本次要做一个小工具，读取excel数据，然后生成word文件。

直接上代码：

一、引用包

java">        <dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.15</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.15</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId><version>3.15</version></dependency>

二、工具类 WordUtils

java">package com.example.maitou;import org.apache.poi.xwpf.usermodel.*;import java.util.Iterator;
import java.util.List;
import java.util.Map;public class WordUtils {/**** @Description :替换段落文本* @param document docx解析对象* @param textMap  需要替换的信息集合* @return void*/public static void changeText(XWPFDocument document, Map<String, Object> textMap) {// 获取段落集合Iterator<XWPFParagraph> iterator = document.getParagraphsIterator();XWPFParagraph paragraph = null;while (iterator.hasNext()) {paragraph = iterator.next();// 判断此段落是否需要替换if (checkText(paragraph.getText())) {replaceValue(paragraph, textMap);}}}/**** @Description :替换表格内的文字* @param document* @param data* @return void*/public static void changeTableText(XWPFDocument document, Map<String, Object> data) {// 获取文件的表格Iterator<XWPFTable> tableList = document.getTablesIterator();XWPFTable table;List<XWPFTableRow> rows;List<XWPFTableCell> cells;// 循环所有需要进行替换的文本，进行替换while (tableList.hasNext()) {table = tableList.next();if (checkText(table.getText())) {rows = table.getRows();// 遍历表格，并替换模板for (XWPFTableRow row : rows) {cells = row.getTableCells();for (XWPFTableCell cell : cells) {// 判断单元格是否需要替换if (checkText(cell.getText())) {List<XWPFParagraph> paragraphs = cell.getParagraphs();for (XWPFParagraph paragraph : paragraphs) {replaceValue(paragraph, data);}}}}}}}/**** @Description :检查文本中是否包含指定的字符(此处为“$”)* @param text* @return boolean*/public static boolean checkText(String text) {boolean check = false;if (text.contains("$")) {check = true;}return check;}/**** @Description :替换内容* @param paragraph* @param textMap* @return void*/public static void replaceValue(XWPFParagraph paragraph, Map<String, Object> textMap) {XWPFRun run, nextRun;String runsText;List<XWPFRun> runs = paragraph.getRuns();for (int i = 0; i < runs.size(); i++) {run = runs.get(i);runsText = run.getText(0);if (runsText.contains("${") || (runsText.contains("$") && runs.get(i + 1).getText(0).substring(0, 1).equals("{"))) {while (!runsText.contains("}")) {nextRun = runs.get(i + 1);runsText = runsText + nextRun.getText(0);//删除该节点下的数据paragraph.removeRun(i + 1);}Object value = changeValue(runsText, textMap);//判断key在Map中是否存在String replaceText = runsText.replace("${", "").replace("}", "");if (textMap.containsKey(replaceText)) {run.setText(value.toString(), 0);} else {//如果匹配不到，则不修改run.setText(runsText, 0);}}}}/**** @Description :匹配参数* @param value* @param textMap* @return java.lang.Object*/public static Object changeValue(String value, Map<String, Object> textMap) {Object valu = "";for (Map.Entry<String, Object> textSet : textMap.entrySet()) {// 匹配模板与替换值 格式${key}String key = textSet.getKey();if (value.contains(key)) {valu = textSet.getValue();}}return valu;}
}

main方法

java">public class WordTextTest {public static void main(String[] args) throws IOException {WordTextTest.fillWord();}public static void fillWord() throws IOException {//文件模板输入流InputStream inputStream = new ClassPathResource("document/demo2.docx").getInputStream();XWPFDocument document = new XWPFDocument(inputStream);Map<String, Object> map = new HashMap<>();map.put("title", "标题");map.put("name", "_小半q");map.put("sex", "男");if (map1.size() > 0) {// 替换掉表格之外的文本(仅限文本)WordUtils.changeText(document, map);// 替换表格内的文本对象WordUtils.changeTableText(document, map);}FileOutputStream fos = new FileOutputStream("C:\\Users\\MHGIS\\Desktop\\text1" + ".docx");document.write(fos);}
}

四、模板：
