spring增强

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");

    }

2.后置增强

接口：ISomeService 

public interface ISomeService {
    public void doSome();

        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");

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