spring学习----aop配置demo

注意

aop:aspect   切面类是普通类即可
aop:advisor  切面类必须实现  advice接口   如：MethodBeforeAdvice    AfterReturningAdvice等

定义通知（实现Advice）

public class MyAfterAdvice implements AfterReturningAdvice {
@Override
public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
System.out.println("=========我是afterReturn通知方法=============");
}
}

public class MyBeforeAdvice implements MethodBeforeAdvice{
@Override
public void before(Method method, Object[] objects, Object o) throws Throwable {
System.out.println("=========我是前置通知方法=============");
}
}

普通通知（不实现Advice）

public class MyNoAdvice {
public void before() throws Throwable {
System.out.println("=============我的普通的before前置方法====================");
}

public void after() throws Throwable {
System.out.println("=============我的普通的After后置方法====================");
}
}

业务类

public interface IBussinessService {
void bussiness();

void sayHello();
}

public class BussinessServiceImpl implements IBussinessService{
@Override
public void bussiness() {
System.out.println("=========我是业务方法==========");
}

@Override
public void sayHello() {
System.out.println("=========我是say Hello==========");
}
}

测试类

@Test
public void test1(){
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:beans.xml");
IBussinessService bussinessService =  applicationContext.getBean("bussinessService",IBussinessService.class);
bussinessService.bussiness();
}
