页面是一个table，我之前写了关于如何拿table中多条数据的文章,这里就不过多的去写了。
直接写后台处理：
controller:
EXCEL:
public void exportExcel (HttpServletResponse response,Map totaltablestr,JSONArray storyboardstr) {
String fileName = "串联单";
try {
String name = "串联单";
String[] columnName = { "序号", "类别", "标题", "状态/内容","文字长度","总字数"};
// List<Map<String,Object>> excelList = queryScoreCount(unitId,columnId,userId,from,to,logonUser);
// List<Map<String,Object>> total = totalCount(storyboardstr);
// excelList.add(total.get(0));
int columnNumber = 6;
// 第一步，创建一个webbook，对应一个Excel文件
XSSFWorkbook wb = new XSSFWorkbook();
// 第二步，在webbook中添加一个sheet,对应Excel文件中的sheet
XSSFSheet sheet = wb.createSheet(name);
sheet.setDefaultColumnWidth(15); //统一设置列宽
// 创建第0行 也就是标题
XSSFRow rowTitle = sheet.createRow(0);
rowTitle.setHeightInPoints(50);// 设备标题的高度
// 第三步创建标题的单元格样式titleStyle以及字体样式titleFont
XSSFCellStyle titleStyle = wb.createCellStyle();
titleStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);
titleStyle.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);
titleStyle.setFillForegroundColor(HSSFColor.LIGHT_TURQUOISE.index);
titleStyle.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
XSSFFont titleFont = wb.createFont(); // 创建字体样式
titleFont.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); // 字体加粗
titleFont.setFontName("黑体"); // 设置字体类型
titleFont.setFontHeightInPoints((short) 15); // 设置字体大小
titleStyle.setFont(titleFont); // 为标题样式设置字体样式
XSSFCell cell1 = rowTitle.createCell(0);// 创建标题第一列
sheet.addMergedRegion(new CellRangeAddress(0,0,0,columnNumber - 1)); // 合并列标题
cell1.setCellValue(name); // 设置值标题
cell1.setCellStyle(titleStyle); // 设置标题样式
// 创建第1行 也就是表头
XSSFRow row = sheet.createRow(1);
row.setHeightInPoints(37);// 设置表头高度
// 第四步，创建表头单元格样式 以及表头的字体样式
XSSFCellStyle style = wb.createCellStyle();
style.setWrapText(true);// 设置自动换行
style.setAlignment(HSSFCellStyle.ALIGN_CENTER);
style.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER); // 创建一个居中格式
style.setBottomBorderColor(HSSFColor.BLACK.index);
style.setBorderBottom(HSSFCellStyle.BORDER_THIN);
style.setBorderLeft(HSSFCellStyle.BORDER_THIN);
style.setBorderRight(HSSFCellStyle.BORDER_THIN);
style.setBorderTop(HSSFCellStyle.BORDER_THIN);
XSSFFont headerFont = wb.createFont(); // 创建字体样式
headerFont.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); // 字体加粗
headerFont.setFontName("黑体"); // 设置字体类型
headerFont.setFontHeightInPoints((short) 10); // 设置字体大小
style.setFont(headerFont); // 为标题样式设置字体样式
// 第四.一步，创建表头的列
for (int i = 0; i < columnNumber; i++) {
XSSFCell cell = row.createCell(i);
cell.setCellValue(columnName[i]);
cell.setCellStyle(style);
}
// 第五步，创建单元格，并设置值
for (int i = 0; i < storyboardstr.size(); i++) {
Map map = (Map) storyboardstr.get(i);
row = sheet.createRow(i + 2);
// 为数据内容设置特点新单元格样式1 自动换行 上下居中
XSSFCellStyle xssfCellStyle = wb.createCellStyle();
xssfCellStyle.setWrapText(true);// 设置自动换行
xssfCellStyle.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER); // 创建一个居中格式
// 设置边框
xssfCellStyle.setBottomBorderColor(HSSFColor.BLACK.index);
xssfCellStyle.setBorderBottom(HSSFCellStyle.BORDER_THIN);
xssfCellStyle.setBorderLeft(HSSFCellStyle.BORDER_THIN);
xssfCellStyle.setBorderRight(HSSFCellStyle.BORDER_THIN);
xssfCellStyle.setBorderTop(HSSFCellStyle.BORDER_THIN);
XSSFCell datacell;
for (int j = 0; j < columnNumber; j++) {
datacell = row.createCell(j);
switch (j) {
case 0:
datacell.setCellValue(map.get("sequence").toString());
break;
case 1:
datacell.setCellValue(map.get("sort").toString());
break;
case 2:
datacell.setCellValue(map.get("headline").toString());
break;
case 3:
datacell.setCellValue(map.get("matter").toString());
break;
case 4:
datacell.setCellValue(map.get("articlelength").toString());
break;
case 5:
datacell.setCellValue(map.get("scontext").toString());
break;
}
datacell.setCellStyle(xssfCellStyle);
}
}
XSSFCellStyle xssfCellStyle = wb.createCellStyle();
xssfCellStyle.setBottomBorderColor(HSSFColor.BLACK.index);
xssfCellStyle.setBorderBottom(HSSFCellStyle.BORDER_THIN);
xssfCellStyle.setBorderLeft(HSSFCellStyle.BORDER_THIN);
xssfCellStyle.setBorderRight(HSSFCellStyle.BORDER_THIN);
xssfCellStyle.setBorderTop(HSSFCellStyle.BORDER_THIN);
