poi导出word表格的操作讲解

时间：2020-09-30 13:00:30|栏目：JAVA代码|点击： 次

一、效果如下

二、js代码

function export_word(){ //导出word
  var url = "czzsca/exportWord.do";
  this.export(url);
}
function export(url){
  var currentyear = $("#mainYear").val() * 1;
  var key_columns = ['xh',"d_name","d_unit","d_number","d_estimate","d_lastyear","jnjh","d_remarks","d_depart","d_executeunit"];
  var value_columns = ['序号','项目名称','单位','数量','总概算','至'+(currentyear-1)+'年完成',currentyear+'年计划','附注','责任部门','计划执行单位'];
  window.location.href= url+"?key_columns="+key_columns+"&value_columns="+value_columns+"&title="+currentyear+"年 更新改造计划 正式计划草案";
}

三、controller代码

（controller代码比较长，主要是格式化每一行的数据，主要是往工具类里传List<List<String>>参数，泛型的List<String>是每一行，String是每一列）

 //导出word
 @RequestMapping("/exportWord.do")
 @ResponseBody
 public ReturnMsg exportWord(String[] key_columns,String[] value_columns,String title,HttpServletResponse response){
 ReturnMsg rm = new ReturnMsg();
 try {
  response.setCharacterEncoding("UTF-8");
     response.setContentType("application/msexcle");  
     response.setHeader("content-disposition", "attachment;filename="+new String("正式计划草案".getBytes("gb2312"),"ISO8859-1")+".doc");
     List<List<String>> content = new ArrayList<List<String>>();

     String trimpro = new BigDecimal(this.map.get("tzjh")==null||"".equals(this.map.get("tzjh")+"")?"0":this.map.get("tzjh")+"").setScale(1, RoundingMode.UP)+"";
     String temp = new BigDecimal(trimpro).subtract(new BigDecimal(jnjhzh))+"";
     if("0".equals(temp)) {
     temp = "";
     }
     head = ExportUtil.getCzzscaList(jnjhzh, trimpro, temp);
     Map dounit = new HashMap();
     dounit.put("dwlx", 0);

五、详解：

1.设置纸张大小

（1）创建完XWPFDocument后，默认为A4纸张，如需调整纸张大小，这里我是要用A3大小使用如下代码

XWPFDocument doc= new XWPFDocument();
CTDocument1 document = doc.getDocument(); 
CTBody body = document.getBody(); 
if(!body.isSetSectPr()){ 
  body.addNewSectPr(); 
} 
CTSectPr section = body.getSectPr(); 
 
if(!section.isSetPgSz()){ 
  section.addNewPgSz(); 
} 
CTPageSz pageSize = section.getPgSz(); 
pageSize.setW(BigInteger.valueOf(15840));
pageSize.setH(BigInteger.valueOf(12240));
pageSize.setOrient(STPageOrientation.LANDSCAPE);

（2）默认A4纸张大小的话只用XWPFDocument

XWPFDocument doc= new XWPFDocument();

（3）使用CTPageSz类需要导入ooxml-schemas的jar包（所有需要的jar包maven依赖在底部）

2.单元格列宽度

（1）每一列宽度相等自适应，不需单独设置每一列宽度的话使用如下代码

//表格
XWPFTable ComTable = doc.createTable();
//表格自适应宽度
CTTblWidth comTableWidth = ComTable.getCTTbl().addNewTblPr().addNewTblW();
comTableWidth.setType(STTblWidth.DXA);
comTableWidth.setW(BigInteger.valueOf(9072));

（2）单独设置每列宽度

//表格
XWPFTable ComTable = doc.createTable();   
//设置指定宽度
CTTbl ttbl = ComTable.getCTTbl(); 
CTTblGrid tblGrid = ttbl.addNewTblGrid();
int[] colWidths = new int[] { 600, 3000, 500, 500, 800, 800 ,800,3000,800,1500}; 
for (int i : colWidths) {
  CTTblGridCol gridCol = tblGrid.addNewGridCol(); 
  gridCol.setW(new BigInteger(i+"")); 
}

（3）使用CTTblGrid类需要导入poi-ooxml-schemas的jar包（所有需要的jar包maven依赖在底部）

3.单元格内字体样式

（1）不需要设置单元格字体

for (int i = 0; i < rows; i++) {
  XWPFTableRow rowsContent = ComTable.createRow();
  for (int j = 0; j < list.get(i).size(); j++) {  
    rowsContent.getCell(j).setText(list.get(i).get(j)+""); //用单元格加载内容
  }
}

