AOP攔截日志類，拋異常：java.lang.IllegalStateException: It is illegal to call this method if the current request is not in asynchronous mode

 

AOP的日志攔截類中，拋出異常：

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

主要原因：對方法的參數使用JSON.toJSONString(args[index])轉換時，有異常拋出【如果參數類型是請求和響應的http，使用JSON.toJSONString()轉換會拋異常】

解決方案：將不能進行序列化的入參過濾掉，只要留下我們需要記錄的入參參數記錄到日志中即可
