 在Service层配置事务 -->
    <bean id="hibernateTransactionManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
        <!-- <property name="dataSource" ref="dataSource" /> -->
    </bean>

    <bean id="hibernateTransactionAttributeSource"
        class="org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource">
        <property name="properties">
            <props>
                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>

    <bean id="service"
        class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager" ref="hibernateTransactionManager" />
        <property name="target">
            <bean class="com.test.service.impl.IServiceImpl">
                <property name="dao" ref="dao" />
            </bean>
        </property>
        <property name="transactionAttributeSource" 
            ref="hibernateTransactionAttributeSource" />
    </bean>
    
    <!-- spring生成action -->
    <bean id="demoAction" scope="prototype" class="com.test.struts2.DemoAction">
        <property name="service" ref="service" />
    </bean>

</beans>

现在Hibernate.cfg.xml已经没用了，删掉这个文件。为了struts和spring结合，加入struts2-spring-plugin-2.3.16.jar包。

web.xml

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
    
    <constant name="struts.devMode" value="true" />

            <result>/WEB-INF/jsp/Welcome.jsp</result>
            <result name="error">/WEB-INF/jsp/error.jsp</result>
        </action>
    </package>
</struts>

DemoAction.java

package com.test.struts2;

import com.opensymphony.xwork2.ActionSupport;
import com.test.model.Account;
import com.test.service.IService;

public class DemoAction extends ActionSupport {
    
    private IService service;
    
    private String name;
    private String pwd;
    
    public String execute() {
        return SUCCESS;
    }
    
    public String login() {
        return SUCCESS;
    }
    
    public String auth() {
        String hql = "from Account where name='" + name + "' and pwd='" + pwd + "'";
        Account account = (Account) service.get(hql);
        return account == null ? "error" : SUCCESS;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

    public IService getService() {
        return service;
    }

    public void setService(IService service) {
        this.service = service;
    }
    
}

现在ssh整合基本上完成了。还有一些没有描述的包可以在源码里面查看。
