如下，这是源码
接口
package test.spring.aop.bean;
public interface Eatable {
public void eat();
}
实现类
package test.spring.aop.bean;
public class EatLunch implements Eatable {
public void eat() {
System.out.println("吃午饭...");
}
}
通知
package test.spring.aop.bean;
import java.lang.reflect.Method;
import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;
public class EatHelper implements MethodBeforeAdvice,AfterReturningAdvice{
public void afterReturning(Object arg0, Method arg1, Object[] arg2,
Object arg3) throws Throwable {
System.out.println("吃完饭去刷牙了。。");
}
public void before(Method arg0, Object[] arg1, Object arg2)
throws Throwable {
System.out.println("要吃饭了，去洗手了。。");
}
}

junit测试类
package test;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import test.spring.aop.bean.Eatable;
public class Test_SpringAop2 {
@Test
public void test1(){
ApplicationContext appCtx = new ClassPathXmlApplicationContext("app3.xml");
Eatable eatable = (Eatable)appCtx.getBean("eatLunch");
eatable.eat();
}
}
运行之后junit报错，如下：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eatLunch' defined in class path resource [app3.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eatHelperAdvisor' defined in class path resource [app3.xml]: Cannot resolve reference to bean '.*eat' while setting bean property 'pattern'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named '.*eat' is defined
采用手动代理配置可以得到正确结果，如下：
