# springboot 上传文件记录日志是报错It is illegal to call this method if the current request is not in asynchronous mode (i.e. isAsyncStarted() returns false) #

原因，因为Object\[\] args = joinPoint.getArgs();会得到多余的ServletRequest，MultipartFile等，而这些入参并不能进行序列化。这里我们将args进行处理：

// 请求的参数
    		Object[] args = joinPoint.getArgs();
    		// 将参数所在的数组转换成json
    		Object[] arguments = new Object[args.length];
    		for (int i = 0; i < args.length; i++) {
    			if (args[i] instanceof ServletRequest || args[i] instanceof ServletResponse
    					|| args[i] instanceof MultipartFile) {
    				/* ServletRequest不能序列化，从入参里排除，否则报异常：java.lang.IllegalStateException: It is
    				illegal to call this method if the current request is not in asynchronous
    				mode (i.e. isAsyncStarted() returns false)
    				ServletResponse不能序列化 从入参里排除，否则报异常：java.lang.IllegalStateException:
    				getOutputStream() has already been called for this response*/
    				continue;
    			}
    			arguments[i] = args[i];
    		}
    		String paramter = "";
    		if (arguments != null) {
    			try {
    				paramter = JSONArray.fromObject(arguments).toString();
    			} catch (Exception e) {
    				paramter = arguments.toString();
    			}
    		}

将不能进行序列化的入参过滤掉，只要留下我们需要记录的入参参数记录到日志中即可。
