springBoot AOP测试

声明：代码是JavaEE开发的颠覆者 Spring Boot实战代码中的，我只是拿去学习。
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Action {
    String name();
}




@Configuration
@ComponentScan("com.wisely.highlight_spring4.ch1.aop")
@EnableAspectJAutoProxy //1 开启对AOP的支持
public class AopConfig {

}



@Service
public class DemoAnnotationService {
	@Action(name="注解式拦截的add操作")
    public void add(){} 
   
}



@Service
public class DemoMethodService {
	public void add(){}
}




@Aspect //1 声明切面
@Component //2
public class LogAspect {
	
	@Pointcut("@annotation(com.wisely.highlight_spring4.ch1.aop.Action)") //3
	public void annotationPointCut(){};
	
	  @After("annotationPointCut()") //4
	    public void after(JoinPoint joinPoint) {
	        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
	        Method method = signature.getMethod();
	        Action action = method.getAnnotation(Action.class); 
	        System.out.println("注解式拦截 " + action.name()); //5
	    }
	  
	   @Before("execution(* com.wisely.highlight_spring4.ch1.aop.DemoMethodService.*(..))") //6
	    public void before(JoinPoint joinPoint){
	        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
	        Method method = signature.getMethod();
	        System.out.println("方法规则式拦截,"+method.getName());

	    }
}



public class Main {
	public static void main(String[] args) {
		 AnnotationConfigApplicationContext context =
	                new AnnotationConfigApplicationContext(AopConfig.class); //1
		 
		 DemoAnnotationService demoAnnotationService = context.getBean(DemoAnnotationService.class);
		 
		 DemoMethodService demoMethodService = context.getBean(DemoMethodService.class);
		 
		 demoAnnotationService.add();
		 
		 demoMethodService.add();
		 
		 context.close();
	}
}
