Java多種方法靜態生成doc文檔。本站提示廣大學習愛好者:(Java多種方法靜態生成doc文檔)文章只能為提供參考,不一定能成為您想要的結果。以下是Java多種方法靜態生成doc文檔正文
原來是要在Android端生成doc的(這需求...),最初辦法沒有好的辦法可以或許在Android上做到完善,最初照樣只能搬家到辦事器。不糟蹋,照樣記載下各框架不支撐Android的緣由和他們的特色。Java相干的這類框架照樣許多的,有幾個還不錯,惋惜要末不支撐Android,要末要免費討價格不低。
經由親身測試,Android不支撐Java的awt許多包不克不及直接在Android上用,FreeMarker挺不錯的,能生成龐雜英俊的doc,惋惜不支撐Android。用POI在Android上能運轉,然則一路由於版本,格局等走了許多坑,用WFS翻開照樣亂碼。Jword、Aspose.word能完善支撐,Jword試用期只要30天二者免費都不菲。itext沒有測試,不外據說也不支撐Android。
辦法一:freemarker
該辦法須要先手動創立一個doc模板(圖片記得應用占位符),並保留為xml文件。經由過程靜態調換特定標簽${}中的內容生成。example:
先上後果圖:
public class DocUtil {
public Configuration configure=null;
public DocUtil(){
configure=new Configuration(Configuration.VERSION_2_3_22);
configure.setDefaultEncoding("utf-8");
}
/**
* 依據Doc模板生成word文件
* @param dataMap 須要填入模板的數據
* @param downloadType 文件稱號
* @param savePath 保留途徑
*/
public void createDoc(Map<String,Object> dataMap,String downloadType,String savePath){
try {
//加載須要裝填的模板
Template template=null;
//設置模板裝配辦法和途徑,FreeMarker支撐多種模板裝載辦法。可以重servlet,classpath,數據庫裝載。
//加載模板文件,放在testDoc下
configure.setClassForTemplateLoading(this.getClass(), "/testDoc");
//設置對象包裝器
// configure.setObjectWrapper(new DefaultObjectWrapper());
//設置異常處置器
configure.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER);
//界說Template對象,留意模板類型名字與downloadType要分歧
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", "首次申領");
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,不合格");
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,經由過程");
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文件太長,就不貼了...
最初附上Android不克不及應用的緣由:http://stackoverflow.com/questions/25929542/use-freemarker-library-in-android
彌補關於靜態顯示list和換行的成績
需求明白到:在下面的扣分項中,假如我有幾條扣分項,我願望每顯示一條換行。
直接在要顯示的內容上加換行符,並沒有甚麼後果,起不到換行的感化。
個中在加ftl標簽時,如<#list></list>,就會湧現一些成績,在xml中其實不辨認,招致項目不克不及運轉。
處理:
在須要顯示多條扣分項的地位加,並加換行符:
<#list firstDeductItem as firstItem>
<w:t>${firstItem}</w:t><w:br/>
</#list>
TestDoc.java中改成:
List<String> Strs=new ArrayList<String>();
Strs.add("1111111111111111111");
Strs.add("222222222222222");
Strs.add("333333333333333");
dataMap.put("firstDeductItem", Strs);
DocUtil.java中改成:
//界說Template對象,留意模板類型名字與downloadType要分歧
template=configure.getTemplate(downloadType+".ftl");此時xml文件會報錯,固然也不克不及編譯運轉項目,須要將.xml文件改成.ftl文件保留。再編譯運轉,後果圖:
辦法二:POI
用這個辦法碰到了許多版本成績,這裡是基於POI3.7+Word2007的,測試可以或許完善運轉。
你須要用Word2007手動生成文檔模板(用其他的生成會報錯:沒法翻開文件),並用${}調換須要靜態更新的內容,與下面相似,然則不須要你保留為xml文檔格局了。
