Java多种方式动态生成doc文档

本来是要在android端生成doc的（这需求...），最后方法没有好的方法能够在Android上做到完美，最后还是只能搬迁到服务器。不浪费，还是记录下各框架不支持Android的原因以及他们的特点。java相关的这类框架还是很多的，有几个还不错，可惜要么不支持Android，要么要收费还价格不低。

经过亲自测试，Android不支持Java的awt很多包不能直接在Android上用，FreeMarker挺不错的，能生成复杂漂亮的doc，可惜不支持Android。用POI在Android上能运行，但是一路因为版本，格式等走了很多坑，用WFS打开还是乱码。Jword、Aspose.word能完美支持，Jword试用期只有30天两者收费都不菲。itext没有测试，不过听说也不支持Android。

方法一：freemarker

该方法需要先手动创建一个doc模板（图片记得使用占位符），并保存为xml文件。通过动态替换特定标签${}中的内容生成。example:

先上效果图：

public class DocUtil {

public Configuration configure=null;

public DocUtil(){

configure=new Configuration(Configuration.VERSION_2_3_22);

configure.setDefaultEncoding("utf-8");

}

/**

* 根据Doc模板生成word文件

* @param dataMap 需要填入模板的数据

* @param downloadType 文件名称

* @param savePath 保存路径

public void createDoc(Map dataMap,String downloadType,String savePath){

try {

//加载需要装填的模板

Template template=null;

//设置模板装置方法和路径，FreeMarker支持多种模板装载方法。可以重servlet，classpath,数据库装载。

//加载模板文件，放在testDoc下

configure.setClassForTemplateLoading(this.getClass(), "/testDoc");

//设置对象包装器

// configure.setObjectWrapper(new DefaultObjectWrapper());

//设置异常处理器

configure.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER);

//定义Template对象，注意模板类型名字与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 dataMap=new HashMap();

dataMap.put("name", "Joanna");

dataMap.put("examNum", "111111111111");

dataMap.put("IDCard", "222222222222222222");

dataMap.put("carModel", "C1");

dataMap.put("drivingSchool", "测试驾校");

dataMap.put("busyType", "初次申领");

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号倒车入库，车身出线扣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，通过");

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文件太长，就不贴了...

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

补充关于动态显示list以及换行的问题

需求明确到：在上面的扣分项中，如果我有几条扣分项，我希望每显示一条换行。

直接在要显示的内容上加换行符，并没有什么效果，起不到换行的作用。

其中在加ftl标签时，如<#list>，就会出现一些问题，在xml中并不识别，导致项目不能运行。

解决：

在需要显示多条扣分项的位置加，并加换行符：

<#list firstDeductItem as firstItem>

${firstItem}

#list>

TestDoc.java中改为：

List Strs=new ArrayList();

Strs.add("1111111111111111111");

Strs.add("222222222222222");

Strs.add("333333333333333");

dataMap.put("firstDeductItem", Strs);

DocUtil.java中改为：

//定义Template对象，注意模板类型名字与downloadType要一致

template=configure.getTemplate(downloadType+".ftl");此时xml文件会报错，当然也不能编译运行项目，需要将.xml文件改为.ftl文件保存。再编译运行，效果图：

方法二：POI

用这个方法遇到了很多版本问题，这里是基于POI3.7+Word2007的，测试能够完美运行。

你需要用Word2007手动生成文档模板（用其他的生成会报错：无法打开文件），并用${}替换需要动态更新的内容，与上面类似，但是不需要你保存为xml文档格式了。
