导出word文档

一，添加jar包

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

二，准备好word文档，要doc格式。template.doc内容如下：

                                                       个人简历

姓名	${name}	性别	${sex}
年龄	${age}	出生日期	${date}

三，java编写：

       1，实体类：

package dkha.pojo;

import java.util.Date;

public class User {
    private String name;
    private String sex;
    private Integer age;
    private Date date;

    public User(String name, String sex, Integer age, Date date) {
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.date = date;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }
}

       2，读取word文件：

package dkha.tools;

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.*;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;

//读取文件类
public class ReadDoc {
    public void testReadByDoc(String path) throws Exception{
        InputStream is = new FileInputStream(path);
        HWPFDocument doc = new HWPFDocument(is);
        //输出书签信息
        this.printInfo(doc.getBookmarks());
        //输出文本
        System.out.println(doc.getDocumentText());
        Range range = doc.getRange();
        this.printInfo(range);
        //读表格
        this.readTable(range);
        //读列表
        this.readList(range);
        //把当前HWPFDocument写到输出流中
        doc.write(new FileOutputStream("D:\\test.doc"));
        is.close();

    }
    /**
     * 输出书签信息
     * @param bookmarks
     */
    private void printInfo(Bookmarks bookmarks) {
        int count = bookmarks.getBookmarksCount();
        System.out.println("书签数量：" + count);
        Bookmark bookmark;
        for (int i=0; i<count; i++) {
            bookmark = bookmarks.getBookmark(i);
            System.out.println("书签" + (i+1) + "的名称是：" + bookmark.getName());
            System.out.println("开始位置：" + bookmark.getStart());
            System.out.println("结束位置：" + bookmark.getEnd());
        }
    }

    /**
     * 读表格
     * 每一个回车符代表一个段落，所以对于表格而言，每一个单元格至少包含一个段落，每行结束都是一个段落。
     * @param range
     */
    private void readTable(Range range) {
        //遍历range范围内的table。
        TableIterator tableIter = new TableIterator(range);
        Table table;
        TableRow row;
        TableCell cell;
        while (tableIter.hasNext()) {
            table = tableIter.next();
            int rowNum = table.numRows();
            for (int j=0; j<rowNum; j++) {
                row = table.getRow(j);
                int cellNum = row.numCells();
                for (int k=0; k<cellNum; k++) {
                    cell = row.getCell(k);
                    //输出单元格的文本
                    System.out.println(cell.text().trim());
                }
            }
        }
    }

    /**
     * 读列表
     * @param range
     */
    private void readList(Range range) {
        int num = range.numParagraphs();
        Paragraph para;
        for (int i=0; i<num; i++) {
            para = range.getParagraph(i);
            if (para.isInList()) {
                System.out.println("list: " + para.text());
            }
        }
    }

    /**
     * 输出Range
     * @param range
     */
    private void printInfo(Range range) {
        //获取段落数
        int paraNum = range.numParagraphs();
        System.out.println(paraNum);
        for (int i=0; i<paraNum; i++) {
            System.out.println("段落" + (i+1) + "：" + range.getParagraph(i).text());
        }
        int secNum = range.numSections();
        System.out.println(secNum);
        Section section;
        for (int i=0; i<secNum; i++) {
            section = range.getSection(i);
            System.out.println(section.getMarginLeft());
            System.out.println(section.getMarginRight());
            System.out.println(section.getMarginTop());
            System.out.println(section.getMarginBottom());
            System.out.println(section.getPageHeight());
            System.out.println(section.text());
        }
    }
}

       3，写入word文件：

package dkha.tools;

import dkha.pojo.User;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.Range;
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.List;

//写入文件
public class WriteDoc {
    public void testWrite() throws Exception {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        List<User> list = new ArrayList<User>();
        list.add(new User("a","男",10,sdf.parse("2018-08-08")));
        list.add(new User("b","女",20,sdf.parse("2017-07-07")));

        String templatePath = "D:\\template.doc";
        InputStream is = new FileInputStream(templatePath);
        OutputStream os = null;
        HWPFDocument doc = new HWPFDocument(is);
        Range range = doc.getRange();
        for(int i=0;i<list.size();i++){
            User user = list.get(i);
            //把range范围内的${reportDate}替换为当前的日期
            range.replaceText("${name}", user.getName());
            range.replaceText("${sex}", user.getSex());
            range.replaceText("${age}", String.valueOf(user.getAge()));
            range.replaceText("${date}", sdf.format(user.getDate()));
             os = new FileOutputStream(new File("D:\\"+user.getName()+".doc"));
            //把doc输出到输出流中
            doc.write(os);
        }
        os.close();
        is.close();
    }
}

      4，测试：

package dkha.controller;

import dkha.tools.ReadDoc;
import dkha.tools.WriteDoc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
import java.io.File;

@Controller
@RequestMapping("/user")
public class IndexController {
    //读取文件
    @RequestMapping("/index")
    public String index(HttpServletRequest request){
        String str = request.getSession().getServletContext().getRealPath("/")+"WEB-INF"+File.separator+"JS";
        String path = str.replace("\\",File.separator)+File.separator+"template.doc";
        ReadDoc rd = new ReadDoc();
        try {
            rd.testReadByDoc(path);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "jsp/user";
    }
    //写入文件
    @RequestMapping("/index1")
    public void index1(HttpServletRequest request){
        String str = request.getSession().getServletContext().getRealPath("/")+"WEB-INF"+File.separator+"JS";
        String path = str.replace("\\",File.separator)+File.separator+"template.doc";
        WriteDoc wd = new WriteDoc();
        try {
            wd.testWrite();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
