Spring基于注解的配置

    <context:component-scan base-package="com.txazo" />

Spring自动扫描组件，配置了它，就无需配置<context:annotation-config />。

<context:component-scan base-package="com.txazo"><context:include-filter type="regex"expression=".dao.impl.*" /><context:include-filter type="regex"expression=".service.impl.*" /><context:include-filter type="regex"expression=".action.*" /></context:component-scan>

<context:annotation-config />

向Spring容器注册AutowiredAnnotationBeanPostProcessor、CommonAnnotationBeanPostProcessor、PersistenceAnnotationBeanPostProcessor 、RequiredAnnotationBeanPostProcessor这4个BeanPostProcessor，然后Spring就可以识别相应的注解。

<aop:aspectj-autoproxy />

AOP切面配置，Spring自动为配置@aspectJ切面的bean创建代理。

<bean               />

Spring对任何带有@Repository注解的对象自动激活其数据访问异常转换。

<tx:annotation-driven transaction-manager="transactionManager" />

Spring的事务管理器，可以使用@Transactional注解配置声明式事务。
Spring结合Hibernate基于注解的配置如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:p="http://www.springframework.org/schema/p"         xmlns:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="            http://www.springframework.org/schema/beans            http://www.springframework.org/schema/beans/spring-beans.xsd            http://www.springframework.org/schema/aop            http://www.springframework.org/schema/aop/spring-aop.xsd            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"><!-- Spring Component Scan --><context:component-scan base-package="com.txazo" /><!-- Spring AOP Aspectj Autoproxy --><aop:aspectj-autoproxy /><!-- Spring DataAccessException Annotated With @Repository --><bean        /><!-- SessionFactory --><bean id="sessionFactory"        /><!-- HibernateTemplate --><bean id="hibernateTemplate"            /><!-- TransactionManager --><bean id="transactionManager"    /><!-- Declarative Transaction Management --><tx:annotation-driven transaction-manager="transactionManager" /></beans>
