MethodInterceptor  --> org.springframework.aop.support.RegexpMethodPointcutAdvisor
ThrowsAdvice --> org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator

接口:

package com.app.aop;

public interface IBizProcessImpl {
	void doOneThing();
    void doAnotherThing();
}

实现类:

package com.app.aop;


public class BizProcessImpl implements IBizProcessImpl {

	public void doOneThing() {
		System.out.println("doOneThing-->");

	}

	public void doAnotherThing() {
		System.out.println("doAnotherThing-->");
		int i =1/0;//模拟出现异常
		//throw new RuntimeException("Boom");

	}

}

ThrowsAdvice类

package com.app.aop;

import java.lang.reflect.Method;

import org.springframework.aop.ThrowsAdvice;

public class MyThrowsAdvice implements ThrowsAdvice {
	public void afterThrowing(Method method, Object[] args, Object target, Exception ex){
		System.out.println("-----------------afterThrowing message start-----------------");
		System.out.println("Method Name="+method.getName());
		for(int i=0; i<args.length; i++){
			System.out.println(args[i]);
		}
		System.out.println("Target Class Name="+target.getClass().getName());
		System.out.println("Exception Class Name="+ex.getClass().getName());
		System.out.println("Exception Message="+ex.getMessage());
		System.out.println("-----------------afterThrowing message end-----------------");
	}
	public void afterThrowing(Exception ex){
		System.out.println("-----------------afterThrowing message start-----------------");
		System.out.println("Exception Class Name="+ex.getClass().getName());
		System.out.println("Exception Message="+ex.getMessage());
		System.out.println("-----------------afterThrowing message end-----------------");
	}
}

applicationContext.xml配置:
配置A:

	<bean id="bizOneTarget" class="com.app.aop.BizProcessImpl"></bean>
	<bean id="throwsAdvice" class="com.app.aop.MyThrowsAdvice"></bean>
	<bean id="bizOne" class="org.springframework.aop.framework.ProxyFactoryBean">
		<property name="proxyInterfaces">
			<value>com.app.aop.IBizProcessImpl</value>
		</property>
		<property name="target">
			<ref bean="bizOneTarget" />
		</property>
		<property name="interceptorNames">
			<list>
				<value>throwsAdvice</value>
			</list>
		</property>
	</bean>

Java测试类:

public static void main(String[] args) {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
		IBizProcessImpl t = ctx.getBean("bizOne",IBizProcessImpl.class);
		//IBizProcessImpl t = ctx.getBean("bizOneTarget",IBizProcessImpl.class);
		try {
			t.doAnotherThing();
		} catch (Exception e) {
			// TODO: handle exception
		}
		
	}

配置B:

<bean id="bizOneTarget" class="com.app.aop.BizProcessImpl"></bean>
	<bean id="throwsAdvice" class="com.app.aop.MyThrowsAdvice"></bean>
	<bean id="beanNameAutoProxyCreator"
	class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
	<property name="beanNames">
		<list>
			<value>*bizOneTarget</value>//可以用通配符
		</list>
	</property>
	<property name="interceptorNames">
		<value>throwsAdvice</value>
	</property>

Java测试类:

public static void main(String[] args) {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
		//IBizProcessImpl t = ctx.getBean("bizOne",IBizProcessImpl.class);
		IBizProcessImpl t = ctx.getBean("bizOneTarget",IBizProcessImpl.class);
		try {
			t.doAnotherThing();
		} catch (Exception e) {
			// TODO: handle exception
		}
		
	}
