Spring_6_使用注解的方式实现AOP

public interface PersonService {
public void save(String naem);
public void update(String name,Integer id);
public String getPersonName(Integer id);
}

@Service
// 使用自动扫描的方式自动装配
public class PersonServiceBean implements PersonService {

@Override
public void update(String name, Integer id) {
System.out.println("调用update（）方法");
}

@Override
public String getPersonName(Integer id) {
System.out.println("调用getPersonName()方法");
return "xoxo";
}
}

/**
* 切面
*/

@Aspect
//标志为切面
@Component
// 使用自动扫描的方式自动装配

// springDaoBean.PersonServiceBean为要拦截的类，
// .*(..)表示拦截类中的所有方法
@Pointcut("execution(* springDaoBean.PersonServiceBean.*(..))")

}

// 前置通知的设定及参数的设置和获取
@Before("anyMethod() && args(name)")

}

}

// 例外置通知的设定及参数的设置和获取

// 环绕通知的设定
