spring+hibernate--HibernateTemplate的使用

Spring对hibernate的使用做了些封装，之前hibernate是用

Session session=sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();

现在使用HibernateTemplate来管理持久化 ，把sessionFactory封装进了HibernateTemplate

下面是一个例子：

引入一下包：

spring核心配置文件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:context="http://www.springframework.org/schema/context"
      xmlns:aop="http://www.springframework.org/schema/aop"
      xsi:schemaLocation="

           http://www.springframework.org/schema/aop 
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
           
 <bean id="DataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/test"/>
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>
      
  </bean>
  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="DataSource"/>
    <property name="mappingResources">
      <list>
        <value>vo/Tbuser.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="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
       <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>
 <bean id="userDao" class="dao.UserDAO">
   <property name="hibernateTemplate" ref="hibernateTemplate"></property>
 </bean>
</beans>

相关java类：

package dao;

import org.hibernate.Hibernate;
import org.springframework.orm.hibernate3.HibernateTemplate;
import vo.Tbuser;
public class UserDAO {
private HibernateTemplate hibernateTemplate;


public void create(Tbuser user){
hibernateTemplate.save(user);
}


public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}


public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}

}

package vo;
public class Tbuser implements java.io.Serializable {
private Integer id;
private String username;
private Integer age;
private String address;

public Tbuser() {
}

public Tbuser(String username, Integer age, String address) {
this.username = username;
this.age = age;
this.address = address;
}

public Integer getId() {
return this.id;
}

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

public String getUsername() {
return this.username;
}

public void setUsername(String username) {
this.username = username;
}

public Integer getAge() {
return this.age;
}

public void setAge(Integer age) {
this.age = age;
}

public String getAddress() {
return this.address;
}

public void setAddress(String address) {
this.address = address;
}

}

hibernate映射文件：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- 
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
    <class name="vo.Tbuser" table="tbuser" catalog="test">
        <id name="id" type="java.lang.Integer">
            <column name="id" />
            <generator class="identity" />
        </id>
        <property name="username" type="java.lang.String">
            <column name="username" length="20" />
        </property>
        <property name="age" type="java.lang.Integer">
            <column name="age" />
        </property>
        <property name="address" type="java.lang.String">
            <column name="address" length="20" />
        </property>
    </class>
</hibernate-mapping>

测试类：

package test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import vo.Tbuser;
import dao.UserDAO;

public class Test {

@org.junit.Test
   public void testcreate(){
ApplicationContext cfg= new ClassPathXmlApplicationContext("beans.xml");
UserDAO dao=(UserDAO)cfg.getBean("userDao");
Tbuser user=new Tbuser();
user.setUsername("晟碟");
user.setAge(4);
user.setAddress("月球");
dao.create(user);
   }
}