row = sheet.createRow(storyboardstr.size()+2);
XSSFCell datacell = row.createCell(0);
datacell.setCellValue(totaltablestr.get("name").toString());
datacell.setCellStyle(xssfCellStyle);
datacell = row.createCell(1);
datacell.setCellStyle(xssfCellStyle);
datacell = row.createCell(2);
datacell.setCellStyle(xssfCellStyle);
datacell = row.createCell(3);
datacell.setCellStyle(xssfCellStyle);
datacell = row.createCell(4);
datacell.setCellValue(totaltablestr.get("times").toString());
datacell.setCellStyle(xssfCellStyle);
datacell = row.createCell(5);
datacell.setCellValue(totaltablestr.get("totals").toString());
datacell.setCellStyle(xssfCellStyle);
// 第六步，将文件存到浏览器设置的下载位置
String filename = fileName + ".xlsx";
response.setContentType("application/ms-excel;charset=UTF-8");
response.setHeader("Content-Disposition", "attachment;filename="
.concat(String.valueOf(URLEncoder.encode(filename, "UTF-8"))));
OutputStream out = response.getOutputStream();
wb.write(out);// 将数据写出去
out.close();
String str = "导出" + fileName + "成功！";
System.out.println(str);
} catch (Exception e){
e.printStackTrace();
String str1 = "导出" + fileName + "失败！";
System.out.println(str1);
}
}
TXT:
public void exportTxt (HttpServletResponse response,Map totaltablestr,JSONArray storyboardstr) {
String fileName = "文稿及稿件统计.txt";
String tab = "\t\t";
String enter = "\r\n";
try {
response.setContentType("text/plain");// 一下两行关键的设置
response.setHeader("Content-Disposition", "attachment;filename="
.concat(String.valueOf(URLEncoder.encode(fileName, "UTF-8"))));// filename指定默认的名字
OutputStreamWriter osw = new OutputStreamWriter(response.getOutputStream(), StandardCharsets.UTF_8);
BufferedWriter bw = new BufferedWriter(osw);
StringBuilder newStr = new StringBuilder();
newStr.append("【序号】"+"\t").append(tab);
newStr.append("【类别】"+"\t\t").append(tab);
newStr.append("【标题】"+"\t\t").append(tab);
newStr.append("【状态/内容】"+"\t\t").append(tab);
newStr.append("【文字长度】"+"\t").append(tab);
newStr.append("【总字数】").append(enter);
int length = 40;
for (int i = 0; i < storyboardstr.size(); i++) {
Map map = (Map) storyboardstr.get(i);
newStr.append(appendStr4Length(map.get("sequence").toString(), length));
newStr.append(appendStr4Length(map.get("sort").toString(),length)).append(tab);
newStr.append(appendStr4Length(map.get("headline").toString(),length)).append(tab);
newStr.append(appendStr4Length(map.get("matter").toString(),length)).append(tab);
newStr.append(appendStr4Length(map.get("articlelength").toString(),length)).append(tab);
newStr.append(appendStr4Length(map.get("scontext").toString(),length)).append(enter);
}
newStr.append(appendStr4Length("【合计】", length)).append(tab);
newStr.append(appendStr4Length("",length)).append(tab);
newStr.append(appendStr4Length("",length)).append(tab);
newStr.append(appendStr4Length("",length)).append(tab);
newStr.append(appendStr4Length(totaltablestr.get("times").toString(),length)).append(tab);
newStr.append(appendStr4Length(totaltablestr.get("totals").toString(),length)).append(enter);
bw.write(newStr.toString()); //向新生的文件写入行数据
bw.newLine();//换行
bw.flush();
bw.close();
} catch (Exception e) {
e.printStackTrace();
}
}
private static String appendStr4Length(String str, int length){
if(str == null){
str = "";
}
try {
int strLen = 0;//计算原字符串所占长度,规定中文占两个,其他占一个
for(int i = 0 ; i<str.length(); i++){
if(isChinese(str.charAt(i))){
strLen = strLen + 2;
}else{
strLen = strLen + 1;
}
}
if(strLen>=length){
return str;
}
int remain = length - strLen;//计算所需补充空格长度
StringBuilder strBuilder = new StringBuilder(str);
for(int i = 0; i< remain ; i++){
strBuilder.append(" ");
}
str = strBuilder.toString();
} catch (Exception e) {
e.printStackTrace();
}
return str;
}
private static boolean isChinese(char c) {
Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
return ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
|| ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B
|| ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
|| ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS
|| ub == Character.UnicodeBlock.GENERAL_PUNCTUATION;
}
这里excel的格式可以根据自己的需求进行更改，我这里在表格下加了单独一行的合计。不需要的可以去掉。
txt的样式也可以更改。
