切面打印日志时,参数序列化异常
异常信息:java.lang.IllegalStateException: It is illegal to call this method if the current request is not in asynchronous mode (i.e. isAsyncStarted() returns false)
原因
joinPoint.getArgs()返回的数组中携带有Request或者Response对象,导致序列化异常。
解决方案:去除Request或者Response对象
// JSONArray json=JSONArray.fromObject(joinPoint.getArgs()); Object[] args = joinPoint.getArgs(); Stream<?> stream = ArrayUtils.isEmpty(args) ? Stream.empty() : Arrays.stream(args); List<Object> logArgs = stream .filter(arg -> (!(arg instanceof HttpServletRequest) && !(arg instanceof HttpServletResponse))) .collect(Collectors.toList()); //过滤后序列化无异常 JSONArray json=JSONArray.fromObject(logArgs);
