AOP拦截日志类，抛异常：java.lang.IllegalStateException: It is illegal to call this method if the current request is not in asynchronous mode

AOP的日志拦截类中，抛出异常：

java.lang.IllegalStateException: It is illegal to call this method if the current request is not in asynchronous mode

主要原因：对方法的参数使用JSON.toJSONString(args[index])转换时，有异常抛出【如果参数类型是请求和响应的http，使用JSON.toJSONString()转换会抛异常】

解决方案：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
