解决 Cause: org.postgresql.util.PSQLException: ERROR: null value in column "time_period" violates no

postgre添加数据时出现如下错误

### Cause: org.postgresql.util.PSQLException: ERROR: null value in column "time_period" violates not-null constraint
; SQL []; ERROR: null value in column "time_period" violates not-null constraint; nested exception is org.postgresql.util.PSQLException: ERROR: null value in column "time_period" violates not-null constraint

根据 null value in column "time_period" violates not-null constraint 说明time_period字段不能为空

插入数据时没有给time_period传值所以才出现此类错误
