针对java操作word,大家有不懂的可以在评论区留言。
前言
最近做项目要用到word导出和导入,从网上找资料,发现都是一些零零散散的碎片,不能一步到位,经过项目的论证,站到业务和技术的角度,写一篇java通过poi,自定义word模板,对word文档内容进行替换,对文档中表格进行填充,特殊表格的复制、添加图片,希望对各读者有用😁。
maven引用:
作者使用的是4.1.2版本的poi,如果项目中使用的easyexcel,需要解决jar包冲突。
<properties>
<poi.version>4.1.2</poi.version>

<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>

识别word中上标、下标
在工具类中添加以下代码
// 识别word中上标、下标
public List<String> getTextsBySubAndSup() {
List<String> list = new ArrayList<>();
List<XWPFParagraph> paras = xwpfDocument.getParagraphs();
Iterator<XWPFParagraph> paragraphsIterator = xwpfDocument.getParagraphsIterator();
while (paragraphsIterator.hasNext()){
String text = "";
XWPFParagraph next = paragraphsIterator.next();
for (XWPFRun xwrun : next.getRuns()) {
VerticalAlign subscript = xwrun.getSubscript();
String smalltext = xwrun.getText(0);
switch (subscript) {
case BASELINE:
// 正常文本
text += smalltext;
break;
case SUBSCRIPT:
// 下标
text += "<sub>" + smalltext + "</sub>";
break;
case SUPERSCRIPT:
// 上标
text += "<sup>" + smalltext + "</sup>";
break;
}
}
if(null != text && !"".equals(text)){
list.add(text);
}
}
return list;
}
示例:
代码识别后结果:
通过富文本解析即可实现需求。
导出测试类:
// word模板名称
private static String temName = "apiTemplate.docx";
public static void main(String[] args) throws NoSuchFieldException {
// 测试数据
Map m = new HashMap<>();
m.put("APINAME", "测试导出word");
m.put("year", "2023");
m.put("month", "02");
m.put("day", "22");
m.put("APIPATH", "/test");
m.put("remark", "11");
List<Map<String, String>> list = new ArrayList<>();
for(int i = 0; i < 5; i++){
Map map = new HashMap();
map.put("a", "1" + i);
map.put("b", "2" + i);
map.put("c", "3" + i);
map.put("d", "4" + i);
list.add(map);
}
// word工具类 下文提供工具类代码
WordReporterUtils wordReporter = new WordReporterUtils();
try {
// 初始化模板,调用执行方法前必须调用初始化方法
wordReporter.init("模板路径" + temName);
// 普通文本替换
wordReporter.exportText(m);
/**
* 特殊表格赋值
* text:文本值
* x:行下标
* y:列下标
* tablIndex:表格下标
* fontSize: 文字大小
*/
wordReporter.changeTableProvince("我终于输出了", 1, 1,0, 16);
/**
* @param params 循环输入表格数据
* @param x 模板行
* @param tableIndex 表格下标
*/
wordReporter.exportTable(list, 1, 1);
// 生成文件,最后调用
wordReporter.generate("D:\\file\\word\\a.docx");
} catch (Exception e) {
throw new RuntimeException(e);
}
System.out.println("执行完毕");
}
导入测试类:
poi识别文档中的行与可见行是有区别的,举个例子。
没有手动换行还是属于一行,没有手动换行还是属于一行,没有手动换行还是属于一行,没有手动换行还是属于一行,没有手动换行还是属于一行,没有手动换行还是属于一行。
这是单独的一行
这是
单独的一行
如上述例子,通过下方的测试类在识别文档文字时,序号1,2,3,4分别为行,既是序号1的内容太长,在识别中还是属于一行。
public static void main(String[] args) throws NoSuchFieldException {
String filePath = "导入的文档路径";
WordReporterUtils wordReporter = new WordReporterUtils();
try {
// 初始化模板
wordReporter.init(filePath);
// 获取文档所有的文字
List<String> texts = wordReporterUtils.getPictureText();
/**
* texts是word中所有的文字
*/
} catch (Exception e) {
throw new RuntimeException(e);
}
System.out.println("执行完毕");
}
