java 导出word

1.首先新建Word，

另存为xml，再次打开编辑文件，如图所示，

mark改为${mark}然后把文件的扩展名改为ftl，就可以得到模板了。

2.(1)下面是后台代码UrlWordController.java

 

package com.itech.ups.app.activity.action;

import java.util.HashMap;
import java.util.Map;

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

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.itech.ups.base.web.action.AbstractActionParent;

@Controller
public class UrlWordController  extends AbstractActionParent {
 
 
    @RequestMapping(value = "expWord")
    @ResponseBody
    public void exportMillCertificate(HttpServletRequest request,
                      HttpServletResponse response) throws Exception {
        Map map = new HashMap();
        map.put("mark","哈哈哈");
        new UrlWord().exportMillCertificateWord(request,response,map);
    } 
 }

//这里注意的是利用UrlWord的类加载器动态获得模板文件的位置

public UrlWord(){

}

 

public  void exportMillCertificateWord(HttpServletRequest request, HttpServletResponse response,Map map) throws IOException {

File file = null;

// 调用工具类的createDoc方法生成Word文档

file = createDoc(map,freemarkerTemplate);

fin = new FileInputStream(file);

 

response.setCharacterEncoding("utf-8");

response.setContentType("application/msword");

// 设置浏览器以下载的方式处理该文件名也可以从浏览器传入

String fileName = "test"+new Date().getTime() + ".doc";

response.setHeader("Content-Disposition", "attachment;filename="

.concat(String.valueOf(URLEncoder.encode(fileName, "UTF-8"))));

 

out = response.getOutputStream();

byte[] buffer = new byte[512];  // 缓冲区

int bytesToRead = -1;

// 通过循环将读入的Word文件的内容输出到浏览器中

while((bytesToRead = fin.read(buffer)) != -1) {

out.write(buffer, 0, bytesToRead);

}

}catch(Exception o){

o.printStackTrace();

} finally {

if(fin != null) fin.close();

if(out != null) out.close();

if(file != null) file.delete(); // 删除临时文件

}

}

 

 private static File createDoc(Map dataMap, Template template) {
         String name =  "test.doc";//临时文件名
         File f = new File(name);
         Template t = template;
         try {
             // 这个地方不能使用FileWriter因为需要指定编码类型否则生成的Word文档会因为有无法识别的编码而无法打开
             Writer w = new OutputStreamWriter(new FileOutputStream(f), "utf-8");
