需要的jar包，包含了spring mvc的jar

<!-- 统一管理 jar 包版本 -->

数据库连接资源文件：jdbc.properties

hibernate.dialect=org.hibernate.dialect.MySQLDialect

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/springmvc
jdbc.username=root
jdbc.password=root

数据库连接配置 applicationDataSource.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

	<bean id="springmvcDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

	</bean>
	
	<bean id="jdbcSpringmvcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" p:dataSource-ref="springmvcDataSource" />
 	
</beans>

将applicationDataSource.xml 加入的web.xm中

<!-- 设定配置文件列表 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			 <!-- classpath*: 指定编译后的class目录  -->
			classpath*:config/application*.xml
		</param-value>
	</context-param>

model类的编写：

package com.longxia.springmvc.model;

import java.util.Date;

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

import org.hibernate.annotations.OptimisticLockType;

/**
 * @author xialong<longxia1987@hotmail.com>
 *
 */
@Entity
@Table(name="t_user")
@org.hibernate.annotations.Entity(optimisticLock = OptimisticLockType.VERSION)
public class User extends BaseModel {
	
	private static final long serialVersionUID = 2358420388745275538L;
	
	private Integer id;
	private String userName;
	private String password;
	private Date version;
	
	@Id
	@Column(name="id")
	@GeneratedValue(strategy=GenerationType.AUTO)
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	
	@Column(name="user_name",length=50)
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	@Column(name="password",length=50)
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
	@Version
	@Column(name="version")
	public Date getVersion() {
		return version;
	}
	public void setVersion(Date version) {
		this.version = version;
	}
}

使用：

/**
 * 
 */
package com.longxia.springmvc.dao.userdao;

import java.util.List;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;

import com.longxia.springmvc.dao.HibernateBaseDao;
import com.longxia.springmvc.model.User;

/**
 * @author xialong
 *
 */
@Component
public class UserDaoImpl extends HibernateBaseDao<User> implements IUserDao {
	@Resource
	private SessionFactory springmvcSessionFactory;
	@PostConstruct
	public void initSessionFactory() {
		super.setSessionFactory(springmvcSessionFactory);
	}
	/* (non-Javadoc)
	 * @see com.longxia.springmvc.dao.userdao.IUserDao#findAllUsers()
	 */
	@Override
	public List<User> findAllUsers() {
		String hql = "from User";
		return this.getHibernateTemplate().find(hql);
	}
	
}
