[Java知识库]java实现word文档的编写

对于word文档的生成主要采用的poi生成。
引入依赖

<dependency>
   <groupId>org.apache.poi</groupId>
    <artifactId>poi-scratchpad</artifactId>
    <version>3.17</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.17</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml-schemas</artifactId>
    <version>3.17</version>
</dependency>

一、第一种方式
主类中编写一种替换方式编写文档

public static void main(String[] args) throws Exception {
    Map<String, String> map = new HashMap<>();
    map.put("${reportContent}", "这是一个难忘的季节");
    map.put("${date}", "2021-9-10");
    map.put("${author}", "cyz");
    map.put("${address}", "中国的一个小城市");
    XWPFDocument document = new XWPFDocument(POIXMLDocument.openPackage("D:\\word\\template.docx"));
    Iterator<XWPFParagraph> itPara = document.getParagraphsIterator();
    while (itPara.hasNext()) {
        XWPFParagraph paragraph = (XWPFParagraph) itPara.next();
        List<XWPFRun> runs = paragraph.getRuns();
        for (int i = 0; i < runs.size(); i++) {
            String oneparaString = runs.get(i).getText(runs.get(i).getTextPosition()).trim();
            for (Map.Entry<String, String> entry : map.entrySet()) {
                if (oneparaString.equals(entry.getKey())) {
                    oneparaString = oneparaString.replace(entry.getKey(), entry.getValue());
                }
            }
            runs.get(i).setText(oneparaString, 0);
        }
    }
    FileOutputStream outStream = null;
    outStream = new FileOutputStream("D:\\word\\write.docx");
    document.write(outStream);
    outStream.close();
}

首先我们在template.docx文档中将替换的内容编写好。
其次可以从数据库中获取相应的值，将替换内容当做key，数据库中获取的相应的值当做键值，最后将内容替换后写出到write.docx文档中即可。
二、第二种方式

public static void ExpReprot(HttpServletRequest request,HttpServletResponse response)throws Exception {
		
		response.setContentType("application/msword");
		response.setCharacterEncoding("utf-8");
		String fileName=URLEncoder.encode("生成报告文档","utf-8").replaceAll("\\+","%20");
		response.setHeader("Content-disposition", "attachment;filename*=utf-8''"+fileName+".doc");
		
		//创建word文档对象
		XWPFDocument document=new XWPFDocument();
		//创建标题
		XWPFParagraph title=document.createParagraph();
		//设置段落居中
		title.setAlignment(ParagraphAlignment.CENTER);
		
		XWPFRun titleRun=title.createRun();
		titleRun.setColor("00000");
		titleRun.setFontSize(25);
		titleRun.setFontFamily("仿宋");
		titleRun.setBold(true);
		titleRun.setText("生成报告文档信息");
		titleRun.addBreak();//换行
		
		//添加第一段落
		XWPFParagraph firstParagraph=document.createParagraph();
		//设置左对齐
		firstParagraph.setAlignment(ParagraphAlignment.LEFT);
		//---------------------以上设置整段的树形，以下设置内容
		XWPFRun firstRun=firstParagraph.createRun();
		firstRun.setColor("00000");
		firstRun.setFontSize(13);
		firstRun.setFontFamily("楷体");
		firstRun.setBold(true);
		firstRun.setText("这是一份有关于经济方面的报告，如何增长，如何促进本市的经济发展，促进消费，拉动经济。");
		firstRun.addBreak();//换行
		firstRun.addTab();//缩进
		firstRun.setText("虽然目前经济来说，由于疫情的影响，消费拉动经济确实有点困难，但线上的消费同样也可以促进经济发展，所以应该大力发展。");
		firstRun.addBreak();//换行
		//添加第二段落
		XWPFParagraph secondParagraph=document.createParagraph();
		secondParagraph.setAlignment(ParagraphAlignment.RIGHT);
		XWPFRun secondRun=firstParagraph.createRun();
		secondRun.setText("这是第二段落");
		
		document.write(response.getOutputStream());
		document.close();
		
	}
