Spring2.5注解式的配置

最近通过找资料研究了一下Spring2.5 AOP注解式事务的配置.发现确实比以前写XML简单的多.

ApplicationContext_common.xml的代码如下

<?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"  
 xsi:schemaLocation="   
   http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd   
   http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd   
   http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">   
  
 <!-- 配置一下SessionFactory -->   
 <bean id="sessionFactory"  
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">   
  <property name="configLocations">   
   <value>classpath:hibernate.cfg.xml</value>   
  </property>   
 </bean>   
  
 <!-- 配置一下事务管理器 -->   
 <bean id="transactionManager"  
  class="org.springframework.orm.hibernate3.HibernateTransactionManager">   
  <property name="sessionFactory" ref="sessionFactory"/>   
 </bean>   
    
 <!-- 配置一下事务的传播特性 -->   
 <tx:advice id="txadvice" transaction-manager="transactionManager">   
  <tx:attributes>   
   <tx:method name="insert*" propagation="REQUIRED"/>   
   <tx:method name="update*" propagation="REQUIRED"/>   
   <tx:method name="delete*" propagation="REQUIRED"/>   
   <tx:method name="*" read-only="true"/>   
   <tx:method name="*" rollback-for="Exception"/>   
  </tx:attributes>   
 </tx:advice>   
    
 <!-- 配置哪些方法参与事务 -->   
 <aop:config>   
  <aop:pointcut expression="execution(* com.wang.sprhiber.service.*.*(..))" id="allmethod"/>   
  <aop:advisor advice-ref="txadvice" pointcut-ref="allmethod"/>   
 </aop:config>   
</beans>  

这个是配置的核心.

注入的核心XML代码如下:

<?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"  
 xmlns:context="http://www.springframework.org/schema/context"  
 xsi:schemaLocation="   
   http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd   
   http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd   
   http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd   
 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd    
 ">  
    
 <context:component-scan base-package="com.wang.sprhiber"/>  
    
 <bean id="memberDAO" class="com.wang.sprhiber.dao.implay.MemberDAOImplay">  
  <property name="sessionFactory" ref="sessionFactory"/>  
 </bean>  
</beans>  

Service采用注解来注入.

package com.wang.sprhiber.service.implay;   
  
import javax.annotation.Resource;   
  
import org.springframework.stereotype.Component;   
  
import com.wang.sprhiber.dao.ImemberDAO;   
import com.wang.sprhiber.pojo.Member;   
import com.wang.sprhiber.service.IMemberService;   
  
@Component("memberServiceProxy")   
public class MemberServiceImplay implements IMemberService   
{   
 @Resource(name = "memberDAO")   
 private ImemberDAO memberDAO;   
  
 public int insertOneMemService(Member member)   
 {   
  return this.memberDAO.insertOneMemDAO(member);   
 }   
  
}  

DAO层由于SessionFactory没有办法注入,只能写在XML文件里面了

用这种注入的方式,可以省去在XML文件里面写多个需要代码的Service.这种方式可以通过简单的正则表达式来配置整个包下面的所有类.
