spring-aop-aspectj(Schema)-case

基于Schema 配置切面:
1、切点定义的语言依然是AspectJ表达式语言
2、把不用AspectJ相关的注解定义切面,而是通过xml配置,相当于注解的xml表达的aop定义形式。

定义advice增强
public class LoginMonitorAspectj {
	public static final ThreadLocal<Long> time = new ThreadLocal<Long>();

	public void before(JoinPoint pjp) {
		time.set(System.currentTimeMillis());
		System.out.println("invoke before --------------------------------");
		System.out.println(pjp.toLongString());
		System.out.println(Arrays.toString(pjp.getArgs()));
	}
	public void afterReturning(JoinPoint pjp,User user) {
		System.out.println("invoke afterReturning ---------------------------------");
		System.out.println(user.toString());
		System.out.println("times : "+(System.currentTimeMillis() - time.get()));
	}
	public void _exception(JoinPoint pjp,Exception ex) {
		System.out.println("invoke _exception ---------------------------------");
		System.out.println("times : "+(System.currentTimeMillis() - time.get()));
	}
}



业务方法定义
@Service
public class LoginService implements ILoginService {

	public User login(String username, String password) {
		User user = new User();
		System.out.println("in login method");
		user.setPassword("123456");
		user.setUsername("admin");
		return user;
	}

	@MethodExecuteTimes
	public void regist(String username, String password, String email, int age) {
		   System.out.println(Arrays.toString(new Object[]{username,password,age}));
	}

}


配置applicationContext.xml

<context:component-scan base-package="org.job">
		<context:include-filter type="annotation"
			expression="org.springframework.stereotype.Service" />
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
	<aop:aspectj-autoproxy/> 
	
	<bean id="adviceMethods" class="org.job.user.aop.LoginMonitorAspectj"/>
	
	<aop:config>
	   <aop:aspect ref="adviceMethods">
	        <aop:before pointcut="execution(* login(..))" method="before"/>
	        <aop:after-returning pointcut="execution(* login(..))" method="afterReturning" returning="user"/>
	        <aop:after-throwing pointcut="execution(* login(..))" method="_exception" throwing="ex"/>
	   </aop:aspect>
	</aop:config>
</beans>
