java生成Word文件的三种方式

前期调研的itext,生成效果不行，版本太老，就不发出来了。

1.使用poi库生成

引入pom.xml

<dependency>
	<groupid>org.apache.poi</groupid>
	<artifactid>poi</artifactid>
	<version>4.1.0</version>
</dependency>


<dependency>
	<groupid>org.apache.poi</groupid>
	<artifactid>poi-ooxml</artifactid>
	<version>4.1.0</version>
</dependency>
生成文件代码

XWPFDocument document= new XWPFDocument();

//Write the Document in file system
FileOutputStream out = new FileOutputStream(new File("/Users/xxx/work/xxx/create_toc.docx"));

//添加标题
XWPFParagraph titleParagraph = document.createParagraph();

//设置段落居中
titleParagraph.setAlignment(ParagraphAlignment.CENTER);

XWPFRun titleParagraphRun = titleParagraph.createRun();
titleParagraphRun.setText("Java PoI");
titleParagraphRun.setColor("000000");
titleParagraphRun.setFontSize(20);

//段落
XWPFParagraph firstParagraph = document.createParagraph();
firstParagraph.getStyleID();
firstParagraph.setStyle("Heading1");
XWPFRun run = firstParagraph.createRun();
run.setText("段落1。");
run.setColor("696969");
run.setFontSize(18);


//段落
XWPFParagraph firstParagraph1 = document.createParagraph();
firstParagraph.setStyle("Heading1");
XWPFRun run1 = firstParagraph1.createRun();
run1.setText("段落2");
run1.setColor("696969");
run1.setFontSize(16);

document.createTOC();

document.write(out);
out.close();
这里有setStyle的参数Heading1,不知道哪里来的吧。看这里：word格式参考:http://www.ecma-international.org/publications/standards/Ecma-376.htm

即使有这个，我也没搞定样式问题，主要是有html的富文本内容，用这库完全不知道怎么做。

修改里面的段落，复制段落

依赖pom.xml

使用

package com.xx;


import cn.afterturn.easypoi.word.entity.MyXWPFDocument;

import com.xx.PoiUtil;

import org.apache.poi.xwpf.usermodel.*;
import org.apache.xmlbeans.XmlCursor;


import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;


public class PoiTest {
    public static void main(String args[]) throws Exception{
        FileInputStream inputStream=new FileInputStream(new File("/Users/chengzhong/code/workspace/cs-monitor-platform/indicator/src/main/resources/words/loop.docx"));
        String outFile="/Users/chengzhong/code/workspace/cs-monitor-platform/indicator/src/main/resources/words/loop2.docx";
        XWPFDocument document= new MyXWPFDocument(inputStream);

        PoiTest poiTest=new PoiTest();

        FileOutputStream out = new FileOutputStream(new File(outFile));

        String paragraphStartFlag="（{{addSeq}}）{{addName}}";

        new PoiUtil(){

            @Override
            public void insertNewParagraph(XWPFDocument document, int insertPos, XmlCursor insertCursor, XWPFParagraph paragraphTemplate) throws Exception {
                this.insertNewParagraphDefault(document,  insertPos,  insertCursor,  paragraphTemplate);
            }
        }.replaceParagraph(document,paragraphStartFlag);

        document.write(out);
        out.close();
    }


}
模板



2.直接往返回流里写html,不过response的context-type设置为doc.

业务代码:

StringBuffer sb=new StringBuffer();
sb.append("");
...
sb.append("");
OutputStream out=response.getOutputStream();
out.write(sb.toString().getBytes());
out.flush();
设置返回头:

String suffix=".doc";
String fileName="文件名";
String recommendedName;
//判断是否是IE11
Boolean flag = request.getHeader("User-Agent").indexOf("like Gecko") > 0;
if (request.getHeader("User-Agent").toLowerCase().indexOf("msie") > 0 || flag) {
    recommendedName = URLEncoder.encode(fileName, "UTF-8");//IE浏览器
} else {
    //先去掉文件名称中的空格,然后转换编码格式为utf-8,保证不出现乱码,
    //这个文件名称用于浏览器的下载框中自动显示的文件名
    recommendedName = new String(fileName.replaceAll(" ", "").getBytes("UTF-8"), "ISO8859-1");
}

response.setContentType("application/msword");

response.setHeader("Content-disposition", "attachment;filename=" + recommendedName + (suffix == null ? ".doc" : suffix));
OutputStream ouputStream = response.getOutputStream();
writeDoc(ouputStream,paperVo);
ouputStream.flush();
ouputStream.close();

这种方式在windows下的office word,wps都可以支持，但mac的pages不识别这个文件。


3.使用第三方模板库poi-tl

pom.xml引入:

<dependency>
  <groupId>com.deepoove</groupId>
  <artifactId>poi-tl</artifactId>
  <version>1.5.0</version>
</dependency>
首先建一个.docx的模板文件,例:

这里的{{变量名}}直接可替换为代码里的字符串，“变量名"前面有"+"号表示此处由另一个模板文件生成，并且是数组形式的。

生成代码:

public void create(TextModel tm,String filePath) throws IOException {
	tm.setChapters(new DocxRenderData(
			new File("folder/doc/template/chapters_segment.docx"), tm.getChapterList()));
	for(AttachSegment cs:tm.getChapterList()) {
		cs.setQuestions(new DocxRenderData(
				new File("folder/doc/template/question_segment.docx"), cs.getQuestionList()));
	}
	
	
	XWPFTemplate template = XWPFTemplate
			.compile("folder/doc/template/text_template.docx").render(tm);

	File file=new File(filePath);
	if(file.exists()) {
	//已存在文件，对其文件名进行"加1"方式重命名
		File children[]=file.getParentFile().listFiles();
		int nextSeq=1;
		int max=-1;
		for(File child:children) {
			if(child.getName().contains("_")) {
				String cName=child.getName();
				String numStr=cName.substring(cName.lastIndexOf("_")+1,cName.lastIndexOf(".")).trim();
				try {
					Integer n=Integer.valueOf(numStr);
					if(n>max) {
						max=n;
					}
				}catch(Exception e) {
					log.error("导出文件名错误，解析数据异常:"+filePath+ e.getMessage());
				}
			}
		}
		if(max!=-1) {
			nextSeq=max+1;
		}
		int end=filePath.lastIndexOf(".");
	
		file=new File(filePath.substring(0,end)+"_"+nextSeq+".docx");
		
	}
	FileOutputStream out = new FileOutputStream(file);
	template.write(out);
	template.close();
	out.flush();
	out.close();
}

这里有个换行问题需要注意,它比较显示显示效果。

1.以\n换行: office,wps正常显示,pages不换行
2.以\r\n换行:  office,pages(mac)正常显示,wps 会多显示一个空行
