基于注解的AOP日志切面控制SpringAOP

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());
    }


}
