基于注解的AOP日志切面控制SpringAOP

今天药忘吃喽~ 2022-05-14 11:58 352阅读 0赞

1.配置注解 (作用于方法上,相当于要告诉aop对哪些方法做切面植入)

import javax.jdo.annotations.Element;
    import java.lang.annotation.*;
    
    
    @Target(ElementType.METHOD)
    @Retention(RetentionPolicy.RUNTIME)
    @Documented
    public @interface AspectPointCutTag {
        String name();
    }

2.做一个aop切面(就是知道对哪些方法做植入,切面就是植入的内容或者要做的事情方法)

@Aspect
    @Component
    public class LogAspectWave {
    
        @Pointcut("@annotation(com.service.example.common.annotation.AspectPointCutTag)")
        public  void annotaionPointCut(){
            PaasLogger.info("开启切面日志记录");
        }
    
        @Before("annotaionPointCut()")
        public void bofore(JoinPoint joinPoint){
            MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
            AspectPointCutTag aspectPointCutTag  =  methodSignature.getMethod().getAnnotation(AspectPointCutTag.class);
            PaasLogger.info("前置通知:"+aspectPointCutTag.name());
        }
    
        @Before("annotaionPointCut()")
        public void after(){
    
    
        }
    }

3.给方法配置切入点

@Controller
    @EnableAspectJAutoProxy
    public class ExampleApp {
    
        @Autowired
        private ExampleService service;
    
        /**
         * 保存客户订单
         * @param req
         * @return
         */
        @PostMapping("/insert")
       @AspectPointCutTag(name="insetCustomerOrder")
        public void insert(){
            //PaasLogger.info("入参报文:"+ req.toString());
            //TODO 将改为切面日志
            service.createCustomerOrder(req.getBody());
            SaveCustomerOrderRspDTO rspDTO  = new SaveCustomerOrderRspDTO();
            //PaasLogger.info("出参报文:"+ rspDTO.toString());
        }
    
    
    }
