Java多種方式動態產生doc文檔_java

本來是要在Android端產生doc的(這需求...),最後方法沒有好的方法能夠在Android上做到完美,最後還是只能搬遷到伺服器。不浪費,還是記錄下各架構不支援Android的原因以及他們的特點。Java相關的這類架構還是很多的,有幾個還不錯,可惜要麼不支援Android,要麼要收費還價格不低。 

經過親自測試,Android不支援Java的awt很多包不能直接在Android上用,FreeMarker挺不錯的,能產生複雜漂亮的doc,可惜不支援Android。用POI在Android上能運行,但是一路因為版本,格式等走了很多坑,用WFS開啟還是亂碼。Jword、Aspose.word能完美支援,Jword試用期只有30天兩者收費都不菲。itext沒有測試,不過聽說也不支援Android。 

方法一:freemarker 

該方法需要先手動建立一個doc模板(圖片記得使用預留位置),並儲存為xml檔案。通過動態替換特定標籤${}中的內容產生。example: 

先上效果圖:

public class DocUtil { public Configuration configure=null;  public DocUtil(){  configure=new Configuration(Configuration.VERSION_2_3_22);  configure.setDefaultEncoding("utf-8"); } /**  * 根據Doc模板產生word檔案  * @param dataMap 需要填入模板的資料  * @param downloadType 檔案名稱  * @param savePath 儲存路徑  */ public void createDoc(Map<String,Object> dataMap,String downloadType,String savePath){  try {   //載入需要裝填的模板   Template template=null;   //設定模板裝置方法和路徑,FreeMarker支援多種模板裝載方法。可以重servlet,classpath,資料庫裝載。   //載入模板檔案,放在testDoc下   configure.setClassForTemplateLoading(this.getClass(), "/testDoc");   //設定對象封裝器//   configure.setObjectWrapper(new DefaultObjectWrapper());   //設定異常處理器   configure.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER);   //定義Template對象,注意模板類型名字與downloadType要一致   template=configure.getTemplate(downloadType+".xml");   File outFile=new File(savePath);   Writer out=null;   out=new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"));   template.process(dataMap, out);   out.close();  } catch (IOException e) {   e.printStackTrace();  } catch (TemplateException e) {   e.printStackTrace();  } }  public String getImageStr(String imgFile){  InputStream in=null;  byte[] data=null;  try {   in=new FileInputStream(imgFile);   data=new byte[in.available()];   in.read(data);   in.close();  } catch (FileNotFoundException e) {   e.printStackTrace();  } catch (IOException e) {   e.printStackTrace();  }  BASE64Encoder encoder=new BASE64Encoder();  return encoder.encode(data); }}
public class TestDoc { public static void main(String[] args) {  DocUtil docUtil=new DocUtil();  Map<String, Object> dataMap=new HashMap<String, Object>();  dataMap.put("name", "Joanna");  dataMap.put("examNum", "111111111111");  dataMap.put("IDCard", "222222222222222222");  dataMap.put("carModel", "C1");  dataMap.put("drivingSchool", "測試駕校");  dataMap.put("busyType", "初次申領");  dataMap.put("examDate", "2016-03-10");  dataMap.put("orderCount", "第1次");  dataMap.put("userImg1", docUtil.getImageStr("D:\\Img\\userImg1.png"));  dataMap.put("userImg2", docUtil.getImageStr("D:\\Img\\userImg2.png"));  dataMap.put("firstExamTime", "12:41:17-12:44:38");  dataMap.put("firstExamScores", "0分,不及格");  dataMap.put("firstDeductItem", "12:44:15 20102 1號倒車入庫,車身出線 扣100分");  dataMap.put("firstPic1", docUtil.getImageStr("D:\\Img\\firstPic1.png"));  dataMap.put("firstPic2", docUtil.getImageStr("D:\\Img\\firstPic2.png"));  dataMap.put("firstPic3", docUtil.getImageStr("D:\\Img\\firstPic3.png"));  dataMap.put("secondExamTime", "12:46:50-13:05:37");  dataMap.put("secondExamScores", "90分,通過");  dataMap.put("secondDeductItem", "");  dataMap.put("secondPic1", docUtil.getImageStr("D:\\Img\\secondPic1.png"));  dataMap.put("secondPic2", docUtil.getImageStr("D:\\Img\\secondPic2.png"));  dataMap.put("secondPic3", docUtil.getImageStr("D:\\Img\\secondPic3.png"));  docUtil.createDoc(dataMap, "baseDoc", "D:\\yanqiong.doc"); }}

xml檔案太長,就不貼了... 

最後附上Android不能使用的原因:http://stackoverflow.com/questions/25929542/use-freemarker-library-in-android 

補充關於動態顯示list以及換行的問題 

需求明確到:在上面的扣分項中,如果我有幾條扣分項,我希望每顯示一條換行。 

直接在要顯示的內容上加分行符號,並沒有什麼效果,起不到換行的作用。 

其中在加ftl標籤時,如<#list></list>,就會出現一些問題,在xml中並不識別,導致項目不能運行。 

解決: 

在需要顯示多條扣分項的位置加,並加分行符號: 

<#list firstDeductItem as firstItem>
     <w:t>${firstItem}</w:t><w:br/>
</#list>

TestDoc.java中改為: 

List<String> Strs=new ArrayList<String>();
Strs.add("1111111111111111111");
Strs.add("222222222222222");
Strs.add("333333333333333");
dataMap.put("firstDeductItem", Strs);

DocUtil.java中改為: 

//定義Template對象,注意模板類型名字與downloadType要一致
template=configure.getTemplate(downloadType+".ftl");此時xml檔案會報錯,當然也不能編譯運行項目,需要將.xml檔案改為.ftl檔案儲存。再編譯運行,效果圖: 

方法二:POI 

用這個方法遇到了很多版本問題,這裡是基於POI3.7+Word2007的,測試能夠完美運行。 

你需要用Word2007手動產生文件範本(用其他的產生會報錯:無法開啟檔案),並用${}替換需要動態更新的內容,與上面類似,但是不需要你儲存為xml文檔格式了。
