修改類:
/spring+hibernate_hibernateDaoSupport/src/com/b510/service/impl/PersonServiceBean.java
 1 package com.b510.service.impl;
 2
 3 import java.util.List;
 4
 5 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
 6 import org.springframework.transaction.annotation.Propagation;
 7 import org.springframework.transaction.annotation.Transactional;
 8
 9 import com.b510.domain.Person;
10 import com.b510.service.PersonService;

12 /**

18 public class PersonServiceBean extends HibernateDaoSupport implements
19         PersonService {
20
21     @Override
22     public void delete(Integer id) {
23         getHibernateTemplate().delete(getPerson(id));
24     }
25
26     // 在查詢的時候,不需要開啟事務,並且指定為隻讀,這樣可以提高查詢效率
27     @Override
28     @Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true)
29     public Person getPerson(Integer id) {
30         return (Person) getHibernateTemplate().get(Person.class, id);
31     }
32
33     // 在查詢的時候,不需要開啟事務,並且指定為隻讀,這樣可以提高查詢效率
34     @Override
35     @Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true)
36     @SuppressWarnings("unchecked")
37     public List<Person> getPerson() {
38         return getHibernateTemplate().find("from Person");
39     }
40
41     @Override
42     public void save(Person person) {
43         getHibernateTemplate().save(person);
44     }
45
46     @Override
47     public void update(Person person) {
48         getHibernateTemplate().update(person);
49     }
50 }

/spring+hibernate_hibernateDaoSupport/src/bean.xml
修改為這樣:
1     <bean id="personService" class="com.b510.service.impl.PersonServiceBean">
2         <property name="sessionFactory" ref="sessionFactory"></property>
3     </bean>

HibernateDaoSupport提供瞭如下方法:
public final HibernateTemplate getHibernate();
public final void setSessionFactory(SessionFactory sessionFactory)
運行效果:
 1 log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
 2 log4j:WARN Please initialize the log4j system properly.
 3 Hibernate:
 4     select
 5         max(id)
 6     from
 7         person
 8 Hibernate:
 9     insert
10     into
11         spring.person
12         (name, age, sex, id)
13     values
14         (?, ?, ?, ?)
15 Hibernate:
16     select
17         person0_.id as id0_0_,
18         person0_.name as name0_0_,
19         person0_.age as age0_0_,
20         person0_.sex as sex0_0_
21     from
22         spring.person person0_
23     where
24         person0_.id=?
25 Hibernate:
26     update
27         spring.person
28     set
29         name=?,
30         age=?,
31         sex=?
32     where
33         id=?
34 Hibernate:
35     select
36         person0_.id as id0_0_,
37         person0_.name as name0_0_,
38         person0_.age as age0_0_,
39         person0_.sex as sex0_0_
40     from
41         spring.person person0_
42     where
43         person0_.id=?
44 Hibernate:
45     select
46         person0_.id as id0_,
47         person0_.name as name0_,
48         person0_.age as age0_,
49         person0_.sex as sex0_
50     from
51         spring.person person0_

66         person0_.name as name0_0_,
67         person0_.age as age0_0_,
68         person0_.sex as sex0_0_
69     from

結果是一樣一樣的哦。
