spring_hibernate_Template4

一。测试

public class UserServiceTest {
	public static void main(String[] args) {
		ApplicationContext ac =  new ClassPathXmlApplicationContext("applicationContext.xml");
		UserService service = (UserService)ac.getBean("userService");
		User u = new User();
		u.setName("haha success!!");
		service.add(u);
	}
}

二。service服务层

@Component
public class UserService {
	
	private UserDAO userDAO;
	private LogDAO logDAO;
	
	//@Transactional
	public void add(User u){
		this.userDAO.save(u);
		Log log = new Log();
		log.setMessage("a object saved!");
		this.logDAO.save(log);
	}

	@Resource(name="userDAOImpl")
	public void setUserDAO(UserDAO userDAO) {
		this.userDAO = userDAO;
	}
	@Resource(name="logDAOImpl")
	public void setLogDAO(LogDAO logDAO) {
		this.logDAO = logDAO;
	}
	
	public UserDAO getUserDAO() {
		return userDAO;
	}
	public LogDAO getLogDAO() {
		return logDAO;
	}
}

三。dao接口

public interface LogDAO {
	public void save(Log log);
}


public interface UserDAO {
	public void save(User u);
}

四。dao实现

//直接将hibernateTemplate组件，通过@Resource注入
@Component
public class LogDAOImpl implements LogDAO{
	
	private HibernateTemplate hibernateTemplate;
	
	public void save(Log log){
		hibernateTemplate.save(log);
	}

	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}
	@Resource(name="hibernateTemplate")
	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}
}


//调用继承父类获得Template，可以继承以下三种父类Template
@Component
public class UserDAOImpl extends SuperDAO2 implements UserDAO{
	public void save(User u) {
		this.getHibernateTemplate().save(u);
	}
}

五。三种父类

@Component
public class SuperDAO {
	private HibernateTemplate hibernateTemplate;

	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}
	
	@Resource
	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}

}
//直接将hibernateTemplate组件，通过@Resource注入父类，不继承何类

@Component
public class SuperDAO2 extends HibernateDaoSupport{
	
	@Resource
	public void setSuperHibernateTemplate(HibernateTemplate hibernateTemplate) {
		super.setHibernateTemplate(hibernateTemplate);
	}
}
//直接将hibernateTemplate组件，设置成HibernateDaoSupport的hibernateTemplate属性

@Component
public class SuperDAO3 extends HibernateDaoSupport{
	
	@Resource
	public void setSuperSessionFactory(SessionFactory sessionFactory){
		super.setSessionFactory(sessionFactory);
	}

}
//直接将sessionFactory，设置成HibernateDaoSupport的sessionFactory属性

六。spring的application.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- 配置自动装配 AutowiredAnnotationBeanPostProcessor等接口，实现所有注入等功能 -->
	<context:annotation-config/>
	<!-- 配置扫描包路径，将包下所有组件实例化 -->
	<context:component-scan base-package="com.job"/>
	
	<!-- 在spring容器中，创建数据库连接Bean -->
    <bean id="DataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

        <property name="username" value="root"/>
        <property name="password" value="admin"/>
    </bean>
    
	<!-- 创建hibernate的sessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    	<!-- 将spring容器中存在的数据库连接Bean，配置到sessionFactory中 -->
        <property name="dataSource" ref="DataSource"/>
        
        <!-- 配置hibernate映射实体对象到表的文件（一） -->
         <property name="packagesToScan">
            <list>
                <value>com.job.model</value>
            </list>
        </property>
  
        <!-- 配置hibernate属性，方言，显示sql，是否创建数据表 -->
        <property name="hibernateProperties">
        	<props>
        		<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
        		<prop key="hibernate.show_sql">true</prop>
        		<prop key="hibernate.hbm2ddl.auto">update</prop>
        	</props>
        </property>
    </bean>
    
    <!-- 注入sessionFactory,获得spring的HibernateTemplate -->
    <!--设置成HibernateDaoSupport的sessionFactory属性不需要HibernateTemplate -->
    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate">
    	 <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
   
</beans>

七。实体类

@Entity 
@Table(name="log")
public class Log {
	private int id;
	private String message;
	

	public String getMessage() {
		return message;
	}

	public void setMessage(String message) {
		this.message = message;
	}
	@Id
	@GeneratedValue
	public int getId() {
		return id;
	}

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

@Entity 
@Table(name="Users")
public class User {
	private int id;
	private String name;
	
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	@Id
	@GeneratedValue
	@Column(name="USER_ID")
	public int getId() {
		return id;
	}

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