关于使用freemarker导出word

java使用FreeMarker导出word

一、      先做一个word模板

二、      将该word文件另存为xml格式(注意是另存为,不是直接改扩展名)

三、     打开xml文件把要导出的文字都加上${xxx} 例如：${bianhao}

导出表格要在目标行（例如：bianhao这一行）的<w:tr></w:tr>标签包一个<#list xxx as xxx></#list> 例如：<#list userlist as userlist >标签，把要导出的文字都加上${ userlist . xxx} 例如：${ userlist . bianhao },保存后把xml文件后缀名改成  .ftl

四、      将文件保存到指定的文件夹下，在pom文件中导入FreeMarker.jar

<dependency>
  <groupId>org.freemarker</groupId>
  <artifactId>freemarker</artifactId>
  <version>2.3.20</version>
</dependency>

五、      Java代码如下（这里是一个测试方法）

import freemarker.template.Configuration;
import freemarker.template.TemplateException;

import java.io.*;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class WordTest {
    private Configuration configuration = null;

    public WordTest(){
        configuration = new Configuration();
        configuration.setDefaultEncoding("UTF-8");
    }

    public static void main(String[] args) {
        WordTest test = new WordTest();
        test.createWord();
    }

    public void createWord(){
        Map<String,Object> dataMap=new HashMap<String,Object>();
        getData(dataMap);
        //模板文件所在路径
//        configuration.setClassForTemplateLoading(this.getClass(), "");
        try {
            configuration.setDirectoryForTemplateLoading(new File("D:\\IdeaProjects\\SpringMVC\\src\\word"));
        } catch (IOException e) {
            e.printStackTrace();
        }
        freemarker.template.Template t=null;
        try {
            //获取模板文件
            t = configuration.getTemplate("test.ftl");
        } catch (IOException e) {
            e.printStackTrace();
        }
        //导出文件
        File outFile = new File("D:/outFile"+Math.random()*10000+".doc");
        Writer out = null;
        try {
            out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        }

        try {
            //将填充数据填入模板文件并输出到目标文件
            t.process(dataMap, out);
        } catch (TemplateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private void getData(Map<String, Object> dataMap) {
        dataMap.put("a", "/");
        dataMap.put("b", "名称");
        dataMap.put("c", "性别");
        dataMap.put("d", "电话");
        dataMap.put("e", "邮箱");
        dataMap.put("f", "职位");
        dataMap.put("A", "/");
        dataMap.put("B", "名称");
        dataMap.put("C", "经理");
        dataMap.put("D", "电话");
        dataMap.put("E", "邮箱");

        List<Map<String,Object>> userlist = new ArrayList<Map<String,Object>>();
        for (int i = 0; i < 50; i++) {
            Map<String,Object> map = new HashMap<String,Object>();
            map.put("bianhao", i);
            map.put("name", "刘慧文"+i);
            map.put("sex", "男"+i);
            map.put("phone", "15122693135"+i);
            map.put("email", "1305156911@qq.com"+i);
            map.put("zhiwei", "开发工程师"+i);
            userlist.add(map);
        }
        List<Map<String,Object>> deptlist = new ArrayList<Map<String,Object>>();
        for (int i = 0; i < 50; i++) {
            Map<String,Object> map = new HashMap<String,Object>();
            map.put("BIANHAO", i);
            map.put("NAME", "刘慧文"+i);
            map.put("JINGLI", "张经理"+i);
            map.put("PHONE", "15122693135"+i);
            map.put("EMAIL", "1305156911@qq.com"+i);
            deptlist.add(map);
        }

        dataMap.put("userlist", userlist);
        dataMap.put("deptlist", deptlist);
    }
}

六、      导出效果
