@Service
public class DeptServiceImpl extends ServiceImpl<DeptMapper, Dept>
        implements DeptService {
    @Resource
    private DeptMapper mapper;
    @Cacheable(value = "cacheSpace" ,key="#deptno")
    @Override
    public Dept getByDeptCode(Integer deptno) {
        return mapper.getByDeptCode(deptno);
    }
}
