The error message indicates that there is an ambiguity in the SQL query in the 'StaffMapper.xml' file. Specifically, the 'staffid' column in the WHERE clause is ambiguous, meaning that it is not clear which table's 'staffid' column should be used.

To resolve this issue, you need to specify the table from which the 'staffid' column should be used in the WHERE clause. You can do this by prefixing the 'staffid' column with the table name or table alias.

For example, if the 'staffid' column belongs to the 'staff' table, you can modify the SQL query as follows:

SELECT count(0) FROM ( SELECT staff.staffid, staff.staffname, staff.idcard, staff.address, staff.phone, staff.entrytime, staff.leavetime, staff.state, branch.branchname, department.deptname, role.rolename FROM staff JOIN branch ON staff.branchid = branch.branchid JOIN department ON staff.deptid = department.deptid JOIN role ON staff.roleid = role.roleid WHERE staff.staffid = ? LIKE CONCAT('%',?,'%') AND staff.state = 0 ) tmp_count
