ftl生成模板并从前台下载

1.生成模板的工具类

package com.jesims.busfundcallnew.util;

import freemarker.template.Configuration;
import freemarker.template.Template;
import org.activiti.engine.impl.bpmn.data.Data;

import java.io.*;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Map;

public class WordUtil {
    public static  void createWord(Map<String,Object> dataMap, String templateName, String filePath, String fileName){
        try {
            //创建配置实例
            Configuration configuration = new Configuration();
            //设置编码
            configuration.setDefaultEncoding("UTF-8");

            //设置编码
            //configuration.setDefaultEncoding("UTF-8");

////            ftl模板文件统一放至 com.lun.template 包下面
//            configuration.setClassForTemplateLoading(this.getClass(), "com.jesims.modules.freemarker.entity");
//            request.getSession().getServletContext().getRealPath("/WEB-INF/ftl")  获取文件夹下面的所有模版
//             configuration.setDirectoryForTemplateLoading(new File(request.getSession().getServletContext().getRealPath("/WEB-INF/ftl")));

            configuration.setDirectoryForTemplateLoading(new File("C:\\Project\\huajinziben\\hjzb2\\src\\main\\webapp\\WEB-INF\\attachment"));// 本地模板路径
            //获取模板
            Template template = configuration.getTemplate(templateName);
            //输出文件
            File outFile = new File(filePath+File.separator+fileName);

            //如果输出目标文件夹不存在，则创建
            if (!outFile.getParentFile().exists()){
                outFile.getParentFile().mkdirs();
            }

            //将模板和数据模型合并生成文件
            Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile),"UTF-8"));

            //生成文件
            template.process(dataMap, out);

            //关闭流
            out.flush();
            out.close();




            
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

public static void download (HttpServletResponse response,String pathName,String fileName){
    OutputStream outputStream = null;
    BufferedInputStream bis = null;
    BufferedOutputStream bos = null;
    InputStream inStream = null;
    try {
        // 读到流中
        File file = new File(pathName);
        inStream = new FileInputStream(file);
        response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8");
        response.setHeader("Content-Disposition", "attachment;filename=" + new String((fileName + ".doc").getBytes(), "iso-8859-1"));
        outputStream = response.getOutputStream();
        bis = new BufferedInputStream(inStream);
        bos = new BufferedOutputStream(outputStream);
        byte[] buff = new byte[8192];
        int bytesRead;
        while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
            bos.write(buff, 0, bytesRead);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (null != bis) {
                bis.close();
            }
            if (null != bos) {
                bos.close();
            }
            if (null != outputStream) {
                outputStream.flush();
                outputStream.close();
            }
        } catch (IOException e) {
        }
    }

}

}

 

2.调用

 

 

 

 

 

3.定义好模板

 

 

 

4.转成ftl文件

首先转成 Word 2003 XML 文档

 

 

 然后将 xml后缀改为 ftl

 

 

5.替换关键字

 

 

 

6.前端调用并下载word

前端 绑定点击事件：

 

 

 注 ：前端下载 需要用  

window.location.href  
 不然不能下载



下载word

OutputStream outputStream = null;
        BufferedInputStream bis = null;
        BufferedOutputStream bos = null;
        InputStream inStream = null;
        try {
            // 读到流中
            File file = new File("C:\\Users\\18300\\Desktop\\aaa\\基金call款通知书.doc"); //文件路径+文件名称
            inStream = new FileInputStream(file);
            String fileName = "基金call款通知书";// 生成的文件名称
            response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8");
            response.setHeader("Content-Disposition", "attachment;filename=" + new String((fileName + ".doc").getBytes(), "iso-8859-1"));

            outputStream = response.getOutputStream();

            bis = new BufferedInputStream(inStream);
            bos = new BufferedOutputStream(outputStream);
            byte[] buff = new byte[8192];
            int bytesRead;
            while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
                bos.write(buff, 0, bytesRead);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != bis) {
                    bis.close();
                }
                if (null != bos) {
                    bos.close();
                }
                if (null != outputStream) {
                    outputStream.flush();
                    outputStream.close();
                }
            } catch (IOException e) {
            }
        }

 

7.导出结果

 

springBoot+vue 前台下载应该这么写  不然上生产下载有问题：

    exportHandle() {
      this.loading = true
      // 准备下载
      axios({
        method: 'post',
        url: process.env.VUE_APP_BASE_API + '/dashboard/export',
        data: this.queryParams,
        responseType: 'blob',
        headers: { 'Authorization': 'Bearer ' + getToken() }
      }).then(res => {
        const blob = res.data
        const reader = new FileReader()
        reader.readAsDataURL(blob)
        reader.onload = (e) => {
          const a = document.createElement('a')
          // 文件名称
          const fileName = '【Dashboard报表】'
          a.download = fileName + `.doc`
          a.href = e.target.result
          document.body.appendChild(a)
          a.click()
          document.body.removeChild(a)
          this.loading = false
        }
      })
    }

 

 4.0后台获取模板    上述方式获取模板在测试环境不好使

    @Resource(name = "wordConfiguration")
    private Configuration wordConfiguration;


  　　　　String reportPath = RuoYiConfig.getProfile();
        LogUtils.info("------------------报告生成临时目录：" + reportPath + "--------------------------");
        String fileTempName = UUID.randomUUID().toString();
        response.setCharacterEncoding("UTF-8");
        Template template = wordConfiguration.getTemplate("companyPortalBase" + ".ftl", "utf-8");
        WordUtil.createWord(map, "companyPortalBase.ftl", reportPath, fileTempName+".doc", this, template);
