导出word文档

灰太狼 2022-01-31 06:55 515阅读 0赞

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**

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();
            }
        }
    }
