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
完整代码:
/** * 从切点中解析出该切点对应的方法 * @param point point * @throws ClassNotFoundException * @throws IOException * @author 洪墨水 */ private void getRequestParams(ProceedingJoinPoint point, RecordMessage recordMessage) throws ClassNotFoundException, IOException { /* 类名 */ String targetObject = point.getTarget().getClass().getName(); /* 方法名 */ String methodName = point.getSignature().getName(); recordMessage.setTargetObject(targetObject); recordMessage.setMethod(methodName); Object[] args = point.getArgs(); Class<?> targetClass = Class.forName(targetObject); Method[] methods = targetClass.getMethods(); StringBuilder requestBuilder = new StringBuilder(0); /** * 遍历方法 获取能与方法名相同且请求参数个数也相同的方法 */ for (Method method : methods) { if (!method.getName().equals(methodName)) { continue; } Class<?>[] classes = method.getParameterTypes(); if (classes.length != args.length) { continue; } for (int index = 0; index < classes.length; index++) { // 如果参数类型是请求和响应的http,则不需要拼接【这两个参数,使用JSON.toJSONString()转换会抛异常】 if (args[index] instanceof HttpServletRequest || args[index] instanceof HttpServletResponse) { continue; } requestBuilder.append(args[index] == null ? "" : JSON.toJSONString(args[index])); } recordMessage.setRequestParames(requestBuilder.toString()); } return; }
