報錯原因: 後臺的異常攔截器對handel類型轉換失敗造成的:
解決辦法在handel轉換前進行判斷:
if(o instanceof HandlerMethod){
String methodName = ((HandlerMethod) o).getMethod().getName();
String className = ((HandlerMethod)o).getBeanType().getSimpleName();
logger.error("異常信息>>>>>ClassName:"+className+".....method:"+methodName+".....",e);
}
