== 单元测试应用示例——测试工具类 ==
工具类cn.com.pcgames.gamehall2.util.SqlHelper是游戏大厅DAO层辅助工具类.例如:SqlHelper.buildInsert(List<FieldDesc> fields, String tablename,String[] excludes);[[BR]]
根据数据库表元信息，表名生成sql插入语句,使用示例代码如cn.com.pcgames.gamehall2.repository.impl.GameDAOImpl[[BR]]

{{{ #!java
   public class GameDAOImpl extends AbstractRepository<Game> implements GameDAO {

	private  List<FieldDesc> tableFields;

	public void setTableFields(List<FieldDesc> tableFields) {
		this.tableFields = tableFields;
	}

	public void init() {
		this.tableFields = SqlHelper.listFields(simpleJdbcTemplate, "game");
	}

	public GameDAOImpl() {
		super(Game.class);
	}

	public long createGame(Game game) {
		long gameId = idGenerator.generate("game", "gameId");
		game.setGameId(gameId);
                //SqlHelper生成插入语句
		String sql = SqlHelper.buildInsert(tableFields, "game", null);
		Object[] params = SqlHelper.getParameters(game, tableFields, null);
		int result = simpleJdbcTemplate.update(sql, params);

		return result == 1 ? gameId : 0;
	}
        
       ......
     }
