1.前置增强

接口：ISomeService

public interface ISomeService {    public void doSome();}

类

public class MyBeforeAdvise implements MethodBeforeAdvice {    public void before(Method method, Object[] objects, Object o) throws Throwable {        System.out.println("==========log==========");    }}

public class SomeService implements ISomeService{    //核心业务    public void doSome() {        System.out.println("拜托别让他一番努力换来是奢求！");    }    }

配置文件

单测

//前置增强    @Test    public void test05(){        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext01_aop01.xml");        SomeService service = (SomeService) ctx.getBean("proxyService");        service.doSome();    }

2.后置增强

接口：ISomeService

public interface ISomeService {    public void doSome();}

类

public class MyAfterReturningAdvice implements AfterReturningAdvice {    public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {        System.out.println("==========after==========");    }}

public class SomeService implements ISomeService {    //核心业务    public void doSome() {        System.out.println("拜托别让他一番努力换来是奢求！");    }}

配置文件

单测

//后置增强    @Test    public void test06(){        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext02_aop02.xml");        ISomeService service = (ISomeService) ctx.getBean("proxyService");        service.doSome();    }

3.环绕增强

接口：ISomeService

public interface ISomeService {    public void doSome();}

类

public class MyMethodInterceptor implements MethodInterceptor {    public Object invoke(MethodInvocation methodInvocation) throws Throwable {        System.out.println("before");        methodInvocation.proceed();        System.out.println("after");        return null;    }}
