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.
