### Question:
GroupDao extends BaseDao { public DasGroup getGroupByName(String name) throws SQLException { String sql = "select id, group_name, group_comment, update_user_no, insert_time from dal_group where group_name = '" + name + "' limit 1"; List<DasGroup> list = this.queryBySql(sql, DasGroup.class); return CollectionUtils.isNotEmpty(list) ? list.get(0) : null; }  Long insertDasGroup(DasGroup group); int initAdminGroup(DasGroup group); int updateDalGroup(DasGroup group); int deleteDalGroup(Long groupId); Long getCountByName(String name); Long getCountByIdAndName(Long id, String name); List<DasGroup> getGroupsByUserId(Long user_id); DasGroup getGroupsByDbSetId(Long dbsetId); DasGroup getDalGroupById(Long id); DasGroup getGroupByName(String name); List<DasGroup> getAllGroups(); List<DasGroup> getAllGroupsByAppoid(String appid); List<DasGroup> getAllGroupsWithNotAdmin(); Long getTotalCount(Paging<DasGroup> paging); List<DalGroupView> findGroupPageList(Paging<DasGroup> paging);  }### Answer:
@Test public void getGroupByName() throws Exception { DasGroup dasGroup = groupDao.getGroupByName("das_test"); System.out.println("getGroupByName :-------> " + dasGroup); Assert.assertTrue(dasGroup != null); }
