本文介绍了一个使用AOP（面向切面编程）在Java应用中记录日志和构建订单的过程。通过@Async和@AfterReturning注解，实现了对RechargeService.buildOrder方法的异步日志记录及结果处理。详细展示了如何从方法返回结果中提取关键参数，并调用coreWebOrderApi.buildOrder方法完成订单构建。

        log.info("*****************************************");
        log.info("*****************************************");
        //保存所有请求参数，用于输出到日志中
//        Map allParams = new HashMap();
        /*Object[] paramValues = joinPoint.getArgs();
        String[] paramNames = ((CodeSignature) joinPoint.getSignature()).getParameterNames();
        for(int i=0;i<paramNames.length;i++){
            if (paramValues[i] instanceof Map<?, ?>) {
                //提取方法中的MAP参数，用于记录进日志中
                @SuppressWarnings("unchecked")
