spring aop的annotation配置

首先在applicationContext.xml启动@AspectJ的支持，即添加：

<aop:aspectj-autoproxy/>

然后Advice所使用的Bean需要在配置文件定义，添加后如下：

<?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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
    http://www.springframework.org/schema/aop

    <bean
        id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName">
            <value>org.apache.derby.jdbc.EmbeddedDriver</value>
        </property>
        <property name="url">
            <value>jdbc:derby:f:/zwh/mydb2</value>
        </property>
        <property name="username">
            <value>root</value>
        </property>
        <property name="password">
            <value>root</value>
        </property>
    </bean>
    <bean
        id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource"/>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect"> org.hibernate.dialect.DerbyDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>
        <property name="annotatedClasses">
            <list>
                <value>zwh.ssh.maven.po.User</value>
            </list>
        </property>
    </bean>
    <context:component-scan base-package="zwh.ssh.maven"></context:component-scan>
    <bean class="zwh.ssh.maven.aop.ServiceAdvice"></bean>
    <aop:aspectj-autoproxy/>
</beans>

ServiceAdvice.java内容如下：

@Aspect
public class ServiceAdvice {
	static Logger log = Logger.getLogger(ServiceAdvice.class);
	
	@Before("execution(* zwh.ssh.maven.service.impl.*.*(..))")
	public void before(JoinPoint jp) {
		log.info("before:" + "在方法" + jp.getSignature().getName()
				+ "之前执行");
		log.info("before:" + "方法的参数" + Arrays.toString(jp.getArgs()));
		log.info("before:" + "方法的目标对象" + jp.getTarget());
	}

	@AfterReturning(returning="rvt",
			pointcut="execution(* zwh.ssh.maven.service.impl.*.*(..))")
	public void afterReturning(JoinPoint jp, Object rvt) {
		log.info("afterReturning:" + jp.getSignature().getName() + "方法返回"
				+ rvt);
	}
	
	@AfterThrowing(throwing="ex",
			pointcut="execution(* zwh.ssh.maven.service.impl.*.*(..))")
	public void afterThrowing(JoinPoint jp, Throwable ex) {
		log.info("afterThrowing:" + jp.getSignature().getName()
				+ "抛出异常" + ex);
	}
	
	@After("execution(* zwh.ssh.maven.service.impl.*.*(..))")
	public void after() {
		log.info("after:" + "在方法之后执行");
	}

	@Around("execution(* zwh.ssh.maven.service.impl.*.*(..))")
	public Object around(ProceedingJoinPoint pjp) throws Throwable {
		log.info("around:" + "在方法" + pjp.getSignature().getName()
				+ "之前执行");
		Object[] args = pjp.getArgs();
		log.info("around:" + "方法的参数" + Arrays.toString(args));
		Object rvt = pjp.proceed(args);
		log.info("around:" + "方法" + pjp.getSignature().getName()
				+ "的返回值" + rvt);
		return rvt;
	}
}
