spring3.0 MVC筆記3--從spring2.0轉向spring3.0-集成Hibernate3及聲明式事務

spring3.0 MVC筆記3

12、集成Hibernate3及聲明式事務

hibernate3提供contextual sessions，可直接在dao中使用

sessionFactory，不推薦以前的HibernateTemplate

a、聲明dataSource

 <bean id="dataSource"

class="org.logicalcobwebs.proxool.ProxoolDataSource">
     <property name="driver">
        

<value>net.sourceforge.jtds.jdbc.Driver</value>
     </property>
     <property name="driverUrl">
        

<value>jdbc:jtds:sqlserver://t18:1433;DatabaseName=tdrcc

ms;autoReconnect=true;</value>   
     </property>
     <property name="user" value="zbtbwusr" />
     <property name="password" value="aaa" />
     <property name="alias" value="tdrcpool" />
     <property name="prototypeCount" value="5" />
     <property name="maximumConnectionCount"

value="100" />
     <property name="minimumConnectionCount"

value="5" />
     <property name="simultaneousBuildThrottle"

value="50" />
  </bean>

b、聲明sessionFactory

 <bean id="sessionFactory"
  

class="org.springframework.orm.hibernate3.LocalSessionFa

ctoryBean">
  <property name="dataSource">
   <ref bean="dataSource"/>
  </property>
  <property name="configLocation">
   

<value>classpath:hibernate.cfg.xml</value>
  </property>
 </bean>

c、編寫dao

@Repository
public class UserDaoImpl implements IUserDao {
 @Autowired
 public UserDaoImpl(SessionFactory sf){
  this.sessionFactory = sf;
 }
 
 private Session getCurrentSession(){
  return sessionFactory.getCurrentSession

();
 }
 public Object addObject(Object o){
  getCurrentSession().save(o);
  return o;
 }
 public List findTopXByHQL(final String hql,

final short x)throws HibernateException,SQLException{
        Query query = getCurrentSession().createQuery

(hql);
        query.setFirstResult(0);
        query.setMaxResults(x);
        List list = query.list();
        return list;
     }
...
}

d、編寫service
@Service("helloService")
public class HelloServiceImpl implements HelloService{
 @Autowired
 public HelloServiceImpl(IUserDao dao){
  this.dao = dao;
 }
 public List<Member> listAll(){
  return dao.findListByHQL("from Member

m");
 }
...
}

e、配置事務
---
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"

http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-

3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-

context-3.0.xsd">

---
 <bean id="txManager"

class="org.springframework.orm.hibernate3.HibernateTrans

actionManager">
     <property name="sessionFactory"

ref="sessionFactory"/>
   </bean>
  <tx:advice id="txAdvice" transaction-

manager="txManager">
           <tx:attributes>
                               <tx:method name="add*"

propagation="REQUIRED" />
                               <tx:method name="delete*"

propagation="REQUIRED" />
                               <tx:method name="update*"

propagation="REQUIRED" />
                               <tx:method name="list*"

propagation="SUPPORTS" read-only="true" />
                               <tx:method name="get*"

propagation="SUPPORTS" read-only="true" />
                               <tx:method name="*" read

-only="true" />
            </tx:attributes>
 </tx:advice>
 <aop:config>
  <aop:advisor
   pointcut="execution(*

*..HelloService.*(..))"
   advice-ref="txAdvice"/>
 </aop:config>

13、spring3.0應用應包含的jar

1、基本：
org.springframework.context-3.1.2.RELEASE.jar
org.springframework.core-3.1.2.RELEASE.jar
org.springframework.expression-3.1.2.RELEASE.jar
org.springframework.asm-3.1.2.RELEASE.jar
org.springframework.beans-3.1.2.RELEASE.jar
2、依賴：
log4j-1.2.15.jar
commons-collections-3.1.jar
commons-logging-1.1.1.jar
3、spring單元測試：
org.springframework.test-3.1.2.RELEASE.jar
4、spring mvc
org.springframework.web.servlet-3.1.2.RELEASE.jar
org.springframework.web-3.1.2.RELEASE.jar
5、jstl
standard.jar
jstl.jar
6、控制器註解注入JSR-330支持，用於@Inject註解
weld-osgi-bundle.jar
7、文件處理支持FileUtils
commons-io-2.0.1.jar
8、文件上傳
commons-fileupload-1.2.2.jar
9、POJO註解驗證JSR-303支持，用於@Valid、@Size等註解的編

譯
validation-api-1.0.0.GA.jar
10、註解驗證默認實現
hibernate-validator-4.0.2.GA.jar
11、數據庫驅動及連接池
