结构：

 

Spring和Hibernate整合借助于HibernateTemplate

 

applicationContext.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:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"

    <bean name="c" class="com.lc.pojo.Category">
        <property name="name" value="yyy" />
    </bean>
    
    <bean name="dao" class="com.lc.dao.CategoryDAO">
        <property name="sessionFactory" ref="sf" />
    </bean>

    <bean name="sf"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="ds" />
        <property name="mappingResources">
            <list>
                <value>com/lc/pojo/Category.hbm.xml</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <value>
                hibernate.dialect=org.hibernate.dialect.mysqlDialect
                hibernate.show_sql=true
                hbm2ddl.auto=update
               </value>
        </property>
    </bean>    
        
<!--    数据源-->
    <bean name="ds"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/test?characterEncoding=GBK" />
        <property name="username" value="root" />
        <property name="password" value="123456" />
    </bean>    
 
</beans>

测试：

ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
        CategoryDAO bean =(CategoryDAO) context.getBean("dao");

        DetachedCriteria criteria = DetachedCriteria.forClass(Category.class);

//        List<Category> list = bean.findByCriteria(criteria, 0, 5); //分页--取0-5个返回
//        System.out.println(list);

 

 Category.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.lc.pojo">

    <class name="Category" table="category_">
        <id name="id" column="id">
            <generator class="native">
            </generator>
        </id>
        <property name="name" />
    </class>

</hibernate-mapping>
