JAVA根据模板生成WORD文件并导出

实现功能

根据模板生成WORD文件,模板文件参数可配.

一 : WORD导出效果

先看一下导出的demo文件,具体参数可手动修改
下图为word_demo.docx导出的WORD文件

下图为word_list.docx导出的WORD文件

二 : 编写WORD模板

WORD文件模板,新建WORD文件,将所需参数用特殊符号 ${} 配置,如下图.

demo模板(数据替换模板中的配置参数) : word_demo.docx

demo模板(导出数据列表,数据表格在文件下方自动拼接) : word_list.docx

三 : 引入所需maven依赖

项目采用springboot框架

	<!--WORD导出POM-->
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.8</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-scratchpad</artifactId>
        <version>3.8</version>
    </dependency>

WORD导出实体类(模板所需参数) WordResult.java

package com.chang.word;

import java.io.Serializable;
/**
 * WORD导出参数类
 * @author message丶小和尚
 * @create 2020/01/10
 */
public class WordResult implements Serializable {

    private static final long serialVersionUID = 1L;
    public String data;

    public String getData() {
        return data;
    }
    public void setData(String data) {
        this.data = data;
    }
}

五 : 配置信息说明

在WordExportService中,可设置导出的Word文件名.

在WordBaseService中,可设置Word模板配置的地址,以及配置模板名称

六 : 在固定位置插入表格

6.1 : 情况说明

在真实的业务场景中，可能会涉及Word中表格的导出。表格并不是拼接在文档末尾，而是设置在文档中，即某个段落与段落之间，类似下图这种情况。

对于这种在固定位置插入表格的情况，我们可采用同样的占位符的方式来实现。
如图所示，定义一个占位符 ${make_newTable}，当然里面的内容可以自己定义，需注意不能与文档中其他占位符同名即可。

6.2 : 编码实现

前提是前面的架子已经搭好。
这里的实现结果为标准表格导出，如果需要特殊表格，即合并单元格等，可改造该方法，对cell做特殊处理即可。
在WordTempleCommonService.java文件中增加方法如下：

	//通用导出WORD 包含list
    public static byte[] toWordCommonIndexList(Object obj,List<String> head,List<List<String>> list,String filePath) throws Exception{
        byte[] bytes = null;
        if(obj != null ){
            bytes = toWordAllModelAnalysisCommonIndexList(WordUtil.setMapObject(obj),head,list,WordConstant.TEMPLATE_BASE_PATH + filePath);
        }
        return bytes;
    }
	private static byte[] toWordAllModelAnalysisCommonIndexList(Map<String, Object> mapObject,List<String> head,List<List<String>> stringList, String modelPath) throws Exception {
        byte[] bytes = null;
        if(mapObject != null && !StringUtils.isEmpty(modelPath)){
            File file = new File(modelPath);
            if(!file.exists() && !file.isFile()){
                return null;
            }
            try {
                XWPFDocument doc = WordUtil.generateWord(mapObject, modelPath);
                ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
                List<XWPFParagraph> xwpfParagraphList = doc.getParagraphs();
                for(int s = 0; s < xwpfParagraphList.size(); s++){
                    XWPFParagraph xwpfParagraphIndex = xwpfParagraphList.get(s);
                    if("${make_newTable}".equals(xwpfParagraphIndex.getText())){
                        XmlCursor cursor = xwpfParagraphIndex.getCTP().newCursor();
                        XWPFTable table = doc.insertNewTbl(cursor);
                        //插入表格
                        table.getCTTbl().addNewTblPr().addNewJc().setVal(STJc.CENTER);//设置表格居中
                        //定义map
                        Map<Integer,Integer> map = new HashMap<Integer,Integer>();
                        //设置表头
                        XWPFTableRow tableRowOne = table.getRow(0);
                        for(String string:head){
                            Integer index = head.indexOf(string);//当前所处序号
                            Integer width = string.length() * 350 + 200;
                            if(0 == index && "序号".equals(string)){
                                width = 800;
                            }
                            map.put(index,width);
                            XWPFParagraph paragraph = getCommonIndexStyle(doc.createParagraph(), string, true);
                            if(0 == index){
                                tableRowOne.getCell(0).setParagraph(paragraph);
                                paragraph.removeRun(0);
                                tableRowOne.getCell(index).getCTTc().addNewTcPr().addNewTcW().setW(BigInteger.valueOf(width));//设置宽度
                                tableRowOne.getCell(0).getCTTc().addNewTcPr().addNewVAlign().setVal(STVerticalJc.CENTER);//设置水平居中
                                tableRowOne.getCtRow().addNewTrPr().addNewTrHeight().setVal(BigInteger.valueOf(600));
                            } else {
                                tableRowOne.addNewTableCell().setParagraph(paragraph);
                                paragraph.removeRun(0);
                                tableRowOne.getCell(index).getCTTc().addNewTcPr().addNewTcW().setW(BigInteger.valueOf(width));//设置宽度
                                tableRowOne.getCell(index).getCTTc().addNewTcPr().addNewVAlign().setVal(STVerticalJc.CENTER);//设置水平居中
                                tableRowOne.getCtRow().addNewTrPr().addNewTrHeight().setVal(BigInteger.valueOf(600));
                            }
                            doc.removeBodyElement(doc.getPosOfParagraph(paragraph));
                        }
                        //循环设置Word表格内容
                        for(List<String> list : stringList){
                            XWPFTableRow tableRow = table.createRow();
                            for(int i = 0; i < list.size(); i++){
                                CTTcPr tcpr = tableRow.getCell(i).getCTTc().addNewTcPr();
                                XWPFParagraph paragraph = getCommonIndexStyle(doc.createParagraph(), list.get(i), false);
                                tableRow.getCell(i).setParagraph(paragraph);
                                paragraph.removeRun(0);
                                tcpr.addNewTcW().setW(BigInteger.valueOf(map.get(i)));//设置宽度,表头设置了宽度,此处设置表头的宽度
                                tcpr.addNewVAlign().setVal(STVerticalJc.CENTER);//设置水平居中
                                tableRow.getCtRow().addNewTrPr().addNewTrHeight().setVal(BigInteger.valueOf(500));
                                doc.removeBodyElement(doc.getPosOfParagraph(paragraph));
                            }
                        }
                        doc.removeBodyElement(doc.getPosOfParagraph(xwpfParagraphIndex));
                    }
                }
                doc.write(byteArrayOutputStream);
                bytes = byteArrayOutputStream.toByteArray();
                byteArrayOutputStream.close();
            } catch (Exception e) {
                log.error("文件处理异常,Exception:", e);
            }
        }
        return bytes;
    }
    //设置通用段落格式
    private static XWPFParagraph getCommonIndexStyle(XWPFParagraph paragraphX, String name, boolean flag){
        paragraphX.setAlignment(ParagraphAlignment.CENTER);//对齐方式
        paragraphX.setVerticalAlignment(TextAlignment.CENTER);//对齐方式

