Why does running the interface return no value?

Problem scenario:

co-develop a project with a colleague, call the interface developed by it, but no return value is received

Problem analysis:

Copy SQL and add the specified query conditions, the SQL is correct, the problem is located in the MyBatis syntax

Problem solving:

1. Select field part Use *, resulting in no mapping between the field in the table and the PO class select *
is
changed to select the specific field

2. The parameter type is
incorrect Criticizing others for a small mistake, everyone has come from that stage, and has made such mistakes in the past. To sum up, although I do not make such mistakes at present
