小心查看dao，发现画蛇添足了
@Service
public interface AttendanceDao extends CrudRepository<com.cd.moa.entity.OaAttendance, Long> {
@Transactional(readOnly = true)
Page<OaAttendance> findByUsername(String name, Pageable pageable);

@Transactional(readOnly = true)
List<OaAttendance> findByUsername(String name);

}

把@Service
@Transactional(readOnly = true)
@Transactional(readOnly = true)
全去掉，改为：
public interface AttendanceDao extends CrudRepository<com.cd.moa.entity.OaAttendance, Long> {

Page<OaAttendance> findByUsername(String name, Pageable pageable);

List<OaAttendance> findByUsername(String name);

}
解决！！！
