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();    }
