  • spring开发_Spring+Hibernate_HibernateDaoSupport

    原有项目:

    http://www.cnblogs.com/hongten/archive/2012/03/15/java_spring_hibernate_hibernateTemplate.html

    修改类:

    /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;
    11
    12 /**
    13 * 使用注解方式进行事务管理
    14 *
    15 * @author Hongten
    16 *
    17 */
    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 // 在查询的时候,不需要开启事务,并且指定为只读,这样可以提高查询效率
    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 // 在查询的时候,不需要开启事务,并且指定为只读,这样可以提高查询效率
    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

    修改为这样:

    1     <bean id="personService" class="com.b510.service.impl.PersonServiceBean">
    2 <property name="sessionFactory" ref="sessionFactory"></property>
    3 </bean>

    HibernateDaoSupport提供了如下方法:

    public final HibernateTemplate getHibernate();

    public final void setSessionFactory(SessionFactory sessionFactory)
    运行效果:

     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_

    63 Hibernate:

    65 person0_.id as id0_0_,
    66 person0_.name as name0_0_,
    67 person0_.age as age0_0_,
    68 person0_.sex as sex0_0_
    69 from
    70 spring.person person0_
    71 where
    72 person0_.id=?

    结果是一样一样的哦。