（2）设置单元格内字体字号、是否加粗

for (int i = 0; i < rows; i++) {
  XWPFTableRow rowsContent = ComTable.createRow();
  for (int j = 0; j < list.get(i).size(); j++) {
    XWPFParagraph cellParagraphC = rowsContent.getCell(j).getParagraphs().get(0);
    if(j!=1&&j!=7) {
      cellParagraphC.setAlignment(ParagraphAlignment.CENTER); //设置表格内容居中
    }
    XWPFRun cellParagraphRunC = cellParagraphC.createRun();
    cellParagraphRunC.setFontSize(10); //设置表格内容字号
    cellParagraphRun.setBold(true); //设置表头单元格加粗
    cellParagraphRunC.setText(list.get(i).get(j)+""); //单元格段落加载内容
  }
}

4.单元格居中（水平居中、垂直居中）

（1）使用单元格加载内容

for (int i = 0; i < value_columns.length; i++) {
  XWPFTableCell cell = ComTable.getRow(0).getCell(i);
  cell.setVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER); //垂直居中
  CTTc cttc = cell.getCTTc();
  CTP ctp = cttc.getPList().get(0);
  CTPPr ctppr = ctp.getPPr();
  if (ctppr == null) {
    ctppr = ctp.addNewPPr();
  }
  CTJc ctjc = ctppr.getJc();
  if (ctjc == null) {
    ctjc = ctppr.addNewJc();
  }
  ctjc.setVal(STJc.CENTER); //水平居中
}

（2）使用单元格的段落加载内容，只用调用垂直居中的方法

for (int i = 0; i < value_columns.length; i++) {
  XWPFTableCell cell = ComTable.getRow(0).getCell(i);
  cell.setVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER); //垂直居中
}

水平居中在3-(2)里调用了段落的方法居中过了

cellParagraphC.setAlignment(ParagraphAlignment.CENTER);

5.单元格合并

（1）跨列合并单元格

public static void mergeCellsHorizontal(XWPFTable table, int row, int fromCell, int toCell) {
 for (int cellIndex = fromCell; cellIndex <= toCell; cellIndex++) {
  XWPFTableCell cell = table.getRow(row).getCell(cellIndex);
  if ( cellIndex == fromCell ) {  
  cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);
  } else {
  cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);
  }
 }
 }

（2）跨行合并单元格

public static void mergeCellsVertically(XWPFTable table, int col, int fromRow, int toRow) {
 for (int rowIndex = fromRow; rowIndex <= toRow; rowIndex++) {
  XWPFTableCell cell = table.getRow(rowIndex).getCell(col);
  if ( rowIndex == fromRow ) {
  cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);
  } else {
  cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);
  }
 }
 }

6.单元格内换行，单元格内使用\r换行没用，可以用addBreak方法

 for (int i = 0; i < list_vPostdutyNorm_parm.size(); i++) {
  row = ComTable.createRow();
  index++;
  for (int j = 0; j < list_vPostdutyNorm_parm.get(i).size(); j++) {
  if (j == 3 || j == 4) {
   cellParagraph.setAlignment(ParagraphAlignment.LEFT); //设置表头单元格居中
  } else {
   cellParagraph.setAlignment(ParagraphAlignment.CENTER); //设置表头单元格居中
  }
  String content = list_vPostdutyNorm_parm.get(i).get(j);
  cellParagraph = row.getCell(j).getParagraphs().get(0);
  cellParagraphRun = cellParagraph.createRun();
  cellParagraphRun.setFontSize(10); //设置表头单元格字号
  cellParagraphRun.setBold(false); //设置表头单元格加粗
  if (content.indexOf("\r") > -1) {
   String[] text = content.split("\r");
   for (int k = 0; k < text.length; k++) {
   if (k == 0) {
    cellParagraphRun.setText(text[k]);
   }else {
    cellParagraphRun.addBreak();
    cellParagraphRun.setText(text[k]);
   }
   }
  }else {
   cellParagraphRun.setText(content);
  }
  }
 }

六、使用到的Maven依赖

<dependency>
  <groupId>org.apache.xmlbeans</groupId>
  <artifactId>xmlbeans</artifactId>
  <version>2.6.0</version>
</dependency>
<dependency>
  <groupId>org.apache.poi</groupId>
  <artifactId>poi-ooxml</artifactId>
  <version>3.9</version>
</dependency>
<dependency>
  <groupId>org.apache.poi</groupId>
  <artifactId>ooxml-schemas</artifactId>
  <version>1.1</version>
</dependency>
<dependency>
  <groupId>org.apache.poi</groupId>
  <artifactId>poi-ooxml-schemas</artifactId>
  <version>3.16</version>
</dependency>
