Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'permissionid' cannot be null

The error may involve boot.spring.mapper.RoleMapper.addRolePermission-Inline

The error occurred while setting parameters

SQL: insert into role_permission(roleid,permissionid) values (?,?)
