准备工作
创建word模板.docx文件
使用模板操作，因为自己使用poi去写word过于麻烦，耦合性太高
${XXX}理解成占位符，会替换为填充的数据，可配置为其他比如*{xxx}*
编写模板格式.xml文件
创建的.docx文件顺序基本是乱的，需要另存为.xml格式手动更改格式
用编译器打开(我用的IDEA)找到要替换的占位符的位置
把所有要替换的位置都找到改为一行
以此类推改完所有替换内容的标识
改完之后在改成.docx格式
java上手poi

使用到的包
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;import org.apache.poi.xwpf.usermodel.*;import org.openqa.selenium.JavascriptExecutor;import org.openqa.selenium.OutputType;import org.openqa.selenium.TakesScreenshot;import org.openqa.selenium.phantomjs.PhantomJSDriver;import org.openqa.selenium.phantomjs.PhantomJSDriverService;import org.openqa.selenium.remote.DesiredCapabilities;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Service;import org.springframework.util.CollectionUtils;import org.springframework.util.StringUtils;import javax.servlet.ServletOutputStream;import javax.servlet.http.HttpServletResponse;import java.io.*;import java.text.DecimalFormat;import java.util.*;import java.util.List;import java.util.concurrent.TimeUnit;import java.util.stream.Collectors;
具体应用
/*** 读取模板* @param HttpServletResponse * @throws Exception*/public void operatorWord(HttpServletResponse response) throws Exception {//获得模板文件InputStream docis = new FileInputStream("C:\Users\16630\Desktop\模板A.docx");//转成wordCustomXWPFDocument document = new CustomXWPFDocument(docis);//写入图片this.insertImage(document);//写入表格this.insertTable(document);//段落替换对象this.insertText(document)//把doc输出到输出流response.setCharacterEncoding("UTF-8");response.setContentType("application/msword");//文件名String fileName = "考试成绩分析" + htmlDataTime.getStartData();response.setHeader("Content-Disposition", "attachment;fileName="+ new String(fileName.getBytes("UTF-8"),"ISO-8859-1"));ServletOutputStream responseOutputStream = response.getOutputStream();document.write(responseOutputStream);responseOutputStream.flush();responseOutputStream.close();in.close();}
对应封装方法 ----------图片插入指定位置操作
/*** 写入图片在word中* @param document* @throws IOException* @throws InvalidFormatException*/private void insertImage(CustomXWPFDocument document) throws IOException, InvalidFormatException {//图片FileInputStream in = new FileInputStream(new("C:\Users\16630\Desktop\image.jpg"));//段落集合List<XWPFParagraph> paragraphs = document.getParagraphs();for (XWPFParagraph paragraph : paragraphs) {//获取到段落中的所有文本内容String text = paragraph.getText();//判断此段落中是否有需要进行替换的文本if (WordUtil.checkText(text)) {List<XWPFRun> runs = paragraph.getRuns();for (XWPFRun run : runs) {//替换模板原来位置String key = "${image}";if (run.toString().indexOf(key) != -1) {byte[] ba = new byte[in.available()];int len = in.read(ba);ByteArrayInputStream byteInputStream = new ByteArrayInputStream(ba, 0, len);//设置图片document.addPictureData(byteInputStream, XWPFDocument.PICTURE_TYPE_PNG);//创建一个word图片，并插入到文档中-->像素可改document.createPicture(document.getAllPictures().size() - 1, 240, 240,paragraph);}break;}break;}}}
图片操作使用到的工具类

对应封装方法 ----------表格操作
private void insertTable(CustomXWPFDocument document) {//创建表格接受参数-->外层list是行内层是列List<List<String>> tableList = new ArrayList();List<String> cells = new ArrayList<>();cells.add("1");cells.add("张三");cells.add("100");tableList.add(cells);List<String> cellList = new ArrayList<>();cellList.add("2");cellList.add("李四");cellList.add("10");tableList.add(cellList);//获取表格位置List<XWPFTable> tables = document.getTables();WordUtil.insertTable(tables.get(0),tableList);}
表格操作用到的工具类
/*** 为表格插入数据，行数不够添加新行** @param table需要插入数据的表格* @param tableList 插入数据集合*/public static void insertTable(XWPFTable table, List<List<String>> tableList) {//创建行,根据需要插入的数据添加新行，不处理表头for (int i = 1; i <= tableList.size(); i++) {table.createRow();}//遍历表格插入数据List<XWPFTableRow> rows = table.getRows();for (int i = 1; i < rows.size(); i++) {XWPFTableRow newRow = table.getRow(i);List<XWPFTableCell> cells = newRow.getTableCells();for (int j = 0; j < cells.size(); j++) {XWPFTableCell cell = cells.get(j);cell.setText(tableList.get(i - 1).get(j));//表格样式一致-->没有此段表格会默认左对齐//有此段会使表格格式一致CTTc cttc = cell.getCTTc();CTTcPr ctPr = cttc.addNewTcPr();ctPr.addNewVAlign().setVal(STVerticalJc.CENTER);cttc.getPList().get(0).addNewPPr().addNewJc().setVal(STJc.CENTER);}}}
对应封装方法 ----------段落内容替换操作
private void insertText(CustomXWPFDocument document) {//声明替换模板对象Map textMap = new HashMap();textMap.put("${maxName}","张三");textMap.put("${maxScore}", "100");textMap.put("${minName}","李四");textMap.put("${minScore}", "10");//替换模板数据WordUtil.changeText(document,textMap);}
段落内容操作用到的工具类
/*** 替换段落文本** @param document docx解析对象* @param textMap 需要替换的信息集合*/public static void changeText(XWPFDocument document, Map<String, Object> textMap) {//获取段落集合List<XWPFParagraph> paragraphs = document.getParagraphs();for (XWPFParagraph paragraph : paragraphs) {//获取到段落中的所有文本内容String text = paragraph.getText();//判断此段落中是否有需要进行替换的文本if (checkText(text)) {List<XWPFRun> runs = paragraph.getRuns();for (XWPFRun run : runs) {//替换模板原来位置run.setText(changeValue(run.toString(), textMap), 0);}}}}/*** 判断文本中是否包含$** @param text 文本* @return 包含返回true, 不包含返回false*/public static boolean checkText(String text) {boolean check = false;if (text.indexOf("$") != -1) {check = true;}return check;}/*** 替换模板${}*/private static Object changeValue(String value, Map<String, Object> textMap) {Set<Map.Entry<String, Object>> textSets = textMap.entrySet();Object valu = "";for (Map.Entry<String, Object> textSet : textSets) {// 匹配模板与替换值 格式${key}String key = textSet.getKey();if (value.contains(key)) {valu = textSet.getValue();}}return valu;}
效果图
如果想设置单独的样式
比如加颜色、居中等，要确保.xml中替换单位为一行
