ProxyFactoryBean： spring 管理，配置interceptorNames，proxyInterfaces，target
DefaultAdvisorAutoProxyCreator：spring 自动发现PointcutAdvisor，根据PointcutAdvisor的 Pointcut 判断是否进行代理
例子：
xml 配置：
<bean id="loginServiceImpl" class="com.gym.LoginServiceImpl"/>
<bean id="ba1" class="com.gym.BeforeAdvice1"/>
<bean id="dpa1" class="org.springframework.aop.support.DefaultPointcutAdvisor">
<property name="advice" ref="ba1"/>
</bean>
<bean id="af1" class="com.gym.AfterAdvice1"/>
<bean id="dpa2" class="org.springframework.aop.support.DefaultPointcutAdvisor">
<property name="advice" ref="af1"/>
</bean>
<bean id="user" class="com.gym.User" >
<property name="username" value="xinchun.wang"/>
<property name="password" value="123456"/>
</bean>
<bean id="WelcomeAdvice" class="com.gym.WelcomeBeforeAdvice"/>
<bean id="adp3" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
<property name="pattern">
<value>com.*login</value> <!-- 业务实现方法名匹配 -->
</property>
<property name="advice">
<ref bean="WelcomeAdvice"/>
</property>
</bean>
<bean id="adp4" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
<property name="mappedNames">
<value>login</value> <!-- 业务实现方法名匹配 -->
</property>
<property name="advice">
<ref bean="WelcomeAdvice"/>
</property>
</bean>
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"/>
test：
public class LoginServiceImplTest {
public static void main(String[] args) {
ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext(
"classpath:spring/applicationContext.xml");
LoginService userService = applicationContext.getBean("loginServiceImpl",LoginService.class);
User user = new User();
user.setUsername("xinchun.wang");
user.setPassword("123456");
userService.login(user);
System.out.println(userService.getClass());
