freemarker導出word

1.新建word文檔，導出預期以下

2.另存爲xml文件

3.編輯xml，將文字替換成表達式 ${argname}

原圖:

替換後 ：

年齡、職位、項目、簡述對應的值依次替換成 ${age} ${position} ${project} ${note}

4.修改文件名稱爲:ftl2doc.ftl,放到項目裏

5.查看pom依賴是否添加若沒有需添加freemarker依賴

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-freemarker</artifactId>
		</dependency>

6.編寫工具類

package org.jeecg.modules.system.util;

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.URLEncoder;
import java.util.Locale;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import freemarker.template.*;

public class FreemarkerUtil {
    private static final Object LOCK = new Object();

    private static Configuration cfg;

    private static FreemarkerUtil ftl ;

    private FreemarkerUtil(File file) throws IOException {
        cfg = new Configuration();
        cfg.setDirectoryForTemplateLoading(file);
        cfg.setEncoding(Locale.getDefault(), "UTF-8");
        cfg.setObjectWrapper(new DefaultObjectWrapper());
    }

    private static void check(File file) {
        if (ftl == null) {
            synchronized (LOCK) {
                try {
                    ftl = new FreemarkerUtil(file);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }


    /**
     * 建立 word 文檔
     * 必須先設置response導出配置，而後解析模版，不然會出問題
     * @throws IOException
     */
    public static void createFile(File templateDir,String templateName,String docFileName, Map<String,Object> rootMap,HttpServletRequest request, HttpServletResponse response) throws IOException {
        //  	response.resetBuffer();
        //設置導出
        response.addHeader("Cache-Control","no-cache");
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/vnd.ms-word;charset=UTF-8");
        String ua = request.getHeader("user-agent");
        ua = ua == null ? null : ua.toLowerCase();
        if(ua != null && (ua.indexOf("firefox") > 0 || ua.indexOf("safari")>0)){
            try {
                docFileName = new String(docFileName.getBytes(),"ISO8859-1");
                response.addHeader("Content-Disposition","attachment;filename=" + docFileName);
            } catch (Exception e) {
            }
        }else{
            try {
                docFileName = URLEncoder.encode(docFileName, "utf-8");
                response.addHeader("Content-Disposition","attachment;filename=" + docFileName);
            } catch (Exception e) {
            }
        }
        check(templateDir);
        //解析模版
        Template temp = cfg.getTemplate(templateName, "UTF-8");
        PrintWriter write = response.getWriter();
        try {
            temp.process(rootMap, write);
        } catch (TemplateException e) {
            e.printStackTrace();
        }finally {
            if(write != null){
                write.flush();
                write.close();
            }
        }
    }
}

7.測試接口

@Resource
    private ResourceLoader resourceLoader;
    @GetMapping(value = "/wordTest")
    public void wordTest(HttpServletRequest req,HttpServletResponse resp){
        String path = "templates/word";
        org.springframework.core.io.Resource resource = resourceLoader.getResource("classpath:"+path);
        try {
            File file = resource.getFile();
            Map<String,Object> map = new HashMap<String,Object>();
	    //這裏map的key和上面模板內的${key}保持一致便可
            map.put("name", "劉禹錫");
            map.put("age", 26);
            map.put("position", "php開發");
            map.put("project", "不動產登記項目");
            map.put("note", "php是世界上最好的語言！！！");
            String docFileName ="word-模板導出測試.doc";
            String templateName = "ftl2doc.ftl";
            FreemarkerUtil.createFile(file,templateName,docFileName, map, req, resp);
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

測試結果導出文件以下：
