写了两天的Hibernate，到最后是数据库的链接写错了！怨呀！废话不多说，进入主题。

1. 导入jar包。用迅雷下载jar：http://dl2.cr173.com//soft3/s2sh_jar.zip

2. model类Student（在com.zjh.model下）：

package com.zjh.model;

public class Student {

	private int id;
	private String name;
	private String computerMac;
	private int num;
	private char sex;
	private int age;

	
	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public Student() {
	}

	public Student(String name, String computerMac, int num) {
		this.name = name;
		this.computerMac = computerMac;
		this.num = num;
	}
}

3. 在com.zjh.model下建立Student对应的映射文件

<?xml version="1.0" encoding="gb2312"?>
<!DOCTYPE hibernate-mapping PUBLIC
	"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
	"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="com.zjh.model.Student" table="student">
		<id name="id" column="id" type="int">
			<generator class="identity"/>
		</id>

		<property name="num" not-null="true" />
		<property name="computerMac" not-null="true" />
		<property name="name" not-null="true" />
		<property name="sex" />
		<property name="age" />

	</class>
</hibernate-mapping>

4. 在根目录下建立hibernate.cfg.xml

<!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>
		<mapping resource="com/zjh/model/student.hbm.xml"/>
	</session-factory>
</hibernate-configuration>

5. 接下来，是最重要的spring的配置文件spring.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" xmlns:ctx="http://www.springframework.org/schema/context"

		<property name="num" value="20121181" />
		<property name="name" value="zjh" />
		<property name="computerMac" value="HJ-SDF-SD-SD"/>
	</bean>

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

	</bean>

	<bean id="hibernateTemplete" class="org.springframework.orm.hibernate3.HibernateTemplate">

	</bean>

	<bean id="hibernateTransactionManager"

		<property name="transactionAttributes">

			</props>
		</property>
	</bean>
<!-- 
	<bean id="hibernateSupport" class="com.zjh.dao.HibernateSupport">
		<property name="hibernateTemplate" ref="hibernateTemplete" />
	</bean>
 -->
	<bean id="baseDao" class="com.zjh.dao.BaseDao" abstract="true"
		 >
		<property name="hibernateTemplate" ref="hibernateTemplete" />
		 </bean>

	<bean id="studentDao" class="com.zjh.dao.StudentDao" parent="baseDao">
	</bean>
</beans>

6.从上面的配置文件可以看出，还有两个自定义的类

BaseDao、StudentDao

我把它们放在model.zjh.dao下面

BaseDao

package com.zjh.dao;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public abstract class BaseDao extends HibernateDaoSupport {
	public void delete(Object object) {
		super.getHibernateTemplate().delete(object);
	}

	public void add(Object object) {
		super.getHibernateTemplate().save(object);
	}

	public void update(Object boject) {
		super.getHibernateTemplate().update(boject);
	}

	public List findByParameter(String para, String value,Object object) {
		String string = "from " + object.getClass()+" as object where " +para + "="+ value;
		return super.getHibernateTemplate().find(string);
	}
}

StudentDao

package com.zjh.dao;

import java.util.List;

import com.zjh.model.Student;

public class StudentDao extends BaseDao {
//	private Student student;
//
//	public Student getStudent() {
//		return student;
//	}
//
//	public void setStudent(Student student) {
//		this.student = student;
//	}
//	
	public void delete(Student student) {
		super.delete(student);
	}

	public void add(Student student) {
		super.add(student);
	}

	public void update(Student student) {
		super.update(student);
	}

	public List findByParameter(String para, String value,Student object) {
		String string = "from " + object.getClass()+" as object where " +para + "="+ value;
		return super.getHibernateTemplate().find(string);
	}
}

7. 好的，下面就只剩下测试了（在com.zjh.test下面建Test类）！

package com.zjh.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.zjh.dao.StudentDao;
import com.zjh.model.Student;
import com.zjh.model.SuperClass;

public class Test {
	@org.junit.Test
	public void ObjectTest() {
		SuperClass d = new SuperClass() {
		};
		Integer i = new Integer(2);
		System.out.println(i instanceof Object);
		System.out.println(d instanceof Object);
	}

	@org.junit.Test
	public void HibernateAndSpringTest() {
		ApplicationContext spring = new ClassPathXmlApplicationContext(
				"spring.xml");
		Student student = (Student) spring.getBean("student");
		StudentDao studentDao = (StudentDao) spring.getBean("studentDao");
		studentDao.add(student);
	}
	
	public static void main(String[] args) {
		ApplicationContext spring = new ClassPathXmlApplicationContext(
				"spring.xml");
		Student student = (Student) spring.getBean("student");
		StudentDao studentDao = (StudentDao) spring.getBean("studentDao");
		studentDao.add(student);
	}
}

好了，大功告成！！
