本demo实现的是一个简单的登陆功能。

# 1、开发环境 #

MyEclipse 10+JDK1.6+Tomact7+Struts 2.3.28.1+Spring 2.0.8+Hibernate 3.2.0

# 2、准备工作 #

新建一个web项目，并下载相应的jar包。

引入的所有jar包：

![Center][]

注：如果出现包冲突现象，留下高版本。

# 3、搭建Struts2 #

1）引入jar包：asm-3.3.jar

commons-fileupload-1.3.1.jar

commons-io-2.2.jar

commons-lang3-3.2.jar

freemarker-2.3.22.jar

javassist-3.11.0.GA.jar

log4j-api-2.3.jar

ognl-3.0.14.jar

struts2-core-2.3.28.1.jar

xword-core-2.3.28.1.jar

2）在Web.xml中配置struts2：

<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>

3） 从struts2压缩包中拷贝出一个struts.xml文件放置src目录下。

<?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" />
 	
 	
 	<constant name="struts.action.extension" value="action" />
 	
 	
 	<constant name="struts.ui.theme" value="simple" />
 	
 	 
 	<constant name="struts.objectFactory" value="spring" /> 
 	
 	
 
 	
 	
 	<package name="struts2" extends="struts-default">
 
 		
 		
 
 		
 		
 		<action name="login" class="loginAction">
 			<result name="success">/main.jsp</result>
 			<result name="input">/login.jsp</result>
 		</action>
 	</package>
 </struts>

# 4、 搭建Spring #

1）引入的jar包：spring.jar

log4j-1.2.14.jar

commons-logging.jar

2）在src下建立application.xml文件

<?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:aop="http://www.springframework.org/schema/aop"
 	xmlns:tx="http://www.springframework.org/schema/tx"
 	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
 
 	
 
 	
 	
 	
 	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 		<property name="configLocation" value="classpath:hibernate.cfg.xml"/>
 	</bean>
 
 	
 	
 	 <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 	 	<property name="sessionFactory" ref="sessionFactory"/>
 	 </bean>
 
 	
 	
 	<tx:advice id="smAdvice" transaction-manager="transactionManager">
 		<tx:attributes>
 			<tx:method name="save*" propagation="REQUIRED" />
 			<tx:method name="del*" propagation="REQUIRED" />
 			<tx:method name="update*" propagation="REQUIRED" />
 		</tx:attributes>
 	</tx:advice>
 
 	
 	
 	
 	
 	<bean id="userDao" class="com.jmj.hibernate.UserDaoImpl" scope="singleton">
 		
 		<property name="sessionFactory" ref="sessionFactory" />
 	</bean>
 
 	
 	<bean id="userManager" class="com.jmj.spring.UserManagerImpl">
 		<property name="userDao" ref="userDao" />
 	</bean>
 
 	
 	
 	
 	<bean id="loginAction" class="com.jmj.struts2.LoginAction" scope="prototype">
 		<property name="userManager" ref="userManager" />
 	</bean>
 	
 	
 </beans>

3）在web.xml中添加对application.xml文件的引用

<context-param>
 		<param-name>contextConfigLocation</param-name>
 		<param-value>classpath:applicationContext.xml</param-value>
 	</context-param>

# 5、搭建Hibernate #

1）引入的jar包：Hibernate3.jar

dom4j-1.6.1.jar

commons-logging-1.0.4.jar

commons-collections-2.1.1.jar

cglib-nodep-2.2.3.jar

jta.jar

asm.jar

antlr-2.7.6.jar：hibernate执行hql语句

2）在src目录下，建立hibernate.cfg.xml文件，配置数据库连接和hibernate与数据库对象的关系映射文件。

<!DOCTYPE hibernate-configuration PUBLIC
 	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 	"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
 
 <hibernate-configuration>
 	
 	<session-factory>
 		<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
 		
 		<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/s2sh_user</property>
 		<property name="hibernate.connection.username">用户名</property>
 		<property name="hibernate.connection.password">密码</property>
 		
 		<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
 		
 		<property name="hibernate.show_sql">true</property>
 		
 		<property name="hibernate.format_sql">true</property>
 		
 		 
 
 
 
 
 		
 		<mapping resource="/com/jmj/domain/User.hbm.xml"/>
 		
 		
 	</session-factory>
 </hibernate-configuration>

3）建立对象关系映射文件：User.hbm.xml

<?xml version="1.0"?>
 <!DOCTYPE hibernate-mapping PUBLIC 
 	"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 	"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
 	
 <hibernate-mapping>
 	<class name="com.jmj.domain.User" table="t_user">
 		<id name="id" >
 			<generator class="uuid"></generator>
 		</id>
 		<property name="username"/>
 		<property name="password"></property>
 	</class>
 </hibernate-mapping>

# 6、整合S2SH框架 #

1）引入的jar包：struts2-spring-plugin-2.3.28.1.jar  -----struts2和spring整合的jar包

mysql-connector-jar-3.1.13-bin.jar：mysql数据库驱动

2）在web.xml文件中，加入监听

<listener>
 		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 	</listener>

3）其他部分的代码详解

UserDaoImpl.java：

/** 
 * @Title: UserDaoImpl.java
 * @Package com.jmj.hibernate
 * @Description: TODO
 * @author meng
 * @date 2016-5-17 下午7:46:27

 		if (null==list|| list.isEmpty())
 		{
 			return false;
 		}
 		
 		return true;
 		//删除、添加、更新用户
 		/*this.getHibernateTemplate().delete(user) 
 		save(user)

 	}
 
 }

 		if(this.userDao.findUserByUserName(username,password))
 		{
 			return true;
 		}
 		
 		return false;
 	}
 
 }

/**

 		}
 		if (user.getPassword()==null||user.getPassword().length()==0)

 public class User
 {

 	private String username;
 	
 	private String password;
 
 	public String getId()
 	{
 		return id;

 	public String getPassword()
 	{
 		return password;
 	}
 
 	public void setPassword(
 			String password)
 	{
 		this.password = password;
 	}
 	
 }

JSP页面：

main.jsp

欢迎【<s:property value="user.username"/>】登陆！

# 知识拓展： #

在action 里面定义要接收的参数，并提供相应的setter,getter，则Jsp页面可以直接使用此属性名；而在action中引用model层的模型，保存其对象，则jsp页面中需要使用“对象.属性名”。
