读取Excel表格（数据为树形）

数据的代码按树形结构编码，每行数据有三列，code、name、description，每条数据可行占到多行，即name和description可能多行，但code只会占一行。

ResouceClassDao dao = new ResouceClassDaoImpl();

	public RowObj readSheetAndInsert(Sheet st, int typeId)
			throws BiffException, IOException {
		int rows = st.getRows();

		Stack<RowObj> parentObjs = new Stack<RowObj>();
		RowObj curParentObj = new RowObj();

		int count = 0;
		// 读取excel数据
		for (int i = 0; i < rows; i++) {
			Cell cell = st.getCell(0, i);
			String code = cell.getContents().trim();

			if (code != null && code.length() > 0) {
				cell = st.getCell(1, i);
				String name = cell.getContents().trim();

				cell = st.getCell(2, i);
				String description = cell.getContents().trim();

				RowObj obj = new RowObj();
				obj.setTypeId(typeId);
