在线查询数据time类型转换错误

[jdj199222]

在线查询数据功能,如果查询select * from table 时候报如下错误.

精确定位后发现,是字段数据类型为time时候就会报错. 日志显示入下 [2018-07-31 11:36:51,927][MainThread:140477748217600][task_id:default][exception_logging_middleware.py:10] [ERROR]- Traceback (most recent call l ast): File "/data/archer/sql/extend_json_encoder.py", line 52, in default return convert(obj) File "/data/venv4archer/lib/python3.6/functools.py", line 803, in wrapper return dispatch(args[0].class)(*args, **kw) File "/data/archer/sql/extend_json_encoder.py", line 26, in convert raise TypeError('can not convert type') TypeError: can not convert type
