上一篇，已经介绍如何搭建spring mvc框架。现在融入hibernate.
spring融合hibernate，现在很多人都是不懂，然后胡乱糅合一大推包，然后项目能运行就行了，别的都不考虑。但，这对于对于每一个包的作用，知识点理解都是不方便的。所以学习，还以一步步来。下面，我来介绍如何搭建ssh框架，每个jra包作用。

需要的jar包目前就这些，其他的如果需要，自己可根据自己需要再添加。每个jar包作用，我这里都做了简要的介绍，所以不要在乱添加jar包文件了。
第二步：先创建配置文件，数据库配置文件jdbc.properties
# jdbc.X
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useOldAliasMetadataBehavior=true
jdbc.username=root
jdbc.password=root
# hibernate.X
hibernate.connection.driverClass=org.gjt.mm.mysql.Driver
hibernate.connection.url=jdbc:mysql://localhost:3306/test
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.connection.username=root
hibernate.connection.password=root
hibernate.show_sql=true
#hibernate.hbm2ddl.auto=create-drop //这里注意 如果选择create 项目启动每次会重新见表，原表数据会被删除
hibernate.hbm2ddl.auto=update
先创建hibernate实体类，可以使用逆向生成工具生成。
我这里手动创建的，只要注意相关配置参数即可
创建实体类：
package com.mx.model;
import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "user") //name对应表明
public class User {
@Id //主键
@GeneratedValue
private int id;
@Basic
@Column(name = "username")
private String username;
@Basic
@Column(name = "password")
private String password;
@Basic
@Column(name = "type")
private String type;
@Id
@Column(name = "id")
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Basic
@Column(name = "username")
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Basic
@Column(name = "password")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Basic
@Column(name = "type")
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
}
创建实体操作类：
package com.mx.dao;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import com.mx.dao.IndexDao;
import com.mx.model.User;
@Service("indexDao")
public class IndexDaoImpl implements IndexDao {
@Resource(name="sessionFactory")
private SessionFactory sessionFactory;
public List<User> getList() {
// TODO Auto-generated method stub
String hql= "from User"; //看清了，这里不是表名，而是表对应的实体类的名称
Session session=sessionFactory.getCurrentSession();
Query query=session.createQuery(hql);
return query.list();
}
}
创建操作接口
import java.util.List;
import com.mx.model.User;
public interface IndexDao {
public List<User> getList();
}
创建service层实现方法，当然，你也可以不用这样配置，我是习惯了。
package com.mx.service.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.mx.dao.IndexDao;
import com.mx.model.User;
import com.mx.service.IndexService;
@Service("indexService")
public class IndexServiceImpl implements IndexService{
@Resource
private IndexDao indexDao;
public List<User> getList(){
return indexDao.getList();
}
}
创建service接口
import java.util.List;
import org.springframework.stereotype.Service;
import com.mx.model.User;
public interface IndexService {
public List<User> getList();
}
创建controller
import java.util.List;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.mx.model.User;
import com.mx.service.IndexService;
@Controller
@RequestMapping("/index")
public class IndexController {
@Resource
private IndexService indexService;
@RequestMapping("/test")
public String index(HttpServletRequest request,HttpServletResponse response){
List<User> list=indexService.getList();
System.out.println(list);
//这里值自己处理吧，我只是打印，当然这样打印不出来list，可以用json工具自己转换，也可以在跳转后的页面用el表达式处理显示，我这里只追求流程，所以不打印数据。
request.setAttribute("user", list);
return "index1";
}
}
接着创建spring.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"

<!--引入缓存配置文件 -->
<bean id="propertiConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
<!--要是有多个配置文件，只需在这里继续添加即可 -->
</list>
</property>
</bean>
<!-- 配置自动扫描的包 -->
<mvc:annotation-driven/>
<context:annotation-config />
<context:component-scan base-package="com.mx"/>
</beans>
再创建spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
</context:component-scan>
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean

<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
接着是hibernate操作
<?xml version="1.0" encoding="UTF-8"?>

default-autowire="byName" default-lazy-init="true">
<!--配置hibernate数据源 我这里选用的是dbcp2.，其他的数据源，自己再去百度其他配置吧-->

destroy-method="close" >
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />

<!--初始化连接池 设置连接数量初始值-->

<property name="maxIdle" value="5"/>
<!--minIdle: 最小空闲连接-->
<property name="minIdle" value="3"/>
<!-- 最大链接数 -->
<property name="maxTotal" value="5"/>
</bean>
<!--hibernate session工厂-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<!--添加上面配置额数据源-->
<property name="dataSource" ref="dataSource"/>
<!--配置实体类-->
<property name="packagesToScan">

<property name="hibernateProperties">

</bean>
<!-- 配置Hibernate事务管理器 -->

<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 配置事务异常封装 -->
<bean id="persistenceExceptionTranslationPostProcessor"

<!-- 声明式容器事务管理 ,transaction-manager指定事务管理器为transactionManager -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">

<aop:config expose-proxy="true">
<!-- 只对业务逻辑层实施事务 -->
<aop:pointcut id="txPointcut" expression="execution(* com.mx.service..*.*(..))" />

</aop:config>
<aop:aspectj-autoproxy proxy-target-class="true"/>
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>
然后修改web.xml启动加载

好了。搭建完成，注解不够详细，我找时间再改，搭建有问题可以留言。
源码加数据库我放这了，自己多敲敲代码，对自己有好处。有问题欢迎交流。
