spring 利用freemarker生成並導出word文檔

Word從2003開始支持XML格式，用XML還作就很簡單了。

大體的思路是先用office2003或者2007編輯好word的樣式，而後另存爲xml，以下圖所示：

將xml翻譯爲FreeMarker模板，最後用java來解析FreeMarker模板並輸出Doc，如圖所示的操做：

後臺生成word的代碼以下：

package net.gvsun.service;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.OutputStreamWriter;

import java.io.Writer;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import freemarker.template.Configuration;

import freemarker.template.Template;

import freemarker.template.TemplateException;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.OutputStreamWriter;

import java.io.Writer;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import freemarker.template.Configuration;

import freemarker.template.Template;

import freemarker.template.TemplateException;

public class WordHandler {

private Configuration configuration = null;

public WordHandler() {

configuration = new Configuration();

configuration.setDefaultEncoding("utf-8");

}

public File createDoc(String templatePath, String templateName, Map dataMap,String fileName) {

/* // 要填入模本的數據文件

Map dataMap = new HashMap();

getData(dataMap);*/

// 設置模本裝置方法和路徑,FreeMarker支持多種模板裝載方法。能夠重servlet，classpath，數據庫裝載，

// ftl文件存放路徑

configuration.setClassForTemplateLoading(this.getClass(), templatePath);

Template t = null;

try {

// test.ftl爲要裝載的模板

t = configuration.getTemplate(templateName);

t.setEncoding("utf-8");

} catch (IOException e) {

e.printStackTrace();

}

// 輸出文檔路徑及名稱

String root = System.getProperty("dhulims.root");

String upLoad=root+"upload"+File.separator;

//    File sendPath = new File(upLoad+projectNO);

File file = new File(upLoad);

if(!file.exists()){

file.mkdirs();

}

File outFile = new File(upLoad+fileName+".doc");

Writer out = null;

try {

out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"));

} catch (Exception e1) {

e1.printStackTrace();

}

try {

t.process(dataMap, out);

/*out.close();*/

} catch (TemplateException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return outFile;

}

public static void main(String templatePath, String templateName, Map dataMap,String fileName) {

new WordHandler().createDoc(templatePath,templateName,dataMap,fileName);

}

}

control導出word並傳入參數的代碼以下：

/**

@RequestMapping("/downloadLmsExperiment")

public void downloadLmsExperiment(@RequestParam int idKey,HttpServletResponse response)

{

response.setContentType("application/doc;charset=UTF-8");

 byte b[] = new byte[1024];   

//轉換startDate的時間格式；

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");

//根據主鍵idKey查找到LmsExperiment

LmsExperiment lmsexperiment=lmsExperimentDAO.findLmsExperimentByPrimaryKey(idKey);

//若是lmsexperiment的系部不爲空

if(lmsexperiment.getSysDepartment()!=null){

//映射lmsexperiment的departmentName給departName；

dataMap.put("departName",lmsexperiment.getSysDepartment().getDepartmentName());

}

//不然設置lmsexperiment的null爲departName

else{

dataMap.put("departName", "");

}

//映射lmsexperiment的experimentNumber給experimentNumber；

dataMap.put("experimentNumber",lmsexperiment.getExperimentNumber());

//映射Experiment的ExperimentName給ExperimentName；

dataMap.put("ExperimentName",lmsexperiment.getExperimentName());

 //映射lmsexperiment的experimentCardNumber給experimentCardNumber；

dataMap.put("experimentCardNumber",lmsexperiment.getExperimentCardNumber());

 //映射lmsexperiment的experimentMajor給experimentMajor；

dataMap.put("experimentMajor",lmsexperiment.getExperimentMajor());

 //映射lmsexperiment的totalCourseHours給totalCourseHours；

//映射lmsexperiment的totalExperimentHours給totalExperimentHours；

if(lmsexperiment.getSysCourse()!=null){

 //映射lmsexperiment的CourseName給courseName；

if(lmsexperiment.getLmsLab()!=null){

 //映射lmsexperiment的labName給labName；

}

//若是lmsexperiment的項目類型不爲空

if(lmsexperiment.getDataFieldByExperimentCategory()!=null){

 //映射lmsexperiment的categoryName給categoryName；

dataMap.put("categoryName",lmsexperiment.getDataFieldByExperimentCategory().getName());

}

//不然設置lmsexperiment的null爲categoryName

else{

dataMap.put("categoryName","");

}

WordHandler handler = new WordHandler();

//生成word

File outFile =handler.createDoc("/com/ftl", "AA.ftl", dataMap,lmsexperiment.getExperimentName());

//下面的代碼是導出word

FileInputStream in = null;

 OutputStream o = null;

 try {

 in = new FileInputStream(outFile);  

 o = response.getOutputStream();  

 response.setContentType("application/x-tar"); 

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

    + URLEncoder.encode(lmsexperiment.getExperimentName()+".doc", "UTF-8"));// 指定下載的文件名 

 response.setHeader("Content_Length",String.valueOf( outFile.length()));       // download the file.

       int n = 0;       

       while ((n = in.read (b))!= -1)

       {        

        o.write(b, 0, n);   

       } 

 } catch (Exception e) {

  e.printStackTrace();

 }finally{

   try {

    in.close();

    o.flush();

    o.close();

  } catch (IOException e) {

   e.printStackTrace();

  }

  

 }

}

經測試這樣方式生成導出word文檔徹底符合office標準，樣式、內容控制很是便利，打印也不會變形，生成的文檔和office中編輯文檔徹底同樣。
