1.名称匹配方法切入点顾问

接口：ISomeService

public interface ISomeService {
    public void doSome();

    public void doSecont();
    
}

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！");
    }

    public void doSecont() {
        System.out.println("=================Secont================");

    }
    
}

单测

//1.前置通知 名称匹配方法切入点顾问
    @Test
    public void test01(){
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext05_aop05_Advice.xml");
        ISomeService service = (ISomeService) ctx.getBean("proxyService");
        service.doSome();
        service.doSecont();
    }

2.正则表达式 匹配方法切入点顾问

接口：ISomeService

public interface ISomeService {
    public void doSome();

    public void doSecont();
}

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！");
    }

    public void doSecont() {
        System.out.println("++===================Secont====================++");

    }


}
