问题
使用poi解析excel后，若为合并单元格，仅第一行有数据，后面的合并单元格没有数据；
解决办法
判断cell是否为合并单元格，之后分类处理
//判断是否为合并行if(isMergedRegion(sheet,j,0)){int lastRow = getRowNum(cras,sheet.getRow(i).getCell(0),sheet);for(;j<=lastRow;j++){Row row = sheet.getRow(j);if (row == null) {continue;}if (row.getFirstCellNum() < 0) {continue;}int readColumnCount = 0;if (columnCount == null || columnCount > row.getLastCellNum()) {readColumnCount = (int) row.getLastCellNum();} else {readColumnCount = columnCount;}List<Object> rowValue = new LinkedList<Object>();// 解析sheet 的列for (int k = 0; k < readColumnCount; k++) {if(isMergedRegion(sheet,j,k)) {rowValue.add(getMergedRegionValue(sheet, j, k));}else{Cell cell = row.getCell(k);rowValue.add(getCellValue(wb, cell));}}dataList.add(rowValue);}
获取合并单元格数据代码
/*** 获取合并单元格的值* @param sheet* @param row* @param column* @return*/public static String getMergedRegionValue(Sheet sheet, int row, int column){int sheetMergeCount = sheet.getNumMergedRegions();for(int i = 0 ; i < sheetMergeCount ; i++){CellRangeAddress ca = sheet.getMergedRegion(i);int firstColumn = ca.getFirstColumn();int lastColumn = ca.getLastColumn();int firstRow = ca.getFirstRow();int lastRow = ca.getLastRow();if(row >= firstRow && row <= lastRow){if(column >= firstColumn && column <= lastColumn){Row fRow = sheet.getRow(firstRow);Cell fCell = fRow.getCell(firstColumn);return getCellValue(fCell) ;}}}return null ;}