        XWPFRun runXOne = paragraphX.createRun();//创建文本对象
        runXOne.setText(name);
        if(null == name){
            runXOne.setText("");
        }
        runXOne.setFontSize(12);//字体大小
        runXOne.setFontFamily("Calibri (正文)");//字体
        if(flag){
            runXOne.setBold(true);//加粗
        }
        runXOne.setTextPosition(10);//设置行间距
        return paragraphX;
    }

上述代码中需要注意的是：doc.removeBodyElement(doc.getPosOfParagraph(xwpfParagraphIndex));
这是由于我们在生成表格的时候，会去调用 doc.createParagraph()，创建段落，如果不去remove的话，会导致文档产生非常多的空白页。
方法getCommonIndexStyle，其主要作用即设置样式，如果想设置不同样式，可以自行设置即可。

然后在WordTempleService.java文件中增加方法如下：

	//指定位置插入表格 ${make_newTable}
    public void toWordCommonIndexList(HttpServletResponse response, Object object,List<String> head,List<List<String>> list,String wordTemplate,String fileName)throws Exception{
        byte[]  bytes = WordTempleCommonService.toWordCommonIndexList(object,head,list,wordTemplate);
        if(bytes != null){
            uploadWord(response,bytes,fileName);
        }
    }

上述代码的 uploadWord方法，可在文中找到。

至此方法已经搭建完成，下面是模拟调用。

wordTempleService.toWordCommonIndexList(response, templateDate, tableHead, tableData, wordTemplate, fileName);

参数说明：
response：响应头。
templateDate：Word模板导出的其他匹配数据。
tableHead：表格的表头。可使用Arrays.asList(“序号”, “姓名”)
tableData：表格的内容。
wordTemplate：模板的名称，需要注意路径问题。
fileName：导出的文件对应的文件名。

6.3 : 导出效果

七 : 可能出现的问题

在模板中配置参数 ${data} 时,可能会出现配置了参数,但是导出的时候赋值不了的情况,生成的Word中仍是 ${data} .
这种情况需要在代码中debug,找到对应的map,从代码中把对应的key复制到Word模板上.
如图所示复制一下,问题就可以解决了
