Mybatis will report an error when inserting multiple entries with foreach, but one will be fine, saying that there is a format error.

this is the xml file:

the following error:

you should use the connection pool of druid. The visual problem is the version of druid:
sql does not have Comment, throwing exception syntax error, COMMA values
upgrade druid to see if it can be written well


values. It is not a sql standard function. All I know is mysql support.
