1.定义注解

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface LogPoint {
}

2.切面实现

@Slf4j
@Aspect
@Component
@Order(20)
public class LogPointAspect {
    //this is test fork
    @Before("@annotation(com.trendsi.trace.aop.LogPoint)")
    public void before(JoinPoint joinPoint) {
        String merchantCode = UserUtils.getUserInfo().getMerchantCode();
        log.info("----------------LogPointAspect before:{}", merchantCode);
    }
    @After("@annotation(com.trendsi.trace.aop.LogPoint)")
    public void after(JoinPoint joinPoint) {
        String merchantCode = UserUtils.getUserInfo().getMerchantCode();
        log.info("---------------LogPointAspect after:{}", merchantCode);
    }
}

3.注意事项

aop加载顺序，自定义aop的顺序，要确保在框架提供的aop之后执行。即@order参数需要大于20
